I have an Exchange 2010 SP1 that I tried to update to SP2. The install failed on Step 8 - Languages.
Now I am getting an error when trying to connect to owa inside or out side. It's an asp.net error in event logs
Error
Perormance counter names and help test failed to unload. Unloadctr exited
with error code '1224'.

I am then brought to this site - http://technet.microsoft.com/en-US/library/ms.exch.err.default(EXCHG.141).aspx?v=14.2.247.1&e=ms.exch.err.Ex6B3129&l=0&cl=cp
which tells me
You've found an error that doesn't have an article written about it. Don't worry though, help is still available. The forums are the best place to start.
