[Samba] Problem logging on to pde

[Alex]

Samba-3.0.0beta2-1

I'm trying to log on from win2k(sp3)/winxp(sp1) computers to my samba pdc,
but i'm not succeding,
I'm getting this error from windows while trying to do the initial login as
root:
"windows cannot find the network path"

from samba.lo:
[2003/07/19 17:05:28, 1] sam/idmap_tdb.c:db_idmap_init(487)
  idmap uid range missing or invalid
  idmap will be unable to map foreign SIDs
[2003/07/19 17:05:28, 1] sam/idmap_tdb.c:db_idmap_init(499)
  idmap gid range missing or invalid
  idmap will be unable to map foreign SIDs

these two messages repeat itself three times every time someone tries to log
on.
xp/win2k does find the domain, it's just that i cannot do the initial login:
