I had this problem about a year ago, when providing my sister with a facility share a dial up modem initiated by either system (one XP and t'other "98). Posed questions on some forum, and tried looking into all the listed programs and Windows Scheduler to no avail. It seemed that the dialling system was the W98 system (the modem was on the XP system). If you find the answer I would be interested to know the answer - at the moment my sister just leaves th emodem off, until chosen to dial! Yeh, I know, broadband is ONE answer!
