We have an SBS2008 box that has been built for around two years and has been performing well - no issues, clean event logs etc.
We went through our usual monthly MS patching routine and rebooted the server only to find that when it rebooted, some services failed to start, including DNS, Event Log Service and NetBios Helper. Also, if you try to log in right after the Ctrl-Alt-Del prompt comes up, you get an error saying that you can't log in as the Netlogon process isn't available. Wait a little longer, and you can log in. Safe Mode returns the same results.
The only way that we can restart the server normally, is to change the default system locale from UK to US, reboot the server (comes up as it should), change the default system locale back to UK, reboot the server, and it comes up as it should. This is clearly not a good situation.
Server has Exchange 2007, Symantec BESR 10, AVG 2011 Business Edition, APC Powerchute installed. The internal Sharepoint site is up and running. It has one NIC. We have a second LoB server (Windows 2008) that is a member of the domain. Nothing too complicated.
We use Symantec BESR for backups and have put the image onto another machine which displays the same problems. On this machine we have tried the following:
Event Log only has one error relating to DCOM not being able to communicate with another server, but that is a firewall issue on the other server
dcdiag - returns no issues
sfc /scannow - no integrity violations
SBS2008 BPA - nothing found
MS IT EHS - only found one issue under File Replaication Service and SYSVOL Admin (The file could not be written on the server01.mydomian.local server - See KB249256 but this is not relevant to our environment
Checked the C:\windows\winsxs\ folder for pending.xml - nothing found
One other thing that we think may cause the issue is the version of APC Powerchute that we have seems to cause a lot of problems. It won't uninstall through Control Panel and we have posted to their forums to ask for manual uninstall instrucions.
Does anyone have any solutions that may help in getting our server to boot normally, and also does anyone know how our strange workaround (found through Googling) gets us round the issue of services not starting?
