Hi all, I'm having a problem setting up a SQL 2005 Mirror across 2 servers. I'm using a manual failover at the moment so I don't use a witness server. Server Details: Both have Win Server 2003 + SP1 Both have SQL 2005 running but with different version: - One is 9.0.2047 (SP1) - One is 9.0.3033 (SP2) I've tested both server connecting via port 5022 with telnet and they connect fine, (should do as well as they are on the same gigabit switch!). Using SQL sa user Auth and I keep getting the following when trying to start it: The Server network address "TCP://192.168.1.44:5022" can not be reached or does not exist. Check the network address name as that the ports for the local and remote endpoints are operational. Any ideas? Ta.
