I'm making a migration of domain and mail servers. I create a new w2003 domain and install two exchnge 2007 servers. I migrate accounts using ADMT. I try to move mailboxes form exchange 2000 to exchange 2007. The scenario is:Origin Domain: Windows 2000 domain with one W2003 DC added Origin Server: Exchange 2000Destination domain: Windows 2003 domain (all dc 64 bits)Destination server: Exchange 2007.when I run move-mailbox : $co = get-credential Move-Mailbox -TargetDatabase "First Storage Group\Mailbox Database" -Identity origindomain\account1 -SourceForestGlobalCatalog dc2.origindomain.local -DomainController DC01.destinationdomain.local -NTAccountOU "CN=Users,DC=destinationdomain,DC=local" -SourceForestCredential $co I recibe the error: Active Directory operation failed on dc2.origindomain.local. This error is not retriable. The operation was aborted because the client side timeout limit was exceeded. At line:1 char:1 ...dc2.origindomain.local is the domain controler with windows 2003 added to met requeriment for move-mailbox Any ideas?Thaks in advance
