Internet connection

[GMANJOHN]

I recently upgraded my cpu(XP@2500+, biostar mb ) and after I had it all together with a new WD HD 80gb, I installed my generic 56 k intel chipset modem and all seems fine, but when I connect to the internet it loggs on and disconnects and says can't connect with server, I've tried several isp's with the same problem...any ideas??
Thanks GMANJOHN

P>S> I can fax, so the modem works.
Thanks again
