no, open registration and the default nodename are unrelated.

Rick,

If your hostnames are unique in of themselves, you can leave the
nodename out of the dsm.opt file. TSM will use the hostname for the
tsm
nodename.

If you have clients with the name of xyz.abc.com and xyz.qxr.com then
you would have a problem with this scheme.

This is a strange problem.

Once in a while, our Windows support team will clone a Windows server.
The
clone will have the exact same TSM setup as the source server.  I'm
not
familiar with the Win BA client, but it seems it always has a nodename
line
for the dsm.sys file, so the clone reports to TSM server that it's the
same
node as the clone source.  They both appear to respond to the same
schedule.   This results in the new server performing good backups to
the
exact same node as the server that is the clone source.   The end
result
seems to be to two different servers happily  backing up the same TSM
node.
Obviously what we get is a useless mess.  When they clone a system
they
are
supposed to use a source without a TSM setup, or,  clean out the TSM
setup
right away, but sometimes this doesn't happen.  I've tried to find a
way
to
detect this from the TSM server, but I'm not coming up with anything
obvious.   I'm interested if anyone else has fought this problem and
what
you've done.

Thanks!

Rick
