• How to add a startup/shutdown script to the GPO from the command line

  - by thomasjames

  I need to add startup and shutdown scripts from a CLI through a Powershell/Python/CMD script. Ideally, I would like to have the same functionality as gpedit.msc, but it is important that the tasks of adding and removing such scripts do not require user interaction and can be done entirely within the context of a script. Currently, the scripts here seem to be in the same category, but none of them explicitly address editing startup and shutdown scripts: http://msdn.microsoft.com/en-us/library/aa814151(v=vs.85).aspx Let me know if anyone has any ideas and thanks in advance.

• Driver corruption when deploying Dell Touchpad Drivers (with software) during imaging process

  - by BigHomie

  We're an sccm shop, and use it to deploy Windows. When deploying Dell laptops (multiple models), the touchpad drivers seem install properly, but the software doesn't. The resulting problem is that when the touchpad is pressed on occasion, the mouse pointer will 'jump' to certain points on the screen. A possible symptom of this problem/visible sign is if the touchpad icon isn't in the system tray. The software is in the control panel, but when opened part of the gui is pixelated, indicating botched install maybe? The manual resolution to this, is to go into device manager and uninstall the driver with the option to uninstall all driver software. After a restart, the driver and software is apparently reinstalled, and from there works as expected. Obviously this partially defeats the purpose of a zero touch deployment. If anyone knows why this is and/or a possible workaround, those answers would be valid as well. Barring that, I want to find a way to deploy the driver and touchpad software in an unattended way, so that it can be conditionally installing during the imaging process. To be honest I'm not sure how to troubleshoot this, I suppose I could try drvinst.exe to install the driver, but finding out why this fails initially would keep me from spinning my wheels.

• If a SQL Server Replication Distributor and Subscriber are on the same server, should a PUSH or PULL subsciption be used?

  - by userx

  Thanks in advance for any help. I'm setting up a new Microsoft SQL Server replication and I have the Distributor and Subscriber running on the same server. The Publisher is on a remote server (as it is a production database and MS recommends that for high volumes, the Distributor should be remote). I don't know much about the inner workings of PUSH vs PULL subscriptions, but my gut tells me that a PUSH subscription would be less resource intensive because (1) the Distributor is already remote, so this shouldn't negatively effect the Publisher and (2) pushing the transactions from the Distributor to the Subscriber is more efficient than the Subscriber polling the Distribution database. Does any one have any resources or insight into PUSH vs PULL which would recommend one over the other? Is there really going to be that big of a difference in performance / reliability / security?

  - by Tyron Gower

  Have an issue where onsite clients cannot resolve VPNusers. but VPN users can resolve onsite machines. example. USER! uses LAPTOP1 USER1 connects to VPN gets internal IP address of 10.243.0.200 USER1 pings SERVER1 - resolve to ip and gets reply USER1 RDP into SERVER1 (inside VPN) USER1 pings LAPTOP1 from SERVER1 resolves to ip address last assigned by DHCP (10.243.0.139) ping fails USER1 pings 10.243.0.200 from SERVER1 gets reply. Running Server 2012r2 It is a domain controller, DNS and VPN server. VPN is just configured with basic default settings. All VPN users have static IP setup in AD. Not sure where to go from here.

• Minimal Lync 2013 Setup

  - by vkapadia

  I would like to install a Lync 2013 server at home. What would be the minimum requirements for it? I've seen the requirements and they seem pretty hefty, just want to know what I need for a basic set up. This will be for up to 5 users. I would like users to be able to connect from outside the network as well. From what I've been able to find, it looks like I'll need 3 servers. A domain controller, a lync front end server, and an edge server (for external connectivity, and it will need 2 network cards). Is that really all necessary? And how would they need to be connected (I've never connected a machine with multiple network cards)? Do they all have to be separate machines, or can I use VMs?

• Provide a user with service start/stop permissions

  - by slakr007

  I have a very basic domain that I use for development. I want to create a GPO that provides users in the Backup Operators group with start/stop permissions for two specific services on a specific server. I have read several articles about this, and they all indicate that this is very easy. Create a GPO, give the user start/stop permissions to the services under Computer Configuration Policies Windows Settings Security Settings System Services, and voila. Done. Not so much, but I have to be doing something wrong. My install is pretty much the default. The domain controller is in the Domain Controllers OU, the Backup Operators group is under Builtin, and I created a user called Backup under Users. I created a GPO and linked it to the Domain Controllers OU. In the GPO I give the Backup user permission to start/stop two specific services on the server. I forced an update with gpupdate. I used Group Policy Results to verify that my GPO is the winning GPO giving the user the permission to start/stop the two services. However, the user is still unable to start/stop the services. I attempted different loopback settings on the GPO to no avail. I'm sort of at a loss here.

• It&rsquo;s A Team Sport: PASS Board Year 2, Q3

  - by Denise McInerney

  As I type this I’m on an airplane en route to my 12th PASS Summit. It’s been a very busy 3.5 months since my last post on my work as a Board member. Nearing the end of my 2-year term I am struck by how much has happened, and yet how fast the time has gone. But I’ll save the retrospective post for next time and today focus on what happened in Q3. In the last three months we made progress on several fronts, thanks to the contributions of many volunteers and HQ staff members. They deserve our appreciation for their dedication to delivering for the membership week after week. Virtual Chapters The Virtual Chapters continue to provide many PASS members with valuable free training. Between July and September of 2013 VCs hosted over 50 webinars with a total of 4300 attendees. This quarter also saw the launch of the Security & Global Russian VCs. Both are off to a strong start and I welcome these additions to the Virtual Chapter portfolio. At the beginning of 2012 we had 14 Virtual Chapters. Today we have 22. This growth has been exciting to see. It has also created a need to have more volunteers help manage the work of the VCs year-round. We have renewed focus on having Virtual Chapter Mentors work with the VC Leaders and other volunteers. I am grateful to volunteers Julie Koesmarno, Thomas LeBlanc and Marcus Bittencourt who join original VC Mentor Steve Simon on this team. Thank you for stepping up to help. Many improvements to the VC web sites have been rolling out over the past few weeks. Our marketing and IT teams have been busy working a new look-and-feel, features and a logo for each VC. They have given the VCs a fresh, professional look consistent with the rest of the PASS branding, and all VCs now have a logo that connects to PASS and the particular focus of the chapter. 24 Hours of PASS The Summit Preview edition  of 24HOP was held on July 31 and by all accounts was a success. Our first use of the GoToWebinar platform for this event went extremely well. Thanks to our speakers, moderators and sponsors for making this event possible. Special thanks to HQ staffers Vicki Van Damme and Jane Duffy for a smoothly run event. Coming up: the 24HOP Portuguese Edition will be held November 13-14, followed December 12-13 by the Spanish Edition. Thanks to the Portuguese- and Spanish-speaking community volunteers who are organizing these events. July Board Meeting The Board met July 18-19 in Kansas City. The first order of business was the election of the Executive Committee who will take office January 1. I was elected Vice President of Marketing and will join incoming President Thomas LaRock, incoming Executive Vice President of Finance Adam Jorgensen and Immediate Past President Bill Graziano on the Exec Co. I am honored that my fellow Board members elected me to this position and look forward to serving the organization in this role. Visit to PASS HQ In late September I traveled to Vancouver for my first visit to PASS HQ, where I joined Tom LaRock and Adam Jorgensen to make plans for 2014.  Our visit was just a few weeks before PASS Summit and coincided with the Board election, and the office was humming with activity. I saw first-hand the enthusiasm and dedication of everyone there. In each interaction I observed a focus on what is best for PASS and our members. Our partners at HQ are key to the organization’s success. This week at PASS Summit is a great opportunity for all of us to remember that, and say “thanks.” Next Up PASS Summit—of course! I’ll be around all week and look forward to connecting with many of our member over meals, at the Community Zone and between sessions. In the evenings you can find me at the Welcome Reception, Exhibitor’s Reception and Community Appreciation Party. And I will be at the Board Q&A session  Friday at 12:45 p.m. Transitions The newly elected Exec Co and Board members take office January 1, and the Virtual Chapter portfolio is transitioning to a new director. I’m thrilled that Jen Stirrup will be taking over. Jen has experience as a volunteer and co-leader of the Business Intelligence Virtual Chapter and was a key contributor to the BI VCs expansion to serving our members in the EMEA region. I’ll be working closely with Jen over the next couple of months to ensure a smooth transition.

• Pass-by-Reference Error

  - by TK

  I have a hook system setup... which is working on localhost... I put it live and get an error saying "Warning: Call-time pass-by-reference has been deprecated". Now, apparently the work around is to remove all "&" from your function calls, ie foo(&$me) to foo($me) and then in foo's function definition do "function foo(&$me)". However, I can not do this... because my hooks accept an array as arguments, I need a work around for this. Like I can use "run_hooks ( 'hook-name', $me );" or "run_hooks ( 'hook-name', array ( $me, $another_var, etc... ) )"; So this means I can not use "function run_hooks ( $hook_name, &$arguments )" because I'll get an error in php saying it can not pass "array()" as reference... Any ideas an a work around? Thanks.

• The Changing Face of PASS

  - by Bill Graziano

  I’m starting my sixth year on the PASS Board.  I served two years as the Program Director, two years as the Vice-President of Marketing and I’m starting my second year as the Executive Vice-President of Finance.  There’s a pretty good chance that if PASS has done something you don’t like or is doing something you don’t like, that I’m involved in one way or another. Andy Leonard asked in a comment on his blog if the Board had ever reversed itself based on community input.  He asserted that it hadn’t.  I disagree.  I’m not going to try and list all the changes we make inside portfolios based on feedback from and meetings with the community.  I’m going to focus on major governance issues since I was elected to the Board. Management Company The first big change was our management company.  Our old management company had a standard approach to running a non-profit.  It worked well when PASS was launched.  Having a ready-made structure and process to run the organization enabled the organization to grow quickly.  As time went on we were limited in some of the things we wanted to do.  The more involved you were with PASS, the more you saw these limitations.  Key volunteers were regularly providing feedback that they wanted certain changes that were difficult for us to accomplish.  The Board at that time wanted changes that were difficult or impossible to accomplish under that structure. This was not a simple change.  Imagine a $2.5 million dollar company letting all its employees go on a Friday and starting with a new staff on Monday.  We also had a very narrow window to accomplish that so that we wouldn’t affect the Summit – our only source of revenue.  We spent the year after the change rebuilding processes and putting on the Summit in Denver.  That’s a concrete example of a huge change that PASS made to better serve its members.  And it was a change that many in the community were telling us we needed to make. Financials We heard regularly from our members that they wanted our financials posted.  Today on our web site you can find audited financials going back to 2004.  We publish our budget at the start of each year.  If you ask a question about the financials on the PASS site I do my best to answer it.  I’m also trying to do a better job answering financial questions posted in other locations.  (And yes, I know I owe a few of you some blog posts.) That’s another concrete example of a change that our members asked for that the Board agreed was a good decision. Minutes When I started on the Board the meeting minutes were very limited.  The minutes from a two day Board meeting might fit on one page.  I think we did the bare minimum we were legally required to do.  Today Board meeting minutes run from 5 to 12 pages and go into incredible detail on what we talk about.  There are certain topics that are NDA but where possible we try to list the topic we discussed but that the actual discussion was under NDA.  We also publish the agenda of Board meetings ahead of time. This is another specific example where input from the community influenced the decision.  It was certainly easier to have limited minutes but I think the extra effort helps our members understand what’s going on. Board Q&A At the 2009 Summit the Board held its first public Q&A with our members.  We’d always been available individually to answer questions.  There’s a benefit to getting us all in one room and asking the really hard questions to watch us squirm.  We learn what questions we don’t have good answers for.  We get to see how many people in the crowd look interested in the various questions and answers. I don’t recall the genesis of how this came about.  I’m fairly certain there was some community pressure though. Board Votes Until last November, the Board only reported the vote totals and not how individual Board members voted.  That was one of the topics at a great lunch I had with Tim Mitchell and Kendal van Dyke at the Summit.  That was also the topic of the first question asked at the Board Q&A by Kendal.  Kendal expressed his opposition to to anonymous votes clearly and passionately and without trying to paint anyone into a corner.  Less than 24 hours later the PASS Board voted to make individual votes public unless the topic was under NDA.  That’s another area where the Board decided to change based on feedback from our members. Summit Location While this isn’t actually a governance issue it is one of the more public decisions we make that has taken some public criticism.  There is a significant portion of our members that want the Summit near them.  There is a significant portion of our members that like the Summit in Seattle.  There is a significant portion of our members that think it should move around the country.  I was one that felt strongly that there were significant, tangible benefits to our attendees to being in Seattle every year.  I’m also one that has been swayed by some very compelling arguments that we need to have at least one outside Seattle and then revisit the decision.  I can’t tell you how the Board will vote but I know the opinion of our members weighs heavily on the decision. Elections And that brings us to the grand-daddy of all governance issues.  My thesis for this blog post is that the PASS Board has implemented policy changes in response to member feedback.  It isn’t to defend or criticize our election process.  It’s just to say that is has been under going continuous change since I’ve been on the Board.  I ran for the Board in the fall of 2005.  I don’t know much about what happened before then.  I was actively volunteering for PASS for four years prior to that as a chapter leader and on the program committee.  I don’t recall any complaints about elections but that doesn’t mean they didn’t occur.  The questions from the Nominating Committee (NomCom) were trivial and the selection process rudimentary (For example, “Tell us about your accomplishments”).  I don’t even remember who I ran against or how many other people ran.  I ran for the VP of Marketing in the fall of 2007.  I don’t recall any significant changes the Board made in the election process for that election.  I think a lot of the changes in 2007 came from us asking the management company to work on the election process.  I was expecting a similar set of puff ball questions from my previous election.  Boy, was I in for a shock.  The NomCom had found a much better set of questions and really made the interview portion difficult.  The questions were much more behavioral in nature.  I’d already written about my vision for PASS and my goals.  They wanted to know how I handled adversity, how I handled criticism, how I handled conflict, how I handled troublesome volunteers, how I motivated people and how I responded to motivation. And many, many other things. They grilled me for over an hour.  I’ve done a fair bit of technical sales in my time.  I feel I speak well under pressure addressing pointed questions.  This interview intentionally put me under pressure.  In addition to wanting to know about my interpersonal skills, my work experience, my volunteer experience and my supervisory experience they wanted to see how I’d do under pressure.  They wanted to see who would respond under pressure and who wouldn’t.  It was a bit of a shock. That was the first big change I remember in the election process.  I know there were other improvements around the process but none of them stick in my mind quite like the unexpected hour-long grilling. The next big change I remember was after the 2009 elections.  Andy Warren was unhappy with the election process and wanted to make some changes.  He worked with Hannes at HQ and they came up with a better set of processes.  I think Andy moved PASS in the right direction.  Nonetheless, after the 2010 election even more people were very publicly clamoring for changes to our election process.  In August of 2010 we had a choice to make.  There were numerous bloggers criticizing the Board and our upcoming election.  The easy change would be to announce that we were changing the process in a way that would satisfy our critics.  I believe that a knee-jerk response to criticism is seldom correct. Instead the Board spent August and September and October and November listening to the community.  I visited two SQLSaturdays and asked questions of everyone I could.  I attended chapter meetings and asked questions of as many people as they’d let me.  At Summit I made it a point to introduce myself to strangers and ask them about the election.  At every breakfast I’d sit down at a table full of strangers and ask about the election.  I’m happy to say that I left most tables arguing about the election.  Most days I managed to get 2 or 3 breakfasts in. I spent less time talking to people that had already written about the election.  They were already expressing their opinion.  I wanted to talk to people that hadn’t spoken up.  I wanted to know what the silent majority thought.  The Board all attended the Q&A session where our members expressed their concerns about a variety of issues including the election. The PASS Board also chose to create the Election Review Committee.  We wanted people from the community that had been involved with PASS to look at our election process with fresh eyes while listening to what the community had to say and give us some advice on how we could improve the process.  I’m a part of this as is Andy Warren.  None of the other members are on the Board.  I’ve sat in numerous calls and interviews with this group and attended an open meeting at the Summit.  We asked anyone that wanted to discuss the election to come speak with us.  The ERC held an open meeting at the Summit and invited anyone to attend.  There are forums on the ERC web site where we’ve invited people to participate.  The ERC has reached to key people involved in recent elections.  The years that I haven’t mentioned also saw minor improvements in the election process.  Off the top of my head I don’t recall what exact changes were made each year.  Specifically since the 2010 election we’ve gone out of our way to seek input from the community about the process.  I’m not sure what more we could have done to invite feedback from the community. I think to say that we haven’t “fixed” the election process isn’t a fair criticism at this time.  We haven’t rushed any changes through the process.  If you don’t see any changes in our election process in July or August then I think it’s fair to criticize us for ignoring the community or ask for an explanation for what we’ve done. In Summary Andy’s main point was that the PASS Board hasn’t changed in response to our members wishes.  I think I’ve shown that time and time again the PASS Board has changed in response to what our members want.  There are only two outstanding issues: Summit location and elections.  The 2013 Summit location hasn’t been decided yet.  Our work on the elections is also in progress.  And at every step in the election review we’ve gone out of our way to listen to the community and incorporate their feedback on the process. I also hope I’m not encouraging everyone that wants some change in the organization to organize a “blog rush” against the Board.  We take public suggestions very seriously but we also take the time to evaluate those suggestions and learn what the rest of our members think and make a measured decision.

• How mod_cache working with "must-revalidate" and "max-age"?

  - by Dmitriy Sosunov

  Quick question before I will explain my flow: ?an mod_cache perform revalidate with if-none-match only if max-age is expired in case if it configured in reverse proxy mode? My goal is to reduce a number of revalidation requests to our the origin server. For instance: The first request goes to the origin server and then mod_cache save a response in to the cache according to header cache-control: max-age. And only when max-age is expired then mod_cache will revalidate with if-none-match. Currently, mod_cache revalidate each request, regardless that max-age is defined or not. My configuration of Apache 2.4.3 (Windows), on linux I see the same behavior that I will show below. ServerName proxy.lo ProxyRequests Off ProxyPreserveHost Off Header set Vary "Accept, Content-Type, Content-Encoding, Accept-Language" RequestHeader set X-Forwarded-Proto "http" # modify header for user agent's Header set Cache-Control "private, no-cache, no-store, no-transform" CacheQuickHandler off CacheDefaultExpire 300 # the origin server do not provide last-modified CacheIgnoreNoLastMod On CacheIgnoreCacheControl On # the origin server define cache-control: private, no-store only for user agents # Therefore, I would like ignore those headers on the proxy server. CacheStorePrivate On CacheStoreNoStore On CacheEnable disk / CacheRoot "C:/Apache.Cache" CacheDirLevels 5 CacheDirLength 4 CacheMinExpire 15 CacheDetailHeader on CacheHeader on KeepAlive Off ProxyPass / http://origin.lo/ ProxyPassReverse / http://origin.lo/ Also, I have turned on debug log level to see how mod_cache handles a content for caching: I provided this to show that mod_proxy always decides that a content isn't fresh. Why?I provided this to show that mod_proxy always decide that a content isn't fresh. Why? max-age was provided (see below).

• Apache2 graceful restart stops proxying requests to passenger

  Issue with apache mod proxy, it stops proxying requests after a graceful restart but not all the time. It seems to happen only on a Sunday when a graceful restart is triggered by logrotate.

• Deploying Django on EC2 using Bitnami Djangostack: WSGI script cannot be loadded

  - by Arman

  I've been struggling to deploy Django application on Amazon EC2 using Bitnami Djangostack for the last couple of days. When I go to http://dewey.io I see the default bitnami page (/opt/bitnami/apache2/htdocs/index.html), however, when I open http://dewey.io/portnoy, I get 'Internal Server Error'. But it's known that if mod_wsgi is setup correctly, the DocumentRoot value from httpd.conf is ignored, thus, I should see my Django application when accessing http://dewey.io. Essentially, the main error is this - 'Target WSGI script cannot be loaded as Python module'. Two questions: 1) any ideas how to fix these mod_wsgi errors (the Apache logs are below)? 2) how to disable the default /opt/bitnami/apache2/htdocs/index.html page and show my homepage from django application when accessing http://dewey.io? Thank you in advance! The details On my EC2 instance I"m running 64-bit Ubuntu 12.04 with DjangoStack 1.4-1.

• PASS: The Legal Stuff

  - by Bill Graziano

  I wanted to give a little background on the legal status of PASS.  The Professional Association for SQL Server (PASS) is an American corporation chartered in the state of Illinois.  In America a corporation has to be chartered in a particular state.  It has to abide by the laws of that state and potentially pay taxes to that state.  Our bylaws and actions have to comply with Illinois state law and United States law.  We maintain a mailing address in Chicago, Illinois but our headquarters is currently in Vancouver, Canada. We have roughly a dozen people that work in our Vancouver headquarters and 4-5 more that work remotely on various projects.  These aren’t employees of PASS.  They are employed by a management company that we hire to run the day to day operations of the organization.  I’ll have more on this arrangement in a future post. PASS is a non-profit corporation.  The term non-profit and not-for-profit are used interchangeably.  In a for-profit corporation (or LLC) there are owners that are entitled to the profits of a company.  In a non-profit there are no owners.  As a non-profit, all the money earned by the organization must be retained or spent.  There is no money that flows out to shareholders, owners or the board of directors.  Any money not spent in furtherance of our mission is retained as financial reserves. Many non-profits apply for tax exempt status.  Being tax exempt means that an organization doesn’t pay taxes on its profits.  There are a variety of laws governing who can be tax exempt in the United States.  There are many professional associations that are tax exempt however PASS isn’t tax exempt.  Because our mission revolves around the software of a single company we aren’t eligible for tax exempt status. PASS was founded in the late 1990’s by Microsoft and Platinum Technologies.  Platinum was later purchased by Computer Associates. As the founding partners Microsoft and CA each have two seats on the Board of Directors.  The other six directors and three officers are elected as specified in our bylaws. As a non-profit, our bylaws layout our governing practices.  They must conform to Illinois and United States law.  These bylaws specify that PASS is governed by a Board of Directors elected by the membership with two members each from Microsoft and CA.  You can find our bylaws as well as a proposed update to them on the governance page of the PASS web site. The last point that I’d like to make is that PASS is completely self-funded.  All of our $4 million in revenue comes from conference registrations, sponsorships and advertising.  We don’t receive any money from anyone outside those channels.  While we work closely with Microsoft we are independent of them and only derive a very small percentage of our revenue from them.

• Bitlocker and SQL Server (2012)

  - by cdonner

  I just turned on Bitlocker on my development laptop for the first time (Windows 8.1) and encrypted both SSDs. When I started SQL Server Enterprise Manager, it could not connect to the default instance on the local machine. Does this not work? I have been googling for an hour and only found anecdotal evidence, but no solid information. Just to clarify - I am not interested in encrypting a database. I want to run SQL Server on a machine with an encrypted drive.

• Server 2012, Jumbo Frames - should I expect problems?

  - by TomTom

  Ok, this sound might stupid - but is there any negative on just enabling jumbo frames in practice? From what I understand: Any switch or ethernet adapter that sees a jumbo frame it can not handle will just drop it. TCP is not a problem as max frame size is negotiated in the setinuo phase. UCP is a theoretical problem as a server may just send a LARGE UDP packet that gets dropped on the way. Practically though, as UDP is packet based, I do not really think any software WOULD send a UDP packet larger than 1500 bytes net without app level configuration changes - at least this is how I do my programming, as it is quite hard to get a decent MTU size for that without testing yourself, so you fall back in programming to max 1500 packets. The network in question is a standard small business network - we upgraded now from a non managed 24 port switch to a 52 port switch with 4 10g ports (netgear - quite cheap) and will mov a file server to 10g for also ISCSI serving. All my equipment on the Ethernet level can handle minimum 9000 bytes and due to local firewalls I really want to get packets larger (less firewall processing), but the network is also NAT'ed to the internet. On top, different machines move around (download) large files (multi gigabyte area) quite often for processing. The question is - can I expect problems when I just enable jumbo frames? Again, this is not totally ignorance - I just don't see programs sending more than 1500 byte UDP packets (if that is a practical problem please tell me) and for TCP the MTU is negotiated anyway. if there is a problem I can move to a dedicated VLAN, but this has it's own shares of problems as basically most workstations must then be on both VLAN's.

• Start jade via batch script as service on windows server 2012 amazon ec2 instance

  - by E. Lüders

  I would like to start the Jade agent platform with a batch script on an windows server ec2 instance as a service. The reason for this is, that I want to start jade automatically at system startup. For creating the service I use nssm. However so far its working fine and the service is created. When I want to start the service I get an error message: Windows could not start the NAME service on Local Computer. The service did not return an error... My batch file contains only one line: java jade.Boot -platform-id P%random% If i execute the script via cmd it works fine. Anybody got an idea why this is not working if I start the batch script as a service?

• Can Ping but Cannot Telnet directly to SQL Server 2012 Cluster Nodes

  - by tresstylez

  We have a monitoring tool (Solarwinds Orion) that needs to connect to a 2-node failover SQL Server Cluster. For reasons outside of our control -- we cannot monitor the CLUSTER IP directly at this time, so we have fallen back to monitoring each cluster node IP directly. This is not working. Upon troubleshooting, we tried to test that the cluster node was listening on the proper (fixed) port by using telnet to the cluster node IP/port -- and the telnet failed. However, telnet'ing to the Cluster IP/Port was SUCCESSFUL! Each node has its own IP. Each node is listening on the identical FIXED port. Each node has Dynamic Ports disabled. Each node can be PINGED successfully from the monitoring tool. Windows Firewall is DISABLED. How can I troubleshoot why I cannot telnet to the listening port on the cluster nodes?

• Symantec Backup exec 2012 for SBS - moving data to offsite drives

  - by Will Lennard

  Can anyone advise how best to run the following strategy, or even if it is possible/sensible strategy? I am looking to backup an SBS server using BE2012 where the data is backed up on a weekly full backup, with subsequent daily incrementals till the end of the week, a fresh full backup will then be taken the next weekend, and the cycle repeats for 4 weeks, thus 4 full backups with incrementals. This months worth of backups will then be moved off to an offsite store via USB drive for safe keeping. Is this viable, sensible, or am i just a bit crazy? All ideas are welcome.

• No compatibility tab for Devenv.exe (VS 2010 and VS 2012) on Windows 8

  - by mkinkade

  I've tried checking the "Run as Administrator" on the shortcut, but that doesn't always seem to work, like when I open the solution through the jumplist. I browsed to the devenv.exe file, but when I open the properties for the file the Compatibility tab is not there. It is there for other executables in the same directory. Does anyone know how I can get the tab back so that I can set the Run as Administrator open on the executable?

• Microsoft Deployment Toolkit 2012 Error

  - by Jacob Schaer

  I just started with MDT2012 recently in hopes of eventually getting away with using Ghost to deploy all of our department computers. When I test deploy in VirtualBox, it deploys the OS properly, but stops because of a network driver failure (it gets the "could not allocate resources" issue). On physical hardware (Latitude E6500, Optiplex 980, and an older Latitude) it gets through the multicast and stops immediately after with: "Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information" I've looked at the logs and never see anything really of note. Originally I was using DriverPacks from DriverPacks.net, but thinking it was a driver issue, I switched over to using Dell's cab driver packs. Still the same issue. I check and it did the HDD is all fine - it was properly partitioned, set to bootable, and was loaded with all the proper OS installer files. I'm using a flash drive to do the install - when I make changes to the deployment share I rebuild and copy the ISO to the drive, then use YUMI multiboot to start the ISO (probably irrelevant).

• HP DL380 G3 2U For Basic Web Server in 2012

  - by ryandlf

  I have an opportunity to pick up a used HP DL380 G3 2U for $100. I'm looking for a basic entry level web server that I can host a small - medium size website on and more or less learn the ins and outs of running my own web server before I bite the bullet and spend a couple grand on a server. The specs are: Dual (2) Intel Xeon 2.4GHz 400MHz 512KB Cache 4GB PC2100 ECC Registered Memory 6 x 72GB 10K U320 SCSI Hard Drives Smart Array 5i RAID Controller Redundant Power Supplies DVD/Floppy, Dual Intel GB NIC's, USB Or would I be better off spending a couple hundred bucks on something like: this new HP Seems like the only major difference is SATA and a bit of storage, but I will likely be implementing a separate storage system of some sort anyways. I guess it also wouldn't hurt to mention that I plan on running a linux server distro, so would the hardware be likely to support linux with a system that is 4 generations old? I don't mind spending a couple hundred extra dollars if its a better solution, but as mentioned previously I am simple looking for a server to learn on and probably use for a year or so while I put together a small - medium size website.

• Windows 2012 Master & Ubuntu Bind 9 Slave & SOA

  - by RecentCoin

  I'm kinda like the maid... I don't do Windows. But thanks to new things we're implementing, I'm now attempting replicating a single zone from our AD cluster. We had this working just fine but someone had to "adjust" it. That broke the replication completely. We've gotten that restarted but now a different DC is showing as the SOA. Does it matter which of the domain controllers is listed as the SOA? The contents of the zone file appear to be correct. Part of me says "Good enough. Leave it be." but the rest of me doesn't want a 3AM phone call. So does anyone know if it matters which DC is listed as the SOA?

• The reasons to upgrade from Delphi 2009

  - by Serg

  I have made the question "community wiki" - it is subjective. I have upgraded to Delphi 2009 because of unicode support. I have found the anonymous methods a very interesting and useful language feature, I can't say the same about generics. The generics seemed important for me before the upgrade to Delphi 2009, but I have never used them and probably will never use. As for Delphi 2010, I don't need the attributes and I don't like the whole idea of extended RTTI - that is why Delphi 2009 is better for me. Sometimes I hit one or other annoying bug in Delphi 2009 IDE, but they are not critical and I can live with them. I have no plans to develop software for Mac or Linux. Sure sometime I will need 64-bit support, so I think about upgrading to Delphi 2012. Are where any more reasons that can force me to upgrade from Delphi 2009?
