Trouble with Windows 7 and Windows Xp Networking

I have a peer-to-peer network with Windows XP Pro pc's and 1 Windows 7 Pro pc. I have shared a folder and have given permission to everyone. Encryption was backed down and passwords were set to be unnecessary. User accounts for the workstations on the Win7 pc were set to unneeded. Connections were made and everything is good to go except the connection is slow. I changed the system to require user and password. Still slow. I installed a new nic. Still slow. What do I do next?

Mainly in the actual connection to the PC. There is a mapped drive(required for the software being used) and when the link is clicked on it takes up to a minute to open the link. After it is opened all seems well. Just for a test I clicked the up a level button and then went back in. Same slow connection. I disabled the nic and installed another one. Things seemed to be better but not much.

are there tons of FILES in the mapped drive (not folders)?  if so, your antivirus on the client machine (or serving machine for that matter) could be running a scan on every single file before it appears on the screen...  try temporarily disabling both antiviruses and see what happens

what connects these machines together... wireless?  a HUB?  a SWITCH? 15 switches?

I am afraid this is an issue that many people seem to encounter and which,for the time being,has no solution.It seems to me an encryption issue (W7 is taking too much time to authenticate files).I think M$ should look into this.

2 switches. I will try the AV option.

My customer was needing a resolution so we opted to downgrade to XP. Thanks for the comments.

The problem wasn't resolved, due to an upset customer, it was circumvented.
