This one gave me a headache yesterday:

Last updated version of KB824141 hotfix on a Windows 2000 workstation in
a domain with Samba PDC has the following consequences:

1. When a user with a mandatory profile logs on, it doesn't load the
profile correctly. The cached profile looks like a default profile -
empty directories except for the NTUSER.MAN. No Desktop, no Application
data ... nothing. A verbose USERENV.LOG gives a nice list of dirs and
subdirs added and reconciled with result [OK]. But they are not there!

2. If the patch is installed without SP4 being installed it raises the
Roaming Profiles Security problem (normally raised by Windows 2000 SP4)
(see http://support.microsoft.com/default...b;en-us;327462),
but does not install the corresponding "Do not check for user ownership
of Roaming Profile Folders" local group policy in the administrative
templates.
