[ADSM-L] TSM client schedules fail because of reverse resolves

Greetings,
        We are seeing some unusual client schedule behaviors that seem
to be related to the fact that our company is combining multiple DNS
domains into one big new domain.  Sometimes a client will be moved to
the new domain, but the DNS entry may show it still reverse resolving to
the old domain.  The client schedule then fails with:

05/03/08 18:30:10     ANR2716E Schedule prompter was not able to contact
client 
                       SPRG-VNACERT using type 1 (sprg-vnacert.smrcy.com
1823). 
                       (SESSION: 1122)

05/03/08 18:30:41     ANR8212W Unable to resolve address for
sprg-vnacert.smrcy-
                       .com. (SESSION: 1122)


        I don't see why TSM has such a big problem with this.  When the
TSM client first connects to the server, the TSM caches the IP address.
You can see the IP address with 'q node xxxxxx f=d'.  I always thought
the reason for this was that when it came time to reach that client to
run its schedule, it would do it using the IP address.  But now I
understand that it tries to do a reverse resolve on the IP address.  In
this case, a reverse resolve on the cached IP address yields:

sprg-tsm1_root# nslookup 10.126.33.164
Server:  stl-pdcp001.smrcy.com
Address:  10.2.215.158

Name:    sprg-vnacert.sprg.mercy.net
Address:  10.126.33.164

sprg-tsm1_root# 

Note that the domain name is different.  But if I try to forward lookup
the name it works correctly:

sprg-tsm1_root# nslookup sprg-vnacert.smrcy.com
Server:  stl-pdcp001.smrcy.com
Address:  10.2.215.158

Name:    sprg-vnacert.smrcy.com
Address:  10.126.33.164

sprg-tsm1_root#

So what if the reverse look up doesn't work?  TSM has the IP address,
and that is what it needs to reach the client, isn't it?
