Sticky Ip Address

We moved one of our NMS servers that runs Orion to a new network and gave it a new IP address, removed the old devices, discovered the new network and added the new devices as normal. The problem is the SolarWinds Information Service svc2 keeps trying to poll the old server address. How do I stop this from happening. I cannot find that address anywhere in the server. I created an ACL in my switch to block it but it creates a new log entry every 5 seconds.
