Server 2008 R2 Windows Firewall won't start - access denied and other issues
Posted on 2012-09-06
We installed a fresh Server 2008 R2 onto an HP DL380G5 server, ran all waiting updates, all logs were clear, then we delivered to the client and joined to his SBS2011 domain.
Set up as Remote Desktop Server and clients connected and all was working fine for about 1 week.
Then they called because Acrobat would not start, just closed straight away like a DEP problem.
We switched DEP to just windows files and rebooted, no longer could we contact the server, so we went onsite and it was at the login screen, it could see outbound to the internet, but nothing on internal LAN could ping or she shares on this server anymore.
We found that the windows firewall service would not start due to Access denied, error 5.
We bought the server back to our office and have tried everything that we can find but have run out of ideas.
I have checked the GPO's at the site, but this server was only getting the default domain policy and that has no settings that might cause this mess, that I can see.
The server has been disjoined from the domain and still has this issue, I am about to rebuild it but don't want to until I can understand what happened here as to avoid it happening again.
