After windows 7 installation was added to the domain, i often keep getting the BSOD on the AFD.SYS file. My windows firewall was on, but trying with it off. I also find that having the wireless network card enabled also produced blue screens.
This issue that afd.sys cause blue screen occurred on my Windows 7 x86 and Win 7 x64. Asus P5KC MB, 4GB Ram, Intel CPU E6750 Duo.
Here is how to fix the issus. Solved it for me.
1.Disable my onboard NIC (Atheros).
2.Used Broadcom PCI-E NIC. .
Or you can try to use different hardware.
