A client of ours has SBS 2008 running on a HP ProReliant ML115. Last week there were some power issues and the server was powered down ungracefully. Since then the server has been giving repeated problems, for example:
Today I went onsite, hard-restarted the system (frozen) and it came up fine (although stuck at "Applying Computer Settings" for about 25 minutes). Client PCs were able to access the internet and network drives. I left and while I was gone, connectivity went down. I cam back and the server was functioning ok but clients had no access.
I restarted the PC, as before stuck at "Applying Computer Settings" for 20 mins or so. It booted up and clients gained access. When it got to "CTRL, ALT DEL" screen, it froze halfway through me entering the password. I left it for 5 minutes and it unfroze and I was able to enter the rest of the password.
I've been completely unable to uninstall the network card (to reinstall it) - all attempts to do this freeze at "Uninstalling".
I've updated the NIC drivers, checked for updates, switched the entire server hardware for an identical ML115 we have on had for this sort of thing, no luck.
I ran a chkdsk offline and it found an repaired some problems, I ran defrag for as long as I could but as SBS gives no indication of progress, after three hours I stopped it.
There seem to be no errors in the event log that coincide with the timing of the freezes.
Does anyone have any thoughts?
