No SQL connection after OCS F-E's IP was changed RRS feed

  • Question

  • We deployed OCS 2007 R2 Enterprise on Wi Server 2008 and installed B-E to a SQL 2005 cluster (on Win Server 2003) on NON-Default Instance, in NON-Default port.
    We made SQL Alias to point different SQl Instance and TCP-port with Connectivity Components on OCS F-E.

    Everything was fine and working. Then, for a reason, we needed to change VLAN and IP. On new VLAN, exactly same ports are open between servers.
    After this change, non of OCS Services starts. RtcSrv (OCS F-E Service) is on Starting state and Server is slow on any users action.

    We have changed DNS-records and cleared caches on every DNS Server and OCS/SQL Servers.
    When Tracing network traffic, it seems that SQL Browser (Process?) is trying to connect SQL server and it scans UDP(!!) ports from 1->... time-out comes after few minutes and RtcSrv fails to start.

    We have made SQL alias again, only thing changed is that OCS F-E tries to connect to the right IP now.

    Thank You for Your help!!

  • Has the SQL Cluster's registration in the DNS checked ? I would think that it is the DNS registration of the cluster was wrong.
