Client has been running fine for years, no problems other than the occasional iisreset to get EMC to load properly.
The past week we started seeing strange errors and now today it's a complete outage of Exchange service for us.
OWA loads with
The Microsoft Exchange Active Directory Topology service on server localhost did not return any suitable domain controllers.
That error shows about 20% of the time, other than that, it's always
Active Directory server is not available. Error message: Active directory response: The LDAP server returned an unknown error.
Domain Controller is a Windows Server 2003 machine that was physical and migrated into a VM at some point, but has not had any issues since then.
We inherited this setup in about April, no changes have even been made in that time.
Not entirely sure on where to go from here, I can bring up...
