Roaming Profiles / Wrong permissions? Strange Behaviour...

Hi, got some problems with roaming windows profiles.

Server: XServe G5 | Mac OS X 10.5 | working as PDC
Client: Windows XP Professional SP2

1. I'm able to connect with Windows-Client to PDC, newly created folders (e.g. on Desktop)
are stored in the profile, also files / programs within this folders - when user logs off
files and folders are stored properly.

2. When I try to get the same profile at a second Windows-Client the profile could not be
loaded because of that created file within that folder (1.).

I get an Windows-Error-Message: "Error performing Inpage Operation"

That only happens because of the saved /created files in the new created folders. When I create a folder, without saving a file inside, it works without problems. Profile settings are loaded properly.

Here is the content of my samba config (with testparm) , hope that helps - I didn't make any modifications to that file manually. Would be really nice to get help with that strange behaviour.
