coneecting to webfolder (wd4111) not possible

I installed WebDav Server which works fine on the server (create webfolder connection), but from my WinXP Home Edition and Win2000 clients I get a message “unsufficient memory…”, even from a clean started machine. But using WinXP Pro does work (strange!).
From the other clients I can go to the WD server with IE, so WD is running.
Any ideas?
