• upgrade from windows 2008 server CORE to full windows 2008 server

  - by laurens

  Possible Duplicate: Install GUI on Windows Server 2008 Core As I've seen there is not really a topic about this here... My question: Is there any means to upgrade from windows 2008 server CORE to full windows 2008 server? The server is used as Hyper-V Host machine. On the internet mostly I find: "no you'll have to reinstall" But maybe there's a workaround? Thanks in advance

• Unable to Set Up Remote Access on Windows Home Server

  - by Matt Hanson

  When trying to turn on Remote Access on my Windows Home Server (HP MediaSmart Ex485, MediaSmart Server 3.0, Power Pack 3), I am not able to continue through the wizard as this first check fails: "Verifying that your remote Web site is available locally" Everything else on the server works fine, including being able to: Ping server RDP to server Access all shares as expected Browse to both http://servername and http://servername:55000 I have noticed though that I am unable to browse to http://servername:56000 as I should be able to do. I've performed a server recovery to reset the installation to factory defaults, with no such luck.

• in HFT trading should I upgrade from Windows Server 2008 R2 to Windows Server 2012?

  - by javapowered

  I'm using HP DL360p Gen8 + Windows Server 2008 R2 for HFT trading. That means that every 10 microseconds is important for me. I do understand that if I need everything to be so fast I probably should consider using Linux. But in this post I want to compare only Windows Server 2008 R2 and Windows Server 2012. I've found in internet couple articles that suggest how to tune Windows Server 2012 for low latency http://msdn.microsoft.com/library/windows/hardware/jj248719 http://technet.microsoft.com/en-us/library/hh831415.aspx Most part of optimizations from these articles apply only to Windows Server 2012 and can not be used on Windows Server 2008 R2. So now I think that as I can optimize Windows Server 2012 for low latency, probaly I should upgrade? After optimizations how much faster windows server 2012 would be (ideally in microseconds :)?

• DNS Server Order Incorrect on Windows 7 via PPTP VPN to Windows 2003 Server

  - by Simon

  Hi there. When I connect a Windows XP laptop via PPTP vpn to our Windows 2003 Server, the DNS Server order is correct: 192.168.8.3 208.67.222.222 208.67.220.220 But when I connect a Windows 7 laptop via PPTP VPN to our Windows 2003 Server, the DNS order is incorrect: 208.67.222.222 208.67.220.220 192.168.8.3 What do I need to do on our Windows 2003 Server to fix this so the when I do a ping, it will work correctly?

• Repercussions of Raising Domain Functional Level to 2008 on Mac computers running 10.6.2 with OD

  - by JohnyV

  We have recently replaced all of our 2003 server domain controllers to 2008 r2 and have tried to implement PSO's but have found that the domain functional level must be raised to 2008. We have a mac server in our environment that runs open directory and it is integrated into AD. Does anyone know if I do raise the domain functional level (which makes sense since we only have 2008 r2 domain controllers) what the repercussions (if any) there will be on the macs in the environment? Macs are running 10.6.2 and mac server runs the same. Mac server is running OD and also bound to AD.

• cannot at all find sql instance (while installing an asp.net app on IIS)

  - by giddy

  So I'm really not a DBA, I'm an app dev. I had to install my asp.net mvc3 app on my client's(a large company) IIS6 + Win2k3 machine, with absolutely no help from their sysadmins. The final problem now is SQL Server 2008 r2, after figuring out how to create a login from windows, my app and sqlcmd.exe always complains it cannot find a sql server instance!! I have all the sql services (in services.msc) running to Log On as the local system. I can login fine with SQL Server Management Studio with Windows Auth. I created my database, my asp.net app needs/uses windows auth. But for the love of God, whatever I do my app always complains it cannot find the instance. (Also tried running SQL CMD and it complains of the same thing too!) My data base connection string looks like this: Data Source=machinename\username;Initial Catalog=myDataStore;Integrated Security=True;MultipleActiveResultSets=True Machinename\user is the same thing that shows up on the sql server management studio login if I choose windows authentication right?

• Unable to connect to sharedfax error

  - by Owl

  I'm running SBS2k on a machine with a 56k modem for all outgoing faxes. We have a terminal server running server 2003 enterprise and in printers the sharedfax shows "unable to connect status". When you right-click, properties, it gives you an error saying the spool service is not running and you cannot view properties. The spooler service is indeed running on the 2k3 server because I can view the other printer's properties..and on 2k I show the Microsoft Shared Fax service AND Print Spooler as started. Here's the tricky part, I can add the shared fax printer on a domain computer locally (Windows XP) and it will show ready status and I can send faxes, they show up on the 2k server's fax console manager as in progress. I've sent a couple from a few different workstations today successfully, but still unable to send from 2k3 terminal services.

• Accessing Active Directory Role Membership through LDAP using SQL Server 2005

  - by David Neale

  I would like to get a list of Active Directory users along with the security groups they are members of using SQL Server 2005 linked servers. I have the query working to retrieve records but I'm not sure how to access the memberOf attribute (it is a multi-value LDAP attribute). I have this temporary to store the information: DROP TABLE #ADUSERGROUPS CREATE TABLE #ADUSERGROUPS ( sAMAccountName varchar(30), UserGroup varchar(50) ) Each group/user association should be one row. This is my SELECT statement: SELECT sAMAccountName,memberOf FROM OpenQuery(ADSI, '<LDAP://hqdc04/DC=nt,DC=avs>; (&(objectClass=User)(sAMAccountName=9695)(sn=*)(mail=*)(userAccountControl=512)); sAMAccountName,memberOf;subtree') I get this error msg: OLE DB error trace [OLE/DB Provider 'ADSDSOObject' IRowset::GetData returned 0x40eda: Data status returned from the provider: [COLUMN_NAME=memberOf STATUS=DBSTATUS_E_CANTCONVERTVALUE], [COLUMN_NAME=sAMAccountName STATUS=DBSTATUS_S_OK]].

• Auto Increment feature of SQL Server

  - by Rahul Tripathi

  I have created a table named as ABC. It has three columns which are as follows:- The column number_pk (int) is the primary key of my table in which I have made the auto increment feature on for that column. Now I have deleted two rows from that table say Number_pk= 5 and Number_pk =6. The table which I get now is like this:- Now if I again enter two new rows in this table with the same value I get the two new Number_pk starting from 7 and 8 i.e, My question is that what is the logic behind this since I have deleted the two rows from the table. I know that a simple answer is because I have set the auto increment on for the primary key of my table. But I want to know is there any way that I can insert the two new entries starting from the last Number_pk without changing the design of my table? And how the SQL Server manage this record since I have deleted the rows from the database??

• SQLAuthority News – SQL Server 2012 Upgrade Technical Guide – A Comprehensive Whitepaper – (454 pages – 9 MB)

  - by pinaldave

  Microsoft has just released SQL Server 2012 Upgrade Technical Guide. This guide is very comprehensive and covers the subject of upgrade in-depth. This is indeed a helpful detailed white paper. Even writing a summary of this white paper would take over 100 pages. This further proves that SQL Server 2012 is quite an important release from Microsoft. This white paper discusses how to upgrade from SQL Server 2008/R2 to SQL Server 2012. I love how it starts with the most interesting and basic discussion of upgrade strategies: 1) In-place upgrades, 2) Side by side upgrade, 3) One-server, and 4) Two-server. This whitepaper is not just pure theory but is also an excellent source for some tips and tricks. Here is an example of a good tip from the paper: “If you want to upgrade just one database from a legacy instance of SQL Server and not upgrade the other databases on the server, use the side-by-side upgrade method instead of the in-place method.” There are so many trivia, tips and tricks that make creating the list seems humanly impossible given a short period of time. My friend Vinod Kumar, an SQL Server expert, wrote a very interesting article on SQL Server 2012 Upgrade before. In that article, Vinod addressed the most interesting and practical questions related to upgrades. He started with the fundamentals of how to start backup before upgrade and ended with fail-safe strategies after the upgrade is over. He covered end-to-end concepts in his blog posts in simple words in extremely precise statements. A successful upgrade uses a cycle of: planning, document process, testing, refine process, testing, planning upgrade window, execution, verifying of upgrade and opening for business. If you are at Vinod’s blog post, I suggest you go all the way down and collect the gold mine of most important links. I have bookmarked the blog by blogging about it and I suggest that you bookmark it as well with the way you prefer. Vinod Kumar’s blog post on SQL Server 2012 Upgrade Technical Guide SQL Server 2012 Upgrade Technical Guide is a detailed resource that’s also available online for free. Each chapter was carefully crafted and explained in detail. Here is a quick list of the chapters included in the whitepaper. Before downloading the guide, beware of its size of 9 MB and 454 pages. Here’s the list of chapters: Chapter 1: Upgrade Planning and Deployment Chapter 2: Management Tools Chapter 3: Relational Databases Chapter 4: High Availability Chapter 5: Database Security Chapter 6: Full-Text Search Chapter 7: Service Broker Chapter 8: SQL Server Express Chapter 9: SQL Server Data Tools Chapter 10: Transact-SQL Queries Chapter 11: Spatial Data Chapter 12: XML and XQuery Chapter 13: CLR Chapter 14: SQL Server Management Objects Chapter 15: Business Intelligence Tools Chapter 16: Analysis Services Chapter 17: Integration Services Chapter 18: Reporting Services Chapter 19: Data Mining Chapter 20: Other Microsoft Applications and Platforms Appendix 1: Version and Edition Upgrade Paths Appendix 2: SQL Server 2012: Upgrade Planning Checklist Download SQL Server 2012 Upgrade Technical Guide [454 pages and 9 MB] Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: Database, DBA, PostADay, SQL, SQL Authority, SQL Documentation, SQL Download, SQL Query, SQL Server, SQL Tips and Tricks, SQL White Papers, SQLAuthority News, SQLServer, T SQL, Technology

• Is basing storage requirements based on IOPS sufficient?

  - by Boden

  The current system in question is running SBS 2003, and is going to be migrated on new hardware to SBS 2008. Currently I'm seeing on average 200-300 disk transfers per second total across all the arrays in the system. The array seeing the bulk of activity is a 6 disk 7200RPM RAID 6 and it struggles to keep up during high traffic times (idle time often only 10-20%; response times peaking 20-50+ ms). Based on some rough calculations this makes sense (avg ~245 IOPS on this array at 70/30 read to write ratio). I'm considering using a much simpler disk configuration using a single RAID 10 array of 10K disks. Using the same parameters for my calculations above, I'm getting 583 average random IOPS / sec. Granted SBS 2008 is not the same beast as 2003, but I'd like to make the assumption that it'll be similar in terms of disk performance, if not better (Exchange 2007 is easier on the disk and there's no ISA server). Am I correct in believing that the proposed system will be sufficient in terms of performance, or am I missing something? I've read so much about recommended disk configurations for various products like Exchange, and they often mention things like dedicating spindles to logs, etc. I understand the reasoning behind this, but if I've got more than enough random I/O overhead, does it really matter? I've always at the very least had separate spindles for the OS, but I could really reduce cost and complexity if I just had a single, good performing array. So as not to make you guys do my job for me, the generic version of this question is: if I have a projected IOPS figure for a new system, is it sufficient to use this value alone to spec the storage, ignoring "best practice" configurations? (given similar technology, not going from DAS to SAN or anything)

• Enterprise class storage best practices

  - by churnd

  One thing that has always perplexed me is storage best practices. Filesystems brag about how they can be petabytes or exabytes in size. Yet, I do not know many sysadmins who are willing to let a single volume grow over several terrabytes. I do know the primary reason behind this is how long it would take to rebuild the array should a drive fail. The more drives in a single LUN, the longer this takes and the greater your risk of losing another drive while the rebuild is taking place. Then there's usage reasons. Admins will carve out a LUN based on how much space they think needs to be allocated to the project. It seems more practical to me for the LUN to be one large array and to use quotas. I understand this wouldn't satisfy every requirement (iSCSI), but I see a lot of NAS systems (NFS) managed this way. I also understand that the underlying volumes can be grown/shrunk as needed quite easily, but wouldn't it be less "risky" to use quotas rather than manipulating volumes and bringing possible data loss into the equation? There may be some other reasons I'm missing, so please enlighten me. Can we not expect filesystems to ever be so large? Are we waiting for the hardware to get faster to cut down on rebuild times?

• How to diagnose storage system scaling problems?

  - by Unknown

  We are currently testing the maximum sequential read throughput of a storage system (48 disks total behind two HP P2000 arrays) connected to HP DL580 G7 running RHEL 5 with 128 GB of memory. Initial testing has been mainly done by running DD-commands like this: dd if=/dev/mapper/mpath1 of=/dev/null bs=1M count=3000 In parallel for each disk. However, we have been unable to scale the results from one array (maximum throughput of 1.3 GB/s) to two (almost the same throughput). Each array is connected to a dedicated host bust adapter, so they should not be the bottleneck. The disks are currently in JBOD configuration, so each disk can be addressed directly. I have two questions: Is running multiple DD commands in parallel really a good way to test maximum read throughput? We have noticed very high SWAPIN-% numbers in iotop, which I find hard to explain because the target is /dev/null How shoud we proceed in trying to find the reason for the scaling problem? Do you thing the server itself is the bottleneck here, or could there be some linux parameters that we have overlooked?

• SQL Server Express performance issue

  - by Developer IT

  Hi folks ! I know my questions will sound silly and probably nobody will have perfect answer but since I am in a complete dead-end with the situation it will make me feel better to post it here. So... I have a SQL Server Express database that's 500 Mb. It contains 5 tables and maybe 30 stored procedure. This database is use to store articles and is use for the Developer It web site. Normally the web pages load quickly, let's say 2 ou 3 sec. BUT, sqlserver process uses 100% of the processor for those 2 or 3 sec. I try to find which stored procedure was the problem and I could not find one. It seems like every read into the table dans contains the articles (there are about 155,000 of them and 20 or so gets added every 15 minutes). I added few index but without luck... It is because the table is full text indexed ? Should I have order with the primary key instead of date ? I never had any problems with ordering by dates.... Should I use dynamic SQL ? Should I add the primary key into the url of the articles ? Should I use mutiple indexes for seperate columns or one big index ? I you want more details or code bits, just ask for it. Basicly, every little hint is much apreciated. Thanks.

• Can't upgrade Windows Server 2012 Essentials to Windows Server 2012 R2 Essentials

  - by Magnus

  So today was RTM of Windows Server 2012 R2 Essentials released. I immediately tried to do an in-place upgrade of an existing RTM 2012 Essentials to RTM 2012 R2 Essentials, but get: Windows Server 2012 Essentials cannot be upgraded to Windows Server 2012 R2 Essentials. You can choose to install a new copy of Windows Server 2012 R2 Essentials instead, but this is different from an upgrade, and does not keep your files, settings, and programs. You’ll need to reinstall any programs using the original installation discs or files. To save your files before installing Windows, back them up to an external location such as a CD, DVD, or external hard drive. To install a new copy of Windows Server 2012 R2 Essentials, click the Back button in the upper left-hand corner, and select “Custom (advanced)”. This seems a bit odd, is this really the case? I can't find anything in the official documentation stating that this upgrade isn't possible.

• Windows Server 2012 & Exchange Server 2013 CAL's

  - by Joey Harris

  Trying to build an Exchange server solution for a company and they want me to look into licensing for Windows. I'm going to be purchasing the necessary server licenses for Windows Server 2012 Standard and Microsoft Exchange 2013 Enterprise. I just have a few questions about the CAL's thing which seems like a complete ripoff to me. How are CAL's tracked for both Windows Server and Exchange? Is it tied to Active Directory profiles? What happens if I dont have the necessary CAL's for Windows Server? Will a client be denied access from Active Directory? Is there any enforcement for this? Also the same question for Exchange 2013 CAL's Thanks
