IPod Touch doesn't get recognize

Question

Ok, here's the deal, have the iPod 32gig 2gen, nice of course.
Connects with my home tower computer, no problem
It has stopped connecting with my work notebook, IBM T43 computer
it gives the error that an iPhone is not recognized and to disconnect
and try again, to no avail...
BUT
IF
I disconnect from the internet, start up iTunes
AND then connect the Touch, voila, all is right with the world
AND then I reconnect to the internet and everything still works and syncs
I can also verfiy that version 3.0 is the most uptodate version as well
as getting onto iTunes store if I like.
BUT
if I disconnect the Touch and try to reconnect, I get the same warning
and it won't hookup, I HAVE to go away from any internet connection in order
for me to work/sync to my Touch.
BUT at least now I've got that work around and can continue my life
It must be something in this particular computer, firewall or something that
is preventing it to be known, because on my home computer there isn't this
problem, of course I'm not always home and travel a lot so I really needed
to find this work around.
This may help others possibly with the same problem, good luck to you all !
