I'm runnig SLackware 10 with Samba 3.0.20b (I thought that my problem will be gone when I update samba- wrong

)
PDC is up and running.. there are mobile profiles - partially.. becouse only for windows 9x, I don't want any other systems to have those roaming profiles.. and I don't have :P but on win2k I get something strange.. the "login path" in smb conf is empty (to disable roaming profiles) and also the "logon drive" is empty.. but that win2k is mapping as Z drive the "login home" directive (which in every tutorial and book is said to be only needed by win 9x).. Any ideas how to change this?
One more.. how to make samb run a logon script only on win2k? I know about %a but don't know how is win2k recognized as.. and teher is somthing in man page that it might be also not recognized.. :P
Any ideas??
