we are trying to talk over a 2mb link using intel routers - sending from A to B is o.k however sending from B to A crashes - hangs momentarily- the pc then an error consistent with not seeing the other end is displayed - extensive checks have been carried out on the line between A and B - no errors found.
A packet analyser shows an SMB too short erro on the A end - the routers were swapped from A to B but the problem remains the same - it did not swap round - any suggestions welcome.

Use the analyzer to check the packets between the PC and the router on the A end. It may be a problem with the PC rather than the router.

Good luck.

fault resolved - it turned out to be the clocking signal too week on the A end end of the megastream.

I had a situation where I could send data one way but not back. I also switched ends and still could only send data one way-- the same. It turned out to be a repeater on our T1 in Sprint territory. I am curious are you checking serial stats?

probable cause may be Access List in your Router B, which may not be allowing packets to come in from A's IP Addresses. Have you tried sending packets from other locations or changing the source IP sending packets to Location B ?
