From: E-Double on
In an attempt to setup a virtual folder to a directory that resides on a
remote, second domain (no trust established) the IIS virtual folder is being
configured to point to the remote folder (on a seperate domain) and the
credentials are in the following format: domainname\username, password. We
are able to access the remote folder using this method from My Network Places
(so the IIS server machine sees the remote machine and folder) but for some
reason this will not connect from within IIS. Is there some additional
configuration step(s) that must be performed in order to get this to work -
and without setting-up a one-way or two-way trust ? On the local domain
setting-up a virtual folder is pretty straightforward, but for some reason we
are having issues connecting to the folder on a second domain (no trust).

TIA ...
