Event ID 2121, 2104, 1121 and 5000
Starting at 6:12 this morning my Exchange server 2007 lost connectivity to the domain controller for an unknown reason. I don't know what happened to cause this as no reboot was performed, power outage or updates, it just seems to have happened. I have since tried to reboot the server and also manually restart the 3 services that fail to start (Information Store, System Attendant, Service Host) but neither worked. I have verified connectivity to the AD/DNS server with ping and nslookup and both report fine. From the exchange server I am able to browse the network just fine and see all of the other servers and workstations. I have other apps on other servers that also depend on AD and they are working just fine.
