This is a bizzare problem. Our users and computers that are part of the
domain but are on a different subnet can no longer access shared folders on
one particular server. Group membership and folder permissions have not
changed. The users can access the folders if they log on on the same subnet
as the server. I have made a little bit of progress in the sense that under
network connections, on the workstation, I turned off everything in the
Authentication tab, which I don't understand. Once I did that users on the
subnets could at least browse the network, i.e. see all the workstations and
servers in the domain. They can see all the shares on the servers. However
shares report they are not accessible or they do not have permission, which
they do. Prior to turning the Authentication settings off subnet users only
saw workstations on their own subnet. I have verified their DNS and WINS
server settings.

We had this problem show up last week w/ this same server out of the blue.
I ended up doing an in place upgrade to get things going again. Everything
was fine for the few days we were at work prior to Wilma. This is the first
time subnet users have been able to get back on the network since Wilma came
through. Hence nothing has changed on the server from then until now
becauses nobody was here to change anything. I think this is a security
"feature" of Server 2003 sp1 that I know nothing about. Something that only
affects users when they are on a different subnet. I am at a complete and
total loss as to why and how to go about fixing this. Any ideas would be
greatly appreciated.

Do a network trace and actually look at what is happening. There are so many
different things that could be going on it isn't really logical to just guess.
You can download ethereal for free.
