firewalls? port numbers? ancient curses cast upon my servers?

Hello All
I have the client side of my application installed in the US, with the
application and the database servers running in london.
The program language is C#, all built in .net, with the .net installer. When
the user in the US runs the program and it gets to the import progress part
(background processing occurring on London servers), they are getting no
feedback as to the progress of the import. ie, nothing is being sent to the
US from the london server. But everything runs smooth the other way, ie,
tables are written to the sql db's in london etc... And I get data sending
and receiving here in london when i run the client app on my machine and send
to the servers here, so its some problem with the connection with the US...
firewalls' port numbers' ancient curses cast upon my servers' anyone come
across anything like this?
Cheers mikeHave you tested access with Query Analyzer to see if you can connect, access
the database from both places and perform the import tasks? It's unclear
from your post whether you're just having problems with the import task or
if it's even connecting.

Sorry, i will try and clarify:
it is connecting, theres problems with the callback functionality i think, if
that means anything to you.
okay, thanks for your pointers, i'm off to follow them up.
