Hi, I recently installed an Iomega zip drive on an NT4 workstation (SP6a). The install went fine, but stopped the modem (USR Winmodem internal) in the middle of a connection. When I rebooted the modem was gone, and the RAS service would not start. I subsequently removed the Iomega software and disconnected the drive, but still no joy. I initially installed the zip disk to backup information on the box, now it can't connect via dial-up. The event logs don't say jack. I think that it may be related to a memory address or IRQ conflict. Can anyone offer any guidance on this problem please? Any help appreciated.
