Password Export Server 3.2 – Unable to establish a session with the password export server

While doing cross forest move between Exchange2010 to Exchange 2010 , I had to configure PES (Password Export Service) to migrate passwords of the mailboxes


If you are confused with the first line,Please read the below post and come back.



Below error was popping up :

“Unable to establish a session with the password export server. Either the currently logged on user does not have sufficient permissions to call the Password Export Server or the account that the Password Export Server Service is running under does not have sufficient permissions on the target domain controller. Verify that the logged on user is a member of the Administrators group in the source domain and that the Password Export Server Service account can change passwords of user accounts in the target domain.”



My fix :

Created a Service Account

Name: ADMT

Member of (TargetDomain – DomainAdmins)

Member of (SourceDomain –Administrators)

And Configured the Password Export Server Service Properties



Waited for few minutes.

Logged into domainController of the TargetDomain  Using the Service Account.


Now it allowed me to migrate passwords
