During Synchronization the following errors are received: "Cannot contact the LDAP server" -
说明
During synchronization you may receive the following errors: "Failed to retrieve information about the following domains: [Domain's DN] (Cannot contact the LDAP server.)" and "Collection <[Collection Name]>: Failed to process collection. Code : 0x80040473,Description : Unknown domain."
Also QCS service may fail to start with an error similar to the following: Faulting application ACSSyncService.exe, version 3.7.0.142, faulting module ACSADManager.dll, version 3.7.0.142, fault address 0x00027bd1.
-
原因
These errors are caused by the synchronization service being restarted while a Domain Controller was not available - "Cannot contact the LDAP server". As a result, the synchronization will continue to fail with the "unknown domain" errors.
-
解决办法
Ensure that the all domains in the forest are accessible and Domain Controller connectivity is resolved, and re-start the synchronization service (Quest Collaboration Services Synchronization Service).
