Like I said, browse list problems can be a real PIA. Run the command net
config server on both of them to make sure they are not reported as being
hidden. I would also run the support tool netdiag on both of the dc's to see
if anything unusual is reported. Note that it is not unusual for netdiag to
complain that workstation service is not bound to any adapter for whatever
reason but I always still like to use it. I am keeping my fingers crossed
that this will sort itself out with time as I am about out of ideas also. Oh
one more thing I just though of, open Local Security Policy on the two
domain controllers and make sure that the security option for "additional
restrictions for anonymous access" is NOT set to "no access without explicit
anonymous permissions". Look under security settings/local polices/security
options. See the KB link below for more info on how this setting can cause
browse problems and the associated registry key that you may want to
check.--- Steve
http://support.microsoft.com/?kbid=246261 -- make sure this setting is NOT
enabled.
