A few of you posted questions about the WSUS issues that started this morning. If you haven't already found the fix (or maybe you didn't even know there was a problem) check the WSUS Team Blog for information. Additionally, keep an eye on the public WSUS newsgroup for late-breaking info (microsoft.public.windows.server.update_services). As was the case today, you often find people discussing issues in the newsgroup long before something appears on a team blog or on the official Microsoft Support site.
Note: If you aren't into traditional NNTP, just point your web browser to http://www.microsoft.com/communities/newsgroups/list/en-us/default.aspx for the entire list of Microsoft newsgroups (English only). RSS and blogging are great... but a traditional newsgroup is still a fast and efficient way to discuss hot topics.
