Paul,
I think you are referring to IC33355, which was closed SUG. I do not know
the details behind the closure, but it was closed that way presumably due
to the complexity (despite the seemingly simple problem description) of
addressing the issue.
I have not been able to reproduce your symptoms. Can you clarify a few
things for me?
1) Content of your two dsm.opt files
2) Output from "dsmcutil list"
3) Output from "dsmcutil query /name:xxxx" for each xxxx that shows up in
the dsmcutil list output
4) Admin console output that illustrates the problem

I have things configured pretty much as you describe, and I also use
dsmcutil to create the services when using a cluster- Way easier to
reduce
mistakes since I can throw it into a batch file and run it on both sides
of
the cluster. :)
The issue I'm seeing, though, can be duplicated on a non-cluster.
(however
the results seem to happen on some systems but not others) If you take a
Windows 2000 or 2003 server and try the following:
1. Install a regular dsmcad, agent and scheduler service using the
default
baclient\dsm.opt file.
2. create a second options file named something different such as
dsm2.opt
3. install a second set of services, named differently, and using the
dsm2.opt, and using a different nodename from the first set. (ie. you
would
use this if setting up a scheduler for an agent perhaps, or for a
cluster
resource group).
4. before starting the dsmcad service, start up a console window
(dsmadmc -console)
5. start dsmcad, wait the minute for the scheduler to kick in
What I see on the console (and in the actlog) is:
- an inital connection using the correct (second) nodename, by the
dsmcad as
soon as I start the service
- 1 minute later, I see two more client connections as the scheduler
connects. the first connection uses the wrong (first) nodename, the
second
connection uses the correct (second) nodename.
other than that, everything seems to work correctly.....
