[before anyone corrects me I've used the terms secondary and primary colloquially and I understand the terminology]
I have a problem with my secondary DC, but not on any other server in the domain. Everything is Windows Server 2008. Virtualized using VMWARE. It appears to not be part of the domain anymore. Accounts appear "locked out" on DC2 but are not locked out on DC1. Active directory won't pull up on DC2 and I can't edit accounts to unlock DC2 locally.
Any network pings are "General Failure", including 127.0.0.1 any other server by IP or DNS name. Ping TO the DC2 fail conclusively as well. Everything is fine in the adapter settings and it even shows "connected" to the correct domain, but it can't reach anything else. Services are fine. There are NO enabled firewalls or issues that would arise from connection problems.
I believe it may be a trust issue? I'm not entirely sure
