The set up of TFS application tier “warm stand by” went well. The steps to set it up are in the section “How to: Configure a Standby Server for the Application Tier in the TFS installation guide” of the [Team Foundation Server 2008 installation guide](http://www.microsoft.com/downloads/details.aspx?FamilyID=FF12844F-398C-4FE9-8B0D-9E84181D9923&displaylang=en). Once we ran the activateAT command to specify the virtual server name we had selected, TFS returned many errors (TF30063; see below for a sample of the event log) ``` Log Name: Application ``` ``` Source: TFS Version Control ``` ``` Date: 5/28/2009 2:30:46 PM ``` ``` Event ID: 3028 ``` ``` Task Category: None ``` ``` Level: Error ``` ``` Keywords: Classic ``` ``` User: N/A ``` ``` Computer: ATMachineName.DomainName.net ``` ``` Description: ``` ``` TF53010: The following error has occurred in a Team Foundation component or extension: ``` ``` Date (UTC): 5/28/2009 6:30:46 PM ``` ``` Machine: ATMachineName ``` ``` Application Domain: /LM/W3SVC/831865381/ROOT/VersionControl-40-128880090463851400 ``` ``` Assembly: Microsoft.TeamFoundation.Common, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a; v2.0.50727 ``` ``` Process Details: ``` ``` Process Name: w3wp ``` ``` Process Id: 3828 ``` ``` Thread Id: 3624 ``` ``` Account name: DomainName\tfsservice ``` ```   ``` ``` Detailed Message: TF53002: Unable to obtain registration data for application VersionControl. ``` ``` Web Request Details ``` ``` Url: http://VirtualATName:8080/VersionControl/v1.0/repository.asmx [method: POST] ``` ``` User Agent: Team Foundation (devenv.exe, 9.0.30729.1) ``` ``` Headers: Content-Length=319&Content-Type=application%2fsoap%2bxml%3b+charset%3dutf-8&Accept-Encoding=gzip%2cgzip%2cgzip&Accept-Language=en-US&Authorization=NTLM+TlRMTVNTUAADAAAAGAAYAH4AAAAYABgAlgAAAA4ADgBIAAAAEgASAFYAAAAWABYAaAAAABAAEACuAAAANYKI4gUBKAoAAAAPRQBaAEUAUwBPAEYAVABKAEsAbwB0AGEAcgBzAGsAaQBLAE8AVABBAFIAQwBBAFMAVABMAEUAvLisuuzUv6kAAAAAAAAAAAAAAAAAAAAAVjEA56O20yN8mf9I854%2bj5Uv5P6dgzJHKyiKXw6Frzq0%2bHPGhl1UwA%3d%3d&Expect=100-continue&Host=VirtualATName%3a8080&User-Agent=Team+Foundation+(devenv.exe%2c+9.0.30729.1)&X-TFS-Version=1.0.0.0&X-TFS-Session=e998d615-a149-43cf-96ca-c9bd3577c1a2 ``` ``` Path: /VersionControl/v1.0/repository.asmx ``` ``` Local Request: False ``` ``` Host Address: 10.3.2.25 ``` ``` User: DomainName\UserName[authentication type: NTLM] ``` ```   ``` ``` Exception Message: TF30063: You are not authorized to access VirtualATName.

We did not have as many issues as he reported but it did point us in the direction of the [Microsoft KB 926642](http://support.microsoft.com/kb/926642). This is the issue with windows server authentication when using fully qualified domain names (FQDN). Since we are attempting to set the computer to use a virtual server name, we believed this could the source of our problem. The KB article does not mention Windows server 2008 but we found a [post](http://social.technet.microsoft.com/Forums/en-US/winserverfiles/thread/94f9b04f-e0a4-41a7-bbf3-b68e9a4c98db) where the workaround was also implemented for 2008. We choose to implement the second method of the KB article:     Click Start, click Run, type regedit, and then click OK.     Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa     Right-click Lsa, point to New, and then click DWORD Value.     Type DisableLoopbackCheck, and then press ENTER.     Right-click DisableLoopbackCheck, and then click Modify.     In the Value data box, type 1, and then click OK.     Exit Registry Editor.     Restart the computer. After the application tier machine had restarted, TFS worked without further issue, the client workstations could connect to TFS by using the new TFS virtual server name.
