VAS_ERR_DNS: Unable to look up any DNS SRV records for domain

Hi, I am running AIX5.3 with VAS agent 3.3.1.83. I get an error when running the join command to join the server to AD domain...

It takes a long time to check if the computer is already joined to a domain....and then gives the VAS_ERR_DNS error.

Any one run into this?

Thanks,
