what Ports are used to map a remote drive

[Tom Celica]

We want to map a remote drive in our production network from our corporate
network. The Network Admin asked me what ports do I need to be opened
between the two sites. The drive at the remote site is a Windows 2000
Server NTFS formated drive on a stand alone server. The Client is also a
windows machine either XP or Win2k or Win2003. I'm pretty sure that some
authentication will occur when the remote drive is mapped. We will probably
execute a commande like this: net use r: \\remote.machine.com\c$ password
/user:[email protected]

What ports on our firewall need to be opened so we can map a remote windows
drive ?

thanks

Don't do it! Not that way. You need to set up a VPN. I suppose a firewall
that only allows the specific ports to be opened from a specific IP address
would be a bit safer, but you can set up a VPN by opening port 1723. Any
Windows 2000pro or XPpro or 2K/2K3 server can accept a VPN.

Security is most important. We do IP Qualify incoming traffic; only traffic
arriving in production from a specific IP can access exposed resources.
What we wanted to do; was again IP qualify incoming traffic, and port
forward to our specific server and allow a specific machine in corporate to
have mapped drive to a specific server in production. We don't know what
ports are needed to allow the internal corporate machine to map that
production machine.

A VPN would exceed the current needs, and Remote Desktop exceeds the current
needs also. We don't want this internal corporate user to have full access
to the subnet which the production server resides in.

You could use web sharing, or here's a link to the MS page of required ports
for Windows services.
