I am running a Windows Server 2008 Standard x64 server as a domain controller (not primary DC). For the past three weeks every time I try to use the Roles or Features functions to manage the services installed on the server I get the following error logged in the Event Viewer:Log Name: Microsoft-Windows-ServerManager/OperationalSource: Microsoft-Windows-ServerManagerDate: 6/8/2009 3:59:30 PMEvent ID: 1601Task Category: NoneLevel: ErrorKeywords: User: {text removed}Computer: {text removed}Description:Could not discover the state of the system.

I tried installing Service Pack 2, however it failed and prompted me to run the System Update Readiness Tool for more information. When I ran that tool it reported that it couldn't install because some of the mum files required for the update KB961063 (which I can't install) are missing. Again, I do not know if these update errors are related to my original problem.

hi there, since when you are encountering error ?please check c:\windows\logs\cbs\cbs.log file this file will log error messages and do let us know.difficult to say if the issue is related to any updates as of now.sainath windows driver development.

Hi Mike, I think the root cause is the missing of the mum files. The following post discuss the similar issue to yours, you can refer to: http://social.technet.microsoft.com/Forums/en-US/winservermanager/thread/4d75e98e-ed8f-40f0-a88b-931ab853e1b8 Best regards, Vincent Hu

THank you for your suggestion. I suspected that the missing mum files might be the problem. As a result I downloaded the individual updates andextractedthe missing mum files. I was able to find all of the files I need except for one. Here is what the System Readniess tool now reports:=================================Checking System Update Readiness.Binary Version 6.0.6001.22375Package Version 5.02009-06-24 20:51 Checking Deployment Packages Checking Package Manifests and catalogs.

The file names I have are:"package_1_for_kb961063~31bf3856ad364e35~amd64~~6.0.1.0.mum""package_2_for_kb961063~31bf3856ad364e35~amd64~~6.0.1.0.mum"Is there a way I can tell it to use these two files instead of the missing one that it is looking for? Or is there somewhere I can obtain the single file that it is looking for? I unfortunately do not have another 64-bit 2008 server available to me at this time to copy files from.

UPDATE - I copied the mum files that I was able to download from Microsoft for KB961063 into the packages directory and I was able to get that update to install properly. (It must have figured out on its own that the single file it was looking for was actually two files.)However, I still cannot get update KB951847 to install. (This is the .Net framework 3.5 Service Pack 1 update.) I also still am unable to use either the "Roles" or "Features" functions.I tried downloading KB951847 from the Microsoft Update Catalog, however this gave me an error message saying that I needed to run "setup.exe" in order to install the software. The only problem is that no setup.exe was included in the download.I then tried downloading the .Net Framework 3.5 Service Pack 1 installer from downloads.microsoft.com. When I tried to install this I recieved a log with the following error messages:[06/24/09,21:56:46] Optional Component 'Microsoft .Net Framework 3.0 (x64)': [2] Error code 1168 for this component means "Element not found."[06/24/09,21:56:46] Optional Component 'Microsoft .Net Framework 3.0 (x64)': [2] Component Optional Component 'Microsoft .Net Framework 3.0 (x64)' returned an unexpected value.[06/24/09,21:56:46] Optional Component 'Microsoft .Net Framework 3.0 (x64)': [2] Return from system messaging: Element not found.

[06/24/09,22:17:16] WapUI: [2] DepCheck indicates Optional Component 'Microsoft .Net Framework 3.0 (x64)' is not installed.It appears that it is complaining that .Net 3.5 is dependent on having .Net 3.0 installed first. So then I went back to downloads.microsoft.com and downloaded the installer for .Net Framework 3.0. Upon trying to use this installer, I recived the following message:You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.0.This is a problem because I am unable to use the Role Management Tool. How can I resolve this situation?Also, I ran the System Update Readiness Tool again and it does not report any problems with the instalation of KB951847.

hi mike, Did you had a chance to work on the issue ? if so please do let us know how you resolved the issue ? if not please let us know so that we will resume troubleshooting.sainath !analyze

Thank you for following up on this. I did get the problem resolved under a different post: http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/12619e65-8c09-418e-beab-3365318c9002
