SQL Server Configuration Manager unable to connect error - fixed!
I had to re-install Windows on my laptop today due to some disk errors. Once I was back up and running, I found that 99% of SQL 2005 worked fine, but SQL Server Configuration Manager had stopped working and gave the following error in a dialog box:
Cannot connect to WMI provider. You do not have permission or the server is unreachable. Note that you can only manage SQL Server 2005 servers with SQL Server Configuration Manager.
Invalid class [0x80041010]
Unfortunately that error does not tell you what to fix. Fortunately Eric Charran does tell you what to fix. You can find the answer on his blog here: http://blogs.msdn.com/echarran/archive/2006/01/03/509061.aspx. I had not dealt with .mof files before now, but his fix did the trick in about 2 seconds. Thanks Eric!
