why can't Server 2003 use a dial up modem



Master of my Domain
i know i know.... why the heck am i still using a dial up modem.???!!!

unfortuantely it's not because i'm nostalgic.... this crazy data processing center processes uploads data this way.

I'm using Windows 2003 Server... the modem seems to be working fine (it's an external 56k modem... it dials, screaches and seems to connect fine) but it doesn't "shake hands" with the dialed into computer/modem.

I was told this is a Win Server issue.... is this correct????? I tried 2 different external modems, and same problem, they would not connect.

It's not the phone line, because my laptop, which has a modem, connects fine using the same phone line.

any ideas???
