After dialing up on my modem, and then disconnecting, the computer soon gives the following message:

TAPISRV caused an invalid page fault in
module KERNEL32.DLL at 017f:bff9dfff.

Afterward, everything seems fine with the computer.(For instance, I can connect again with no problems.) However, the computer will not shut down properly. It hangs at the "Windows is shutting down" screen. Instead of choosing "Shut Down", however, "Restart" executes with no problem.

I had this problem while running WinME with a PCI Lucent LT Winmodem. I eventually reformatted the hard drive and installed Win98SE and changed the modem to an ISA USRobotics Hardware modem. The same problem soon started. I sometimes do not even have to dial-up. After a reboot, the error sometimes just pops up randomly. Also if some program wants to connect to the internet and the dialup screen appears and I hit Cancel, the error pops up soon afterwards.

I recently installed Virtual Private Networking and now get a similar error upon exiting that:

MPREXE caused an invalid page fault in
module KERNEL32.DLL at 017f:bff9dfff.

I am not sure, but maybe this is related: A while back, I changed my hard drive to an IBM 75GXP UltraATA100 60GB. I don't think I had the problem with my older HD. I have an ASUS P2B motherboard, which only runs at ATA33 (I think). I will try turning DMA off and see if that fixes the problem. (I would hate to lose DMA though!)

QUESTION ?? Has anyone found fix for it yet.
I have also tried the rebuild of the telephon .ini --- no luck

I have uninstalled Media player altogether, and still Tapisrv crashes. Before that, I tried the fix that Shawn references, and that didn't make a scrap of difference.
