If you can see the WSUS server: <NULL> and WSUS status server: <NULL> I don't know how to solve this...

After checking the issue, it seems this is a general WSUS issue. As this forum focuses on Windows Vista specific issues, this inquiry would best be posted to WSUS newsgroup: http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?dg=microsoft.public.windows.server.update_services The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the newsgroups regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
