In the past I have successfully performed domain joins/disjoins over a PPTP
VPN connection for WinXP. I have been unsuccessful in joining a Vista
Ultimate machine to the same domain. I receive an error informing me that
the format of the domain name I am using is incorrect (the domain name is an
unregistered private one of the form: companyname.llc, reflecting the LLC
status of my company). I don't know if this is the source of the problem or
not, but I also cannot reach network shares either.

Even though I can establish the VPN connection from the Vista machine and
establish RDP connections to remote hosts, I cannot access network resources
via UNC paths - the error indicates the network path cannot be found - could
this underlying problem also be the reason I cannot join the machine to the
domain?

Is there some inherent security in the Vista OS that I need to configure to
permit the resolution of UNC paths and join the machine to the domain?

Thanks for any solutions you may offer.
