It's not a network, but this board seemed the best place for my question. I'm having a couple of problems which appear to be related to the modem itself. The most significant of which is that the Windows will sometimes crash to a BSOD with the following error message: Driver_IRQL_not_more_or_less_than ***STOP: 0X000000D1 (0XFEC09000,0X00000002,0X00000000,0XF884EDA3) ****ACFVA.SYS - Address F884EDA3 Base at F884D000, Datestamp 3D2A1E19 The only thing that I have been able to decipher from this is that ACFVA.SYS is a modem file. Anybody know anything more about this? The other problem is that while my connection to my ISP remains active, the ability to receive data soon reduces and/or quits, requiring me to disconnect and redial. Again, I hope someone knows something about this.
