Hi Mac, Please let me know how many DCs exist in the environment. If several DC exists, please check whether any replication issue exists. Regarding you cannot locate the second Exchange Server in AD, would you please let me know: 1. You cannot locate the second Exchange server in Computers by using ADUC tool 2. Or you cannot locate the second Exchange server in Administrative Group by using Adsiedit tool Configuration->Services->Microsoft Exchange->Org name->Administrative Groups->AG name->Servers Please also let me know whether the two Exchange Servers are in the same Domain. Mike

I have 2 DC's both on W2K3 servers & replication between them seems fine. I am not familier with those two tools, sorry, but I will look for them. On both Exchange servers I only see the first Exchange server when I open Exchange System Manager. Thanks.
