Operations Manager 2007 RTM & W2003 SP2
There seems to be a problem when installing System Center Operations Manager 2007 RTM on a Windows Server 2003 with Service Pack 2 (SP2). When selecting the Management Server role during the setup, the prerequisite checkers alerts about an .NET Interop Assembly problem which was solved by a hotfix reference in Knowledgebase article 915786. When you try to install that hotfix on a W2003 SP2 box, the installers tells you that it was already included in SP2 and therefore does not install. This will actually prevent you from starting the OpsMgr installation.While Microsoft did not post an answer to this incompatibility yet, I managed to find a workaround. When you extract the contents of the hotfix using the /X parameter (eg: WindowsServer2003-KB915786-v3-ENU.exe /x) you will find a file called update_SP1QFE.inf in the Update directory. When you examine this file, you will find that the hotfix will actually run a command after its normal installation. By just running this command on a SP2 box, the OpsMgr prerequisite checker will tell you that all requirements are met and lets you continue the installation:
%windir%\system32\azrlreg.exe register %windir%\Microsoft.NET\AuthMan\1.2\Microsoft.Interop.Security.AzRoles.dll
This command both works on the x86 and x64 platforms. I have asked the Operations Manager product team to comment on this workaround and when a fix or KB article will be available.
UPDATE: It seems that this only happens with a slipstreamed installation of Windows Server 2003 SP2. (Thanks to Clive Eastwood for doing some extensive testing!)









I have this exact same issue and I have ascertained the problem. I hit the MS website when SP2 was first released – downloaded SP2 on 3/8/07, size 387,641,632 bytes. This release of SP2 doesn not contain the AZRLREG.EX_ files – thus none of the established hotfixes will work for me.
The current SP2 download was posted on 3/12/07, is 390,092,144 bytes long, and DOES include the above mentioned file. I used SP2 to slipstream an original Windows 2003 release CD image, which does not already have the AZRLREG.EXE file – but slipstreaming is not the issue here, you need the latest version of the service pack.
