Okay folks after digging searching and screwing around with the the
registry and System Policies and going over the XP issue (which was the
base starting point for me to investigate the W2K SP4 issue)

Anyway the solution is ALMOST the same but not exactly. The registry
entries that must be changed are as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Netlogon
\RequireSignOrSeal

Set dword to a value of 0

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Netlogon
\SignSecureChannel

Set dword to a value of 0

(NOTE: There is no registry entry for "CompatibleRUPSecurity" in W2K do
not bother with it.)

On the W2K SP4 client go to Start "Run" and type in gpedit.msc

Go to the following (Note: the problem was that the entries here do not
match those of XP PRO and it took a little digging to find them.)

Computer Configuration >> Administrative Templates >> System >> Logon

Look for:

"Do Not Check for Ownership of Roaming Profile Folders"

and:

"Add the Administrators security group to roaming user profiles"

Both of these need to be enabled

I reset my profile directory on the Samba Server back to 'root' ownership
the way it's supposed to be and restarted the W2K system and logged on
without any problems.
