Yes,
1 go to Control Panel
2 click on phones+modems
3 click the modem tab
4 the modem should be listed there
5 if a modem is listed click properties
6(*) click query modem - this will send a series of messages to the modem to make sure it's vital signs are ok - it will tell you whether it passes the test or not .
(*) I'm not sure if there isn't another tab to be clicked at this stage - I removed my modem a week or so ago, laid to to rest next to an old VCR...
If the modem is not listed in 5 the driver for it can be re-installed from the win2k cd.
hth,
