Help Remote Access driving me bananas

Archived from groups: microsoft.public.windowsxp.work_remotely (More info?)

I've been trying to make two Win XP Pro workstations see each other via
modems, just like Anonymous in "Remote network problem" sent on 9/22/2004.

One has been set to dial and the other to recieve incoming connections and
they do seem to do that.

On the dialing machine View Network Connections reports "Connected "
On the recieving computer View Network connection reports "Connected"
The dialing computer has even been correctly assigned a suitable IP address.

I can't see what to do next, neither machine, nor any shared disk appears in
the other's workgroup or network places, so please, what hugely obvious step
am I missing.
