If using a domain account to install SQL server 2008 R2 for SCCM, you have to register a SPN (Service Principal Name) in Active Directory for that domain account. Two SPNs for the account should be registered,     1. For NETBIOS name of the SQL Server     2. For the FQDN of SQL server. The procedure to do that is as follows 1. Log on to a domain controller; open a command prompt with administrative privileges. 2. Type the below commands replacing SQL server name. setspn –A MSSQLSvc/< SQL Server NETBIOS name >:1433<Domain\Account> setspn –A MSSQLSvc/< SQL Server FQDN >:1433 <Domain\Account> 3. As shown in the below screenshot, the server name here is  CM2012 for NETBIOS name and CM2012.CONTOSO.COM 4.  Verify the registration of SPN by typing the below command Setspn –L  <domain\account>

On Windows 7 SP1, after having installed the lastest version of the Windows Update Agent, 7.6.7600.256, from the online Microsoft Update site, I can no longer use the recommended way on MSDN to determine the current version.

When I do:

[version](New-Object -ComObject Microsoft.Update.AgentInfo).            
GetInfo('ProductVersionString')            

I get the following:

wrong WUA version

Why?Because the COM object and

IWindowsUpdateAgentInfo::GetInfo method retrieve the current file version of Wuapi.dll

Solution? Query the WUA engine file.

[version]((Get-Item C:\Windows\system32\wuaueng.dll).            
VersionInfo.FileVersion -split "\s")[0]

WUA correct version

Weird, isn’t it? According to the KB949104, about How to get the latest version of the Windows Update Agent? I’m supposed to have a wuapi.dll version 7.6.7600.256 in C:\windows\system32.

Unfortunately, there isn’t any standalone package of the WUA version 7.6.7600.256 provided by Microsoft for the moment.

I may have figured out why 🙂
The file wuapi.dll is contained in the WUA component named ‘Aux’, whereas the wuaueng.dll is located in the WUA component named ‘Core’.

Get-ChildItem c:\wuapi.dll -Force -Recurse -ea 0 |             
    ForEach-Object -Process {            
        $_.FullName ;            
        $_.VersionInfo.FileVersion            
        '-'*119            
    }            

recurse wuapi.dll version

When I use the dism /online /Get-Packages command, I can see that the ‘Aux’ WUA selfupdate package has been ‘Staged’ (for the moment?).

I know the Windows Update Agent is installed by Windows Updates automatically. But how can I check where it is installed? What is its version?

Thanks!
