samba - Dec 2001 - Samba221as PDC, who has working Config with 98 and 2K Clients ?

Hi,
I have a Samba 2.2.1a Server under SuSE 7.3 as a Domain Controller. It is no
Problem to connect to the shares from Win98SE and Win2000Pro within the Network
Environment. When Connecting, the Password is submitted and the Shares
(including the homedirectories) are available.
But because it is a PDC, I want the clients at boot time to connect and create
netvolumes with the logon.bat script.
Win98SE gives me the error "Invalid Parameter" ?!?!?! 
Win2000 says there is no machine account. But there is a machine account for the
computer. It is completly not working.
Has someone a working combination of Linux/Samba PDC with Win98SE and Win 2K
computers as clients? Maybe we could check against lower- and upperletter
spellings, config entrys etc.
Any help would be appreciated.
