    I have installed SQL activepassive cluster on a windows 2003 server, however I cant get SQL to failover to the secondary node, its tries and then times out and fails back to the primary node. I have a a lot of ODBC SQL driver connect erros in the application log. Has anybody encountered this ?

    Hi Argyle,

    I have documented the information that you have requested. The cluster works except that SQL won't failover to the secondary node when I fail the resources or reboot the primary node.
    I have been told that this may be because windows 2003 is a fully locked down server and hence I may have to enable specific TCPIP UDP ports that are used by SQL, I edited the registry and added the following ports to the ListenOn key under MSSQLServer (ports 1435, 1436 & 1437. I followed the documented Microsoft process (Article 815431) when installing SQL and have also insatlled SP3a. SQL is installed on both nodes, however on the secondary the SQL manager doesn't have any servers or services listed. All istalls have been done using an domain admin account which is a member of the local admin group.

    Requested Information

    Application Log:
    EventId: 17052
    Source: MSSQL$WSDB000xxxx
    Description: [sqsrvres] ODBC sqldriverconnect failed

    Note: This error keep repeating until SQL fails back to the primary node

    System Log:
    nothing in regards to SQL

    I went through the log and couldn't see any errors in regards to SQL

    Probably what was happening was that it was takeing so long for the DNS lookup to fail that the SQL Server ODBC connection attempt timed out.

    I would verify that your first node can resolve names correctly i.e. ping the SQL Virtual Server by name.
