My server wasn't using DHCP so I removed the role and rebooted. When it came back on I can no longer update my role list on the server manager snap-in. This is the error that I get. What could have caused this and how do I repair it?

Hi, What OS are you running? If it is 2008 or later, can you run the SUR tool and post the log output at %systemroot%\logs\CBS\CheckSUR.log, http://support.microsoft.com/kb/947821 -- Mike Burr

I ran that yesterday to get it to quit hanging on Stopping Services from powering off. Here's what the log says ================================= Checking System Update Readiness. Binary Version 6.0.6002.22441 Package Version 9.0 2010-11-12 16:20 Checking Windows Servicing Packages Checking Package Manifests and Catalogs Checking Package Watchlist Checking Component Watchlist Checking Packages Checking Component Store Summary: Seconds executed: 1535 No errors detected

In this case, can you upload the CBS.log file from c:\Windows\Logs\CBS\CBS.log to skydrive, http://mikemstech.blogspot.com/2010/08/skydrive-uploading-files-for-community.html-- Mike Burr

Here you go hopefully you can make some sense of it http://cid-df8c3b6065733c2c.skydrive.live.com/redir.aspx?resid=DF8C3B6065733C2C!105
