Hi Rob, Have you removed connection agreements and Active Directory Connector from your AD? If you dont delete CA and ADC after removing Last Exchange 5.5, it shows the error you have mentioned. Regards..Anil -----Original Message----- From: Rob Freeman [mailto:sysadmin@xxxxxxxxxxxx] Sent: Wednesday, May 21, 2003 5:56 PM To: [ExchangeList] Subject: [exchangelist] SchCache http://www.MSExchange.org/ After removing the final exchange 5.5 server, we are still having our 2000 exchange server look for it. I see in the event logs and this is what I get: An RPC communications error occurred. Unable to bind over RPC. Locality Table (LTAB) index: 145, Windows 2000/MTA error code: 1722. Comms error 1722, Bind error 0, Remote Server Name TPSC-MAILSERVER [MAIN BASE 1 500 %10] (14) I have looked everywhere on the machine, but can not find why it is still attempting to contact it. The only mention of the old server is in the registry as: cn=Aggregate,cn=Schema,cn=Configuration,ou=TPSC,o=TransPlatinum %SystemRoot%\SchCache\tpsc-mailserver:389.sch Do I need to purge or refresh the SchCache to get rid my exchange 2000 server contacting a dead server?
