Mac Forum / Applications / Virtual PC / April 2007

I have Vista Ultimate x86 on a nForce 590 AMD SLI platform. After installing
and running Virtual PC 2007, during boot up, it will cause network driver
malfunctions (according to Vista diagnosis). Basically after restart, my
network is down. Sometimes I can reboot and get it back, other times it will
be down for numerous reboots until it finally works. I know it's not the
network hardware or drivers themselves as I have had no problems whatsoever
until after installing VPC2007, and even then it may or may not show up on
the first restart, plus I can load in safe mode w/networking and it will work
fine.

I have tried all of the different nForce drivers, both direct from nvidia
and from MS update. I have experienced this on both x86 & x64 Vista Ultimate.
This most recent time is on a fresh install that has been clean of VPC and
stable for 3 weeks solid, and this problem came up after VPC2007 install (and
this was the only software, driver or other install for the past two days).

So I have uninstalled VPC2007 and the very next boot, my network is just
fine. So I'm 100% sure that VPC2007 is causing the problem with the network
drivers during startup in Vista Ultimate.

Has anyone experienced this? Does anyone have any suggestions on how to fix
this? I really need to have VPC2007 running on my machine, but I can't go
through this round and round of never knowing if it will kill my network the
next time I reboot.

Thanks for your help.
