Need help connecting to a server that is in another domain/subnet

Situation: I have a number of clients who are on different subnets/domains
who need a resource in my subnet/domain. (Ex: The server is in the 128.82.174
subnet; the users are in the 128.82.224 subnet, and they authenticate to a
different domain.) These users all have login accounts prepared on my server.
What I want to do for these clients is map them a drive letter to a network
share on my server, but I'm having difficulty setting up the connection.

I've tried to set up the server as a trusted site via Internet Explorer, but
when I go to map the drive, I get an error that says the path cannot be
found. The users are able to ping the server. User are all running XP SP2,
and I'm trying to connect them to Windows Server 2003 SP1 box. Suggestions?

One other thing: There are no firewall issues that either I or the sys admin
at the other end can detect.

Hi - see my reply in m.p.windowsxp.security_admin. In the future, please
don't multipost - if you need to post to multiple groups, it's best to
crosspost instead, by posting a single message to a handful of relevant
groups (separate the NG names with commas) so that everyone can follow the
thread. Multiposting wastes everyone's time, including yours, and may lead
to your actually getting *less* help rather than more.
