• Java Cloud Service for developers

  - by JuergenKress

  The advent of cloud computing has reinvented application development for many companies. “That’s the beauty of the cloud,” says Cameron Purdy, vice president of development, Oracle. “It dramatically improves developer productivity because they can do what they do best without having to manage complex development, testing, staging, and production environments.” The key is to find a platform that doesn’t impose proprietary restrictions or force developers to learn new tools. For example, Oracle Java Cloud Service is an enterprise-grade platform as a service for building and deploying Java EE, Oracle WebLogic Server, and Oracle Application Development Framework (Oracle ADF) applications. “It’s designed to be flexible and easy to use,” says Purdy. “And it is also a standards-based solution -it’s not proprietary and there is no cloud lock-in. Developers get instant access to an enterprise-grade environment for a simple, monthly subscription.” Oracle Java Cloud Service instances are created with just a few clicks, so businesses can create a rich application development environment within minutes. Running on Oracle WebLogic Server and Oracle Exalogic, the underlying infrastructure also leverages Oracle Fusion Middleware’s integration with common services. For example, instances come integrated and preconfigured with optimized Oracle Database and Oracle Identity Management configurations. Based on Oracle Enterprise Manager, the Oracle Java Cloud Service console lets customers easily manage and monitor their Oracle Java Cloud Service instances. The open nature of the Oracle Java Cloud Service lets developers integrate through Web services such as SOAP and REST APIs, as well as use their favorite developer tools, whether they are out-of-the-box tools such as Maven and Ant or the productivity features built into Oracle JDeveloper, Oracle Enterprise Pack for Eclipse, or NetBeans IDE. The service allows for the seamless movement of applications between on-premise Oracle WebLogic Server domains and instances of Oracle Java Cloud Service within Oracle Cloud. This approach allows flexibility to mix and match the use of on-premise environments with cloud instances for development, test, and production environments.

• rotating an object on an arc

  - by gardian06

  I am trying to get a turret to rotate on an arc, and have hit a wall. I have 8 possible starting orientations for the turrets, and want them to rotate on a 90 degree arc. I currently take the starting rotation of the turret, and then from that derive the positive, and negative boundary of the arc. because of engine restrictions (Unity) I have to do all of my tests against a value which is between [0,360], and due to numerical precision issues I can not test against specific values. I would like to write a general test without having to go in, and jury rig cases //my current test is: // member variables public float negBound; public float posBound; // found in Start() function (called immediately after construction) // eulerAngles.y is the the degree measure of the starting y rotation negBound = transform.eulerAngles.y-45; posBound = transform.eulerAngles.y+45; // insure that values are within bounds if(negBound<0){ negBound+=360; }else if(posBound>360){ posBound-=360; } // called from Update() when target not in firing line void Rotate(){ // controlls what direction if(transform.eulerAngles.y>posBound){ dir = -1; } else if(transform.eulerAngles.y < negBound){ dir = 1; } // rotate object } follows is a table of values for my different cases (please excuse my force formatting) read as base is the starting rotation of the turret, neg is the negative boundry, pos is the positive boundry, range is the acceptable range of values, and works is if it performs as expected with the current code. |base-|-neg-|-pos--|----------range-----------|-works-| |---0---|-315-|--45--|-315-0,0-45----------|----------| |--45--|---0---|--90--|-0-45,54-90----------|----x----| |-135-|---90--|-180-|-90-135,135-180---|----x----| |-180-|--135-|-225-|-135-180,180-225-|----x----| |-225-|--180-|-270-|-180-225,225-270-|----x----| |-270-|--225-|-315-|-225-270,270-315-|----------| |-315-|--270-|---0---|--270-315,315-0---|----------| I will need to do all tests from derived, or stored values, but can not figure out how to get all of my cases to work simultaneously. //I attempted to concatenate the 2 tests: if((transform.eulerAngles.y>posBound)&&(transform.eulerAngles.y < negBound)){ dir *= -1; } this caused only the first case to be successful // I attempted to store a opposite value, and do a void Rotate(){ // controlls what direction if((transform.eulerAngles.y > posBound)&&(transform.eulerAngles.y<oposite)){ dir = -1; } else if((transform.eulerAngles.y < negBound)&&(transform.eulerAngles.y>oposite)){ dir = 1; } // rotate object } this causes the opposite situation as indicated on the table. What am I missing here?

• Data Source Use of Oracle Edition Based Redefinition (EBR)

  - by Steve Felts

  Edition-based redefinition is a new feature in the 11gR2 release of the Oracle database. It enables you to upgrade the database component of an application while it is in use, thereby minimizing or eliminating down time. It works by allowing for a pre-upgrade and post-upgrade view of the data to exist at the same time, providing a hot upgrade capability. You can then specify which view you want for a particular session.  See the Oracle Database Advanced Application Developer's Guide for further information. There is also a good white paper at Edition Based Definition. Using this feature of the Oracle database does not require any new WebLogic Server functionality. It is set for each connection in the pool automatically by simply specifying SQL ALTER SESSION SET EDITION = edition_name in the Init SQL parameter in the data source configuration. This can be configured either via the console or via WLST (setInitSQL on the JDBCConnectionPoolParams). This SQL statement is executed for each newly created physical database connection.Note that we are assuming that a data source references only one edition of the database. To make use of this feature, you would have an earlier version of the application with a data source that references the earlier EDITION and a later version of the application with a data source that references the later EDITION.   Once you start talking about multiple versions of a WLS application, you should be using the WLS "side-by-side" or "versioned" deployment feature.  See Developing Applications for Production Redeployment for more information.  By combining Oracle database EBR and WLS versioned deployment, the application can be failed over with no downtime, making the combination of features more powerful than either independently. There is a catch - you need to be running with a versioned database and a versioned application initially so then you can switch versions.  The recommended way to version a WLS application is to simply add the "Weblogic-Application-Version" property in the MANIFEST.MF file(you can also specify it at deployment time). The recommended way to configure the data source is to use a packaged data source descriptor that's stored in the ear or war so that everything is self-contained.  There are some restrictions.  You can't use a packaged data source with Logging Last Resource (LLR) - you need to use a system resource.  You can't use an application-scoped packaged data source with EmulateTwoPhaseCommit for the global-transactions-protocol with a versioned application - use a global scope.  See Configuring JDBC Application Modules for Deployment for more details. There's one known problem - it doesn't work correctly with an XA data source (patch available with bug 14075837).

• Should I use my own public API on my site (via JS)?

  - by newboyhun

  First of all, this question is far more different other 'public api questions' like this: Should a website use its own public API?, second, sorry for my English. You can find the question summarized at the bottom of this question. What I want to achieve is a big website with a public api, so who like programming (like me) and likes my website, can replicate my website's data with a much better approach (of course with some restrictions). Almost everything could be used by the public API. Because of this, I was thinking about making the whole website AJAX driven. There would be parts of the API which would be limited only to my website (domain), like login, registering. There would be only an INTERFACE on the client side, which would use the public and private API to make this interface working. The website would be ONLY CLIENT SIDE, well, I mean, the website would only use AJAX to use the api. How do I imagine this? The website would be like a mobile application, the application only sending a request to a webserver, which returns a json, the application parses it, and uses it to advance in the application. (e.g.: login) My thoughts: Pros: The whole website is built up by javascript, this means I don't need to transfer the html to the client, saving bandwidth. (I hope so) Anyone can use up the data of my website to make their own cool things. (Is this a con or pro? O_O) The public API is always in use, so I can see if there are any error. Cons: Without Javascript the website is unusable. The bad guys easily can load the server with requesting too much data (like Request Per Second 10000), but this can be countered via limiting this with some PHP code and logging. Probably much more work So the question in some words is: Should I build my website around my own api? Is it good to work only on the client side? Is this good for a big website? (e.x.: facebook, yeah facebook is a different story, but could it run with an 'architecture' like this?)

The sql works select * from ebigusertim where id='blah'. It returns 2 distinct rows. When i query the data using hibernate, it appears that the object memory is not being allocated for each entry in the list. Thus, i get 2 entries in the list with the same object. Criteria userCriteria = session.createCriteria(EbigUser.class); userCriteria.add(Restrictions.eq("id", id)); userlist = userCriteria.list();

• TortoiseSVN hangs in Windows Server 2012 Azure VM

  - by ZaijiaN

  Following @shanselman's article on remoting into an Azure VM for development, I spun up my own VS 2013 VM, and that image runs on WS 2012. Once I was able to remote in, I started installing all my dev tools, including Tortoise SVN 1.8.3 64bit. Things went south once I started attempting to check out code from my personal svn server. It would hang and freeze often, although sometimes it would work - I was able to partially check out projects, but I would get frequent connection time out errors. My personal svn server (VisualSVN 2.7.2) runs at home on a windows 7 machine, and I have a dyndns url pointing to it. I have also configured my router to passthrough all 443 traffic to the appropriate port on the server. I self-signed a cert and made sure it was imported into the VM cert store under trusted root authorities. I have no problems connecting to my svn server from 4-5 other computers & locations. From the Azure VM, in both IE and Chrome, I can access the repository web browser with no issues. There are no outbound firewall restrictions. I have installed other SVN add-ons for Visual Studio (AnkhSVN, VisualSVN) and attempted to connect with my svn server, with largely the same results - random and persistent connection issues (hangs/timeouts). I spun up a completely fresh WS 2008 Azure VM, and installed TortoiseSVN, and had the same results. So I'm at a loss as to what the problem is and how to fix it. Web searches on tortoisesvn and windows server issues doesn't yield any current or relevant information. At this point, i'm guessing that maybe some setting or configuration that MS Azure VM images is the culprit - although I should probably attempt to spin up my own local WS VM to rule out that it's a window server issue. Any thoughts? I hope I'm just missing something really obvious!

• Configuring external SMTP server on Azure VM - messages staying in queue

  - by Steph Locke

  I have an external SMTP provider: auth.smtp.1and1.co.uk I am trying to send SQL Server Reporting Services emails via this on an Windows 2012 Azure VM. It is configured sufficiently correctly for emails to be generated, but I've not configured something or mis-configured something as the emails then stay in the queue. Setup details Configured SMTP Virtual Server General: IP Address: Fixed value Access: Access Control: Authentication: ticked Anonymous access Access: Connection Control: All except the list below (which is empty) Access: relay restrictions: Only the list below (which contains 127.0.0.1), ticked 'allow all..' option Delivery: Outbound Security...:Basic Authentication with username and password completed, ticked TLS encryption Delivery: Outbound connections...:TCP port=587 Delivery: Advanced: FQDN=ServerName, smarthost=auth.smtp.1and1.co.uk I then set the following SSRS rsreportserver.config values: <SMTPServer>100.92.192.3</SMTPServer> <SendUsing>2</SendUsing> <SMTPServerPickupDirectory> c:\inetpub\mailroot\pickup </SMTPServerPickupDirectory> <From>[email protected]</From> Tried so far 1) turning the smtp service off and on again (just in case) 2) run SMTPDiag with no errors (also no emails) 3) tried turning off the firewall for the ports (and more generally to see if it made a difference) 4) tried generation from powershell which resulted with message in queue 5) added 25 and 857 as endpoint 6) perused the event log and found some warnings that appear to be about the recipient Message delivery to the remote domain 'gmail.com' failed for the following reason: Unable to bind to the destination server in DNS. Message delivery to the host '212.227.15.179' failed while delivering to the remote domain 'gmail.com' for the following reason: The remote server did not respond to a connection attempt. 7) tried pinging but this appears to be blocked on azure 8) tried more powershell sending on different domains variants (localhost, boxname, internal ip used in smtp properties, 127.0.0.1) - none resulting in success 9) tried adding a remote domain - no change Could anyone recommend what step 10 should be in fixing this issue please?

• Adding an user to samba

  - by JustMaximumPower

  I'm trying to setup some samba shares in my home network on an Ubuntu 12.04 machine. Everything works fine for my user account (max) but I can not add any new user. Every time I try to add new user they can not use the shares. It's likely that the error is very basic to the concept of samba but please don't just tell me to read the docs. I've been trying that for about 2 weeks now. I've set up the server with my user max who can mount transfer and the share max. Than I added the user simon with sudo adduser --no-create-home --disabled-login --shell /bin/false simon because the user should not be able to ssh into the machine. I did an sudo smbpasswd -a simon and set an (samba) password for simon and added an share for simon. I also added simon to transferusers to give him access to the share transfer. But simon can't connect to transfer or simons. ---- output of testparam: ------- Load smb config files from /etc/samba/smb.conf rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) Processing section "[printers]" Processing section "[print$]" Processing section "[max]" Processing section "[simons]" Processing section "[transfer]" Loaded services file OK.

• WebDav rename fails on an Apache mod_dav install behind NginX

  - by The Daemons Advocate

  I'm trying to solve a problem with renaming files over WebDav. Our stack consists of a single machine, serving content through Nginx, Varnish and Apache. When you try to rename a file, the operation fails with the stack that we're currently using. To connect to WebDav, a client program must: Connect over https://host:443 to NginX NginX unwraps and forwards the request to a Varnish server on http://localhost:81 Varnish forwards the request to Apache on http://localhost:82, which offers a session via mod_dav Here's an example of a failed rename: $ cadaver https://webdav.domain/ Authentication required for Webdav on server `webdav.domain': Username: user Password: dav:/> cd sandbox dav:/sandbox/> mkdir test Creating `test': succeeded. dav:/sandbox/> ls Listing collection `/sandbox/': succeeded. Coll: test 0 Mar 12 16:00 dav:/sandbox/> move test newtest Moving `/sandbox/test' to `/sandbox/newtest': redirect to http://webdav.domain/sandbox/test/ dav:/sandbox/> ls Listing collection `/sandbox/': succeeded. Coll: test 0 Mar 12 16:00 For more feedback, the WebDrive windows client logged an error 502 (Bad Gateway) and 303 (?) on the rename operation. The extended logs gave this information: Destination URI refers to different scheme or port (https://hostname:443) (want: http://hostname:82). Some other Restrictions: Investigations into NginX's Webdav modules show that it doesn't really fit our needs, and forwarding webdav traffic to Apache isn't an option because we don't want to enable Apache SSL. Are there any ways to trick mod_dav to forward to another host? I'm open to ideas :).

• Does any Certificate Authority support both SAN and wildcards?

  - by nicholas a. evans

  My basic quandry is that wildcard certificates don't support subdomains of subdomains, nor do they help with alternate domain names. Basically, if my CN is example.com, I want a Subject Alternative Name field that looks roughly like so: DNS:example.com DNS*.example.com DNS:*.beta.example.com DNS:example.net DNS:*.example.net DNS:*.beta.example.net Using a self-signed cert, I verified that the browsers will work just fine with this. Unfortunately, none of the Certificate Authorities that I looked into (Thawte, GoDaddy, Verisign, Digicert) seemed to support both wildcard certs and Subject Alternative Name (sometimes referred to as "Multiple Domain UCC"). I even called up GoDaddy tech support to confirm. Is there a CA (trusted by 99% of browsers) that supports wildcards for the Subject Alternative Name? One little restriction: I'm saddled with Amazon EC2's single Elastic IP per instance limitation. Here are what I see as my backup plans: set up three extra EC2 instances, each configured for a different IP address and cert, and nginx reverse proxy from three of them into the app server(s) introduces latency(?), and even the cheapest EC2 instance isn't that cheap instead of dedicated reverse proxy instances, setup the four or more almost identical EC2 app servers, with nginx using the port to determine which cert to deliver, and use haproxy to distribute the traffic amongst themselves. complicated to configure and manage? I'm not using the cheapest EC2 instance type for my app servers. If I don't need 4+ app servers for the load, it raises the cost. set up an external server (outside of EC2) that doesn't have EC2's Elastic IP address restrictions, setup all of the alternate IP addresses and certificates on that server, and nginx reverse proxy from that server into the EC2 app servers. extra IP addresses are almost free (still need to pay for the server of course), but don't come with the robust "elasticity" that Amazon's Elastic IPs provide. even more latency than in the first scenario. Are these approaches crazy or reasonable? Do you have another one to suggest?

• Mac Management and Security

  - by Bart Silverstrim

  I was going through some literature on managing OS X laptops and asked someone some questions about usage scenarios when using the MacBooks. I asked someone more knowledgeable than I about whether it was possible for my Mac to be taken over if I were visiting another site for a conference or if I went on a wifi network at a local coffee house with policies from an OS X Server with workgroup manager (either legit for the site or someone running a version of OS X Server on hardware they have hidden somewhere on the network), which apparently could be set up to do things like limit my access to Finder or impose other neat whiz-bang management features. He said that it is indeed possible for it to happen as it would be assigned via the DHCP server and the OS X server would assume my Mac is a guest and could hand out restrictions and apparently my Mac will happily accept them without notifying me or giving me an option, unlike Windows which I believe would need to be joined to a domain before it becomes "managed" by Active Directory. So my question is as network admins and sysadmins with users traveling with MacBooks, is there a way to reasonably protect your users from having their machines hijacked without resorting to just turning off networking all the time? Or isn't this much of a security hazard? What threat does this pose to the road warriors in your businesses?

  I'm having trouble setting up the appropriate Pure-FTPD accounts and permissions - I have the following sites setup up on my Debian server. /var/www/site1 /var/www/site2 /var/www/wordpress The permissions are 775 for folders and 664 for files. The owner is currently admin:ftpgroup Wordpress also requires special permissions for file uploads in /var/www/wordpress/wp-content/uploads What I need is: a general admin group with access to /var/www a group for each site (site1, site2, wordpress) and a group or user, not www-data (?), with permissions to write files to the wordpress upload folder I ask because restrictions on linux groups (can't have groups in groups) makes it a little bit confusing and also because many of the tutorial sites have conflicting information like, some recommend the use of www-data and some don't. Also, I'm not sure if I understand how Pure-FTP is supposed to work exactly. I create a Pure-FTPD account and assign it a directory (/var/www) and a system user (ftpuser) and group (ftpgroup): Can I assign more than 1 path? For example, if a user requires access to 2 sites. Is it better to assign ftpgroup to all ftp locations and let Pure-FTPD manage account access? Why would anyone have more than 1 ftpuser or ftpgroup? (Doesn't it mean users have access to everyone else's files if they could get there?) Sorry for so many questions at once. I've been reading lots of tutorials but I think they've ended up making me more confused!

• Missing Home Folder XP Clients 2008R2 Domain

  - by minamhere

  We just completed a migration from Server 2003 to Server 2008R2. Everything seems to have gone well except that many of our desktops have stopped mapping the Home Folder as set in Active Directory. Other mappings that are defined on individual clients are mapping just fine, these mappings are all on the same file server as the failing Home Folders. Half of the users are on 1 file server and half are on another. Users from both servers are having this problem. I have enabled the Group Policy setting to "Wait for network before logging in". I enabled the policy to "Run Logon Scripts synchronously". There are no errors on the Domain Controller or either File Server. When I enabled Group Policy Preferences as an attempted workaround, I get this error: The user 'V:' preference item in the '<Policy Name>' Group Policy object did not apply because it failed with error code '0x800708ca This network connection does not exist.' This error was suppressed. This seems to indicate that the network connection is not ready by the time Group Policy is processed. But isn't this the point of the "Wait before logging in" and "Run Logon scripts synchronously" settings? Some other background facts: The new Server 2008R2 installation is a Virtual Machine. It is on a new Subnet in a different building from the old server. DNS and DHCP were also migrated from the old DC to this new DC. These Home Folders were all working properly before the migration. Are there new security restrictions/policies in Server 2008R2 that might be causing this? Is there a way to check whether I have an underlying network connectivity issue? Maybe moving the server to the new building is causing a delay/timeout? Any thoughts or ideas on what could be causing this or how I can resolve this? Thanks.

• access an IP restricted service from a dynamic IP (Broadband modem) on a windows machine

  - by Joel Alenchery

  Hi, I dont know if this is the correct place to ask this question but here goes .. (please note that I am pretty much a newbie in terms of networking and I work primarily on the windows platform) I have been working on accessing and consuming some web services in C#/ASP.Net, these web services that I consume are IP restricted. Currently they allow access only from my work network (we have a static ip set up through which all our internet requests are routed). Every now and then we have people who go out and about and are stuck with using a usb dongle based internet connection and hence are not able to now access these web services that they are working on. What I would like to do is to provide some way for these remote workers to access the IP restricted web services using the static ip at our office. For example when the remote worker tries to access a service say http://exampleService.com .. the request gets routed to some box at our office and then out to the actual service. That way the service always sees the static ip of the office and not the dynamic ip that the remote user is actually using. I have done a fair bit of googling and its difficult to search for it as most of the results come back for dynamic DNS which is not really what I am looking for. I have also looked at a couple of posts on here namely Accessing IP restricted server from dynamic IP which does provide some insight but the fellow seems to have access to the source that does the ip restriction and is able to change the restrictions. In my case i dont have that access. another one that looked interesting was Static IP for dynamic IP the first answer seems exactly what I need but I dont know how I would go about doing the same on a windows machine. any help would be really appreciated. (am sorry about being soo noob-ish) PS: Right now everyone is using RDC/LogMeIn to access an internet connected machine in the office to manually check the webservice and getting work done. Which is a very tedious process.

• How to connect the virtual networks of vmware guests running on different hosts?

  - by gyrolf

  In a test setup, we are running several virtual machines on a single vmware workstation host. All virtual machines are connected via a "host only" network. This runs fine up to 2 or 3 virtual machines (depending on the host hardware). To allow more virtual machines, we want to use more host machines. Details about the environment and applications: Host PCs are running Windows XP in a corporate intranet. VMware used is Workstation 6.5 Guests are running Windows Server 2003 All guests act as Web Servers One of the guests additionally acts as Windows File server, offering shared folders for the other guests to connect to. Restrictions: VMware guests shall not be visible from the intranet. Changes to the host PC are restricted by corporate policy. In the virtual network, no domain controller exists. All virtual machines are member of the same workgroup. Running the virtual network as NAT is possible. Port forwarding might be used if it does not conflict with ports used by the host PC. Looking for a solution, I found hints about using router or vpn software on the hosts, but without any details how to setup. (I found a similar question Sharing the network between 2 VMware hosts, but the answer was not sufficient for me.)

• Mac Management Without Permission and Security

  - by Bart Silverstrim

  I was going through some literature on managing OS X laptops and asked someone some questions about usage scenarios when using the MacBooks. I asked someone more knowledgeable than I about whether it was possible for my Mac to be taken over if I were visiting another site for a conference or if I went on a wifi network at a local coffee house with policies from an OS X Server with workgroup manager (either legit for the site or someone running a version of OS X Server on hardware they have hidden somewhere on the network), which apparently could be set up to do things like limit my access to Finder or impose other neat whiz-bang management features. He said that it is indeed possible for it to happen as it would be assigned via the DHCP server and the OS X server would assume my Mac is a guest and could hand out restrictions and apparently my Mac will happily accept them without notifying me or giving me an option, unlike Windows which I believe would need to be joined to a domain before it becomes "managed" by Active Directory. So my question is as network admins and sysadmins with users traveling with MacBooks, is there a way to reasonably protect your users from having their machines hijacked without resorting to just turning off networking all the time? Or isn't this much of a security hazard? What threat does this pose to the road warriors in your businesses?

• Windows 7 Users unable to add Windows 2003 server printers

  - by TravBrack

  Hi there I just rolled out a few Windows 7 x64 machines and ran into this issue where non-admin users are unable to add printers hosted on a windows 2003 server. It works fine on a 2008 server. The issue appears to be with the point and print system. A user will attempt to add the printer, a prompt will come up requiring the user to elevate privileges in order to install a driver, and will fail citing 'access denied'. I found the group policy setting Point and Print Restrictions: When the policy setting is disabled: -Windows Vista computers will not show a warning or an elevated command prompt when users create a printer connection to any server using Point and Print. So I disabled it, verified that the policy was being picked up using rsop, but it still does the same thing. I've also tried the following: Recreating the printers using newer drivers Adding the printer using 32 bit drivers on the 2003 machine, then adding the 64 bit drivers on a Windows 7 machine Adding the printer from a windows 7 machine using print management None of these things work. The security settings are no different than the working printers. Help?

• How do I prevent or override a group policy on Windows 7?

  - by Kevin

  A few months ago my company was purchased by a large corporation. We recently switched our network over to the large corporate network which has more restrictions requirements. One of these is the requirement to use a proxy server for Internet traffic. However, some of our internal servers are not recognized by the corporate DNS, so we need to provide the fully qualified domain name. For W7, we make changes to the Internet Properties for IE8 and Chrome to include our domain name as an exception to the proxy server (e.g., *.foobar.com). The problem is that a group policy that does not include our domain name is continually pushed out to my systems throughout the day. This requires me to make the appropriate changes to the Internet Properties several times a day in order to access our internal servers. Is there a way that I can prevent the group policy from being pushed to my systems or detect when the group policy is pushed and override it? I am an administrator on all of my systems. I do have Firefox installed which is not subject to the same group policy push, but I need to have IE8 and Chrome working.

• Windows 7 - How to access my documents from Windows 8 (dual boot)

  - by msbg

  I am dual booting Windows 7 and Windows 8 on two different partitions of the same drive: Win7: (C:) Win8: (D:) I am trying to get access to my Win7 user folder (C:\Users\Mason) in order to access my Win7 documents folder (C:\Users\Mason\Documents) from Windows 8. When I try to on Windows 8, I get an error message saying "You don't have permission to access this folder. Click here to permanently get access to this folder". When I click, the progress bar in Windows Explorer slowly moves to the maximum and disappears. When I try opening the folder, I get the same error message. When editing security permissions for the folder in Windows 8, Explorer freezes. I do not know how to remove the restrictions from Windows 7. I checked the Windows 8 user folder (D:\Users\Mason) and it had the group or user name: "S-1-5-21-936898901-3363470404-1273668825-1001". I tried copying and pasting it into the Win7 User Folder Permissions, but got the error "An object with the following name cannot be found". How would I access my folders?

• copying folder and file permissions from one user to another after switching domains [closed]

  - by emptyspaces

  Please excuse the title, this was the best way I could think to describe this scenario without an entire paragraph. I am using C#. Currently I have a file server running windows server 2003 setup on a domain, we will call this oldDomain, and I have about 500 user accounts with various permissions on this server. Because of restrictions out of my control we are abandoning this domain and using another one that is more dominant within the organization, we will call this newDomain. All of the users that have accounts on oldDomain also have accounts on newDomain, but the usernames are completely different and there is no link between the two. What I am hoping to do is generate a list of all user accounts and this appropriate sid's from AD on the oldDomain, I already have this part done using dsquery and dsget. Then I will have someone go through and match all of the accounts from oldDomain to the correct username on newDomain. Ultimately leaving me with a list of sids from oldDomain and the appropriate username from newDomain. Now I am hoping to copy the file and folder permissions from the old user from oldDomain to the new user on newDomain once I join the server to newDomain. Can anyone tell me what the best way to copy permissions from the sid to the user on newDomain? There are a bunch of articles out there about copying permissions from user a to user b but I wanted to check and see what the recommended practice is here since there are a ton of directories.

• Run command remotely on Windows computer

  - by Bilal Aslam

  I have a Windows Server 2008 instance on Amazon EC2 (Amazon's cloud compute platform, which provides VMs in the cloud). It has an external IP, and I have an admin account on the box. I would like to 'bootstrap' this instance remotely i.e. I want to run commands to download, install and configure apps on it, all without having to log on even once. Also, I cannot use psexec on the source computer. I have figured out how to do this to a remote, domain-joined computer using WMI. However, I have NOT been able to do for a remote computer on EC2. Here are some specific restrictions: The remote computer is not part of my domain, hence no Kerberos The remote computer does not have a cert I trust, or vice versa I am sure I am running into to some auth/trust restriction. Is there any way I can run a single command on the remote, given that I have admin privileges? I'm not tied down to using WMI, but I do need to run a command somehow. Feels like this should be a solved problem.
