Hi everyone, I have asked this before and asking again. Current setup - 3 Server all DC and running windows 2000 Enterprise server. The first server that was installed with windows 2000 Ent. And Exchange 2000 Ent. With AD, DNS and IIS (do not ask me why because was already setup before I joined the company). On this server I have copied the inetorgpersonprevent.ldf and try to run it I am getting following error. I have setup the schema update in mmc also for the server also. But when I run the intetorgpersonprevent.ldf, I receive following. Any one has any Idea.?????

An error has occurred in the program As per other suggestion, I went to other DC and try on that server and I receive following error Connecting to "acctsrv.amtsolution.com" Logging in as current user using SSPI Importing directory from file "inetorgpersonprevent.ldf" Loading entries 1: CN=ms-Exch-Assistant-Name,CN=Schema,CN=Configuration,dc=amtsolution,dc=c om Entry DN: CN=ms-Exch-Assistant-Name,CN=Schema,CN=Configuration,dc=amtsolution,dc=c om change: modify Attribute 0) LDAPDisplayName:msExchAssistantName Add error on line 1: Referral The server side error is "A referral was returned from the server." 0 entries modified successfully.
