Above is a sample of logs from the "messages" log file.  We have a network with Windows XP systems (SP2) and patched for all critical updates.

The distribution of Linux we run is Red Hat Enterprise ES 4.0.  The samba server has been configured as a domain controller (without LDAP).  Of late we have observed that Windows XP client systems are posing problems while logging on to the domain.  After entering the username and password, some client systems get stuck at the stage of "Loading Personal profile" and do not proceed further.  Of course, we have figured a way out by unplugging the network cord and logging on and then connecting the cord so that the server can be accessed.

Can someone provide a hint or a solution to solve this problem?

Please refer to this answer fromone of our experts:

I think your Windows XP clients and RedHat samba server are trying to negotiate protocols using different and mismatching ports  
and that's why you have to unplug and reconnect network cables
in order to skip protocol negotiation ( Error: getpeername failed. Error was Transport endpoint is not connected )

Also , try adding the following to your smb.conf file:
 smb ports = 445
(the default is smbports = 445 139).

 Among the new ports used by Windows 2000, Windows XP and Windows Server 2003, is TCP port 445 which is used for SMB over TCP.

The SMB (Server Message Block) protocol is used among other things for file sharing in Windows NT/2000/XP. In Windows NT it ran on top of NetBT (NetBIOS over TCP/IP), which used the famous ports 137, 138 (UDP) and 139 (TCP).
 In Windows 2000/XP/2003, Microsoft added the possibility to run SMB directly over TCP/IP, without the extra layer of NetBT. For this they use TCP port 445.

The error messages got cleared out.  But the original problem of Windows XP hanging while loading the profile continues.  

Below is the smb.conf file for reference:

        log level = 1
        log file = /var/log/samba/%m.log

        smb ports = 445
        time server = Yes

Sure there's problem.
You have to define user profile location on your samba server, so Windows XP
will try to locate user profile (data stored in NTUSER.DAT ) on the server.
A user profile (userprofile, or simply profile is configurated when used in-context) is a feature of the Microsoft Windows operating system, comprising a given user's collection of personal documents and settings on that computer. At first logon, a folder will typically be created under "Documents and Settings" matching the logon-name of the user.
So you need to add {profile} seciton in your samba configuration file.
In the [profiles] section the path variable tells where the profiles are to be placed and make sure the directories are created with right names and permissions.

[profiles]
create mode = 0600
directory mode = 0700
path = /home/samba/profiles/
profile acls = yes
read only = no
writable = yes

Also you may want to tweak a liitle bit more {homes} section of the config file
In the [homes] section the following entries are important :

[homes]
comment = Home Directories
browseable = no
writable = yes
valid users = %S
read only = no
create mode = 0600
directory mode = 0700

logon home = \\your_samba_server\%U //  (This tells where is the user home directory )

hide files = /*.pst/

Nope, I tried adding those sections in the smb.conf file.  But this simply did not work.  Any other suggestions?  Do you require any logs or other information to troubleshoot further?

I was able to figure out the problem.  The NTUSER.DAT file under the netlogon folder had a problem.  I have replaced the file and things are working fine now.
