Hi,
I have an interesting issue I'm trying to solve. Hopefully I'm missing something really simple. Here's a description of our environment, and the issue I'm having.
2 node SQL 2008 R2 SP2 clustered named instance. There are a total of 4 instance names on the cluster.
Node 1 IP is 192.168.1.121
Node 2 IP is 192.168.1.122
Named instance IPs are 192.168.1.123 to 192.168.1.126
Now here's my dilemma. When I connect to a linked server from one of the 4 named instances, instead of the remote server seeing the named instance IP (eg, 192.168.1.126), it's seeing the IP of the node that is hosting that instance (eg, 192.168.1.121). This is causing us an issue, as the remote SQL server is behind a firewall, and we expected it to use the instance IP and not the host IP. I have already tried to force the IP in the Server Configuration Manager for the instance name, but this has not helped.
The server logs for the instance show it listening only on the instance IP (eg. 192.168.1.126 <ipv4> 1433).
All communications to the named instances use the correct IP, and not the node IP. Any help would be greatly appreciated.
Regards,
Hugh McDaid
