Network problems after installing Lion on one of three computers

I installed Lion on my MacBook Pro, but left Snow Leopard 10.6.8 on my MacPro and iMac. Then I could no longer connect for filesharing from my MacPro or iMac to the MacBook Pro. I could go to the base folders, including Applications, but I could not access my User folder, even though all the Sharing settings remained the same. However, I could connect from my MacBook Pro to the other two just fine. It appears that the Snow Leopard machines cannot make the connection with the Lion machine. But the Lion machine can connect to the SL machines. This means that I can get my File Sharing done, but it would be more convenient if I could use my MacPro as the central machine.

I have no problems with any of my machines when I connect to the internet or printer through my local network.

I've tried unbinding the sharing and redoing the preferences in the Sharing pane, but the situation stays the same. I've rebooted all three machines a few times. I've run maintenance procedures.

When I boot the MacBook Pro with a Clone of the whole disk from before the installation of Lion (so that the MacBook Pro is once again running on Snow Leopard 10.6.8), I have no connection problems.

There's something that needs fixing in the Snow Leopard/Lion interface when one is Sharing files.

MacPro 2.66mhz 7GB RAM, MacBook Pro early 2008 4GB RAM, old Intel iMac, Mac OS X (10.6.8)

I tried lots of the above, nothing workied until I removed the Home folder sharing. BTW, both lion, each computer has an Admin account and a Standard user account. Could connect and share with the admin account but not the Standard account until I removed the "home" folder sharing.

Seems to be fixed by 10.7.1.

10.7.1 does not fix this on my Mac Pro and Mac Mini.

The only thing that works, ist, turning off AFP and turning on SMB Sharing.

Does anybody know if using SMB causes any issues? What about missing .DS_Store oder Resource Forks (if they still exits at all :-)

I found the problem on my computers:

Since several OS releases, I always made an update, but never did a clean install. A clean install makes no problem, so I searched for the part of the lion update, that leads to the network problems.

It was simple:

I did a clean install on a second drive. The I startet the migration assistant. marked every point exept the computer settings

After the migration was finished, I entered the network settings manually and everything worked.

This worked for me! OS Lion upgrade made my wi-fi disconnect when my computer was idle. I left for some errands and 4 hours later, I'm still connected! Thanks!
