SP2 messing with LAN connection - no receive

[Beaks]

OK heres my problem, i have 2 computers going via a router, from the computer that isn't sp2, i have no problems.

From the one i upgraded to sp2, i cannot receive any packets at all. I can ping the computer itself but cannot ping the gateway or beyond. I tried installing the sp2 fix kb884020 anf the fixreg.reg registry patch to no avail. I have tried setting static ip addresses for both computer and gateway and dns servers, again to no avail.

Before anyone suggests checking cables and other such suggestions, without touching anything but removing SP2, it works again, so its definately NOT hardware.

I tried plugging the WAN direct into the 2nd computer, again no luck.

Weird thing is, when i check my network connections details, my Physical address has changed to all FF's, which is probably the route cause of my problems. Removing SP2 changes it back to normal again.

I'm open to all suggestions.

You *have* turned off Windows Firewall I hope. If not, head over to the control panel, goto Windows Firewall, and turn that sucker off.

Yes, i use macaffee, but i turned all firewalls and a/v off.

if you are using other firewalls than what sp2 provides try uninstalling those and turning off windows firewall untill going then enable windows firewall.any other firewall you will have to configure

No, tried that, uninstalled Mcafee, reinstalled SP2, disabled windows firewall, still no receive??

Have you tried reinstalling your NIC driver?

Doesn't explain why removing SP2 makes it work, it uses the same driver.

Perhaps your NIC driver isn't compatible with SP2? I have heard that updating/reinstalling NIC drivers can solve SP2 network issues.
