Re: MSDTC doesn't work on SQL 2k in W2k3 cluster environment

You are correct in that you should have followed the correct and documented
installation sequence; however, you should be able to do it after the fact.
Also know that there is a COM 1.5 bug in Windows 2003.

First, after reclustering the MSDTC, did you configure it within its own
dedicated Cluster Resource Group? It will require the creation of this
group, a dedicated SAN disk, IP, and Network Name cluster resources. Then,
you will need to fail that resource back and forth between the nodes to get
the resource registry entries to synchronize.

You will then need to take the SQL Server IP resource offline, which should
bring the resources in that group offline and then bring the group back
online.

In the SQL Server Error Log, you will see SQL Server attempting to connect
to the DTC resource; if it opens the connection, there will be no additional
messages. If it has a problem however, it will spit out a "Could not
generate resource context" type of error message. That will tell you if
this worked or not.

If this process fails, one other option would be to run through the ADVANCED
section of the SQL Server installation processes. This should
verify/generate the necessary registry key dependencies without having to
completely reinstall.

If this too does not solve the problem, then before you uninstall/reinstall,
I would seriously consider opening a Microsoft Product Support Services
case, MS PSS.
