You didn't mention if you are using DNS or flat file /etc/hosts for name
resolution.  I am using /etc/hosts for name resolution and had exactly the same
problem in creating a managed node for a NetView client.  After much
investigation, the solution is to "fake" out Tivoli by copying the
/usr/bin/nslookup command to, say, nslookup.ORIG and then create a fake nslookup
file containing the following commands:

echo "Name: <hostname of TMR server.domain.name>"
echo "Address: <ipaddr of TMR server"

In my particular case, the fake nslookup file contains:

echo "Name:  nvhost.hq.giantofmaryland.com"
echo "Address:  161.247.21.237"

After the install, copy back the original file to the nslookup file.
