XP Mode slow copying to host

First I found this, which seemed to work: (the registry change should be done on the host (Win7) machine, not the XP machine)
Workaround for Windows VPC networking slowness between host and guest

Then a coworker showed me how to disable this without the registry edit:
Start->Control Panel->Network and Sharing Center->Chagne Adapter Settings->Dbl-click 'Local Area Connection'->
Properties->Configure->Advanced-> Disable TCP Checksum Offload and UDP Checksum Offload (one each for IPv4 and IPv6)

This worked for me. I hope it helps you.

Jeff,
Thanks I will try that. Do you happen to know if it affects anything in Windows 7??
I am not really sure what I am doing when I disable those settings.

You know, it must effect something. But my coworker says they set it all the time in certain situations. I haven't noticed any ill effects since I made the change. I googled a bit trying to find what it really does and only found others asking the same question!

Thanks, actually I was told by someone who knows a lot more than I do that the setting if disabled will have the cpu do the checksums instead of the nic card. He said in his opinion it would only make a difference in very very large data transfers.

So thanks I am going to do it and I can always change it back if I see any problems.
