Ken,
Thank you for your suggestions. I downloaded the CATDUMP utility, but before I had a chance to use it, the network browse list issue was resolved.
Just FYI: Our server comment field on the computers missing from the Network browse was greater than 48 characters. I know it sounds odd, but there is a MS tech article, (# 231312), addressing this issue. We edited the "missing" PC server comment fields and they are now appearing in the network browse.
Thanks again,
Beverly
