System.TimeoutException: the operation has timed out -
原因
Anti-Virus software (AV). Specifically h
AV exclusions not added into tool to allow process to work, this windows event log error usually means. (The Error processing 'ReadPasswordChanges' activity). Related to the sourceAll errors are password sync errorsThe Dirsync agent contacts the Domain Controller for jobs related to recent password change, retrieves the hash file, processes, sends it over to target using pcex. Anti-virus picks it up and flags it. Need to add it to exclusion list / whitelist it. -
対策
Add Anti-Virus exclusions. There is a different installation path for agent server versus the domain controllers1. For the target domain controller, the BTPass folder must be added to AV exclusions list.
Exclude this folder: c:\windows\BTPassAlso add exclusions for all three modules (programs) in the BTPass Folder:
For Windows Defender Antivirus
Include the following on the target DC
