One WIN XP compuer can't connect with RDC

[Tim]

Hi, Hope some one can advise

{RDC = Remote desktop connection.}

I have 3 computers (winxp-pro SP2 all up to date) on my network.

I have selected Allow RDC on all of them.
I have checked that they all have the same services running/ settings (
although they also have different software installed on each unit as well).
They are all connected to the same router.
All have simple file sharing set up and all have passwords required to log
in to each account.
All accounts are administrator level accounts AND I have added the
administrator accounts to the remote users group anyway ( although I believe
that is not needed..)


Now
Unit A can "see" B & C ( Gets an active RDC connection and all goes as
expected)
and B can access C; C can access B as above

BUT neither B or C can access A via RDC

The error message is - "can not connect to the remote computer" ( tried both
name and LAN ip address)

Nothing in the event log of A

There is no problem accessing shard folders b/w any of the computers
including B access A for example. This problem seems exclusive to RDC.

I have tried :-

disabling anti virus AND firewall and windows defender and spybot etc etc
etc on A - then I even uninstalled the Antivirus! No difference

Started A in Safe mode with networking - got a "you were disconnected from
the remote computer" error - before I even saw a connection had been
achieved. Progress I guess but what?

I guess I may have missed something obvious - but what??

PLEASE this is kinda driving me nuts

Short of reinstalling WIN xp - and the massive amount of software
associated..... where too?
