Have a single 2003 SBS server in an office. All patches have been installed. Every few days Exchange fails. Each time a reboot of the server fixes the issue.
When it happened this morning I checked the Event Viewer and the following Errors showed (in order of appearence)
Error ID 8026 MSEchangeAL Process STORE.EXE (PID=4340). All the DS Servers in domain are not responding
Error ID 8026 MSEchangeAL LDAP Bind was unsuccessful on directory 2k3server.fa.local for distinguished name ".Directory returned error:[0x34] Unavailable.
Error ID 2104 MSExchangeDSAccess Process STORE.EXE (PID=4340), All the DS Servers in domain are not responding.
Error ID 2102 Process MAD.EXE (PID=3468) All Domain Controller Servers in use are not responding: 2k3server.fa.local
This error last occurred 7 days ago and the log then had hundreds of the same errors as above.
Would really appreciate any thoughts on what might be going on here. I'm not generally a tinkerer when it comes to this server so other than installing regular updates I don't touch the thing enough to break it!
