I have the client that has a SBS 2K3 DC. For the last few maintanance periods i couldnt install any .net updates - SPs for 2.0 and 3.x, any updates for .net.
update process would freeze (the server doesnt lock up). It also stops my exchange. I left it for 6 hours one day - it didnt complete. I can un-do the update, roll back the changes, and things are working again.
I tried to remove all .net versions, ran clean-up tools from MS. Download .net install files and SPs, re-run installation - all gets stuck at the same point - .net install ok, but cant install any SPs or updates.
so question - anyone experienced anything similar? And what else can i try to fix the problem?
