In site addressing, when try to open (Routing Tab) recieve error, “DS_E_DIT_ERROR”. Knowledge Consistency Checker get’s Event ID 1124. MTA event ID’s 2253, 2256, 2257, 9330. Have checked MS Knowledge base and Exchange resource, some of these ID’s are not listed. Everything appears to be correct in registry. Stopped and Restarted Services Several Times. Remote and Local Bridge Head Servers IP’s are in lmhosts and hosts files. GWARTS are not correct. Any ideas???
