Have you checked that all SAS services on both app servers are up and running? You could also try rebooting all of your SAS servers in the correct sequence.

Also raise a track with SAS Tech Support as they can get you going faster.

Lots of things could cause this problem.

1. DNS changes such that the dpds1335a cannot resolve dpds1336a
2. Firewall changes on dpds1335a that prevents dpds1336a from connecting
3. Network equipment breakdown.
4. LIM is hung on dpds1335a
5. License has expired.

So you can do the following:

• Make sure LIM is running and responding on dpds1335a. Run 'lsid' on dpds1335a
• Make sure you can ping dpds1335a from dpds1336a.
• You could also try to telnet from dpds1336a to dpds1335a on the LIM port.
