We shut down all our servers today as we were going to do some updates to our VMware ESXi Hypervisor host servers but at the last moment we discovered some problems with documentation so we abandoned the upgrades and no changes were made. Upon rebooting all our guest servers (all 2008R2) we noticed that none of our domain controllers (3 of them) were starting properly. All had the same failing services (set to Automatic);
Active Directory Web Services
Diagnostic Policy Service
Microsoft DotNet v4.0.303.19_x64
Microsoft DotNet v4.0.303.19_x86
Windows Event Log
Windows Remote Management
WinHTTP Web Proxy Autodiscovery Service
Not all of those are services that we would necessarily use/need but for thoroughness I thought I would list them all. Now, when we attempt to start some of these services we get the following errors;
DNS Server service
Windows could not start the DNS server service on the local computer. Error 1717: The interface is unknown.
Windows Event Log service
Windows could not start the Windows Event Log service on the local computer. Error 0x800700E Not enough storage is available to complete this operation.
There is about 17gb free on the system drive of the primary DC so I'm not sure what the Event Log error is referring to. We suspect that our problems are related to the Event Log not working but so far any attempts to get it going haven't worked.
Can anyone please assist? Let me know if more information is required...
