[Samba] suddent random problem with Windows boxes

[Matt Singerman]

Hello all,

I am not a Samba expert by any means, so please bear with me if I make a fool 
of myself.

We run a small network in this office.  There is a Windows domain running off 
of a Debian Linux server, running Linux 2.4.25.  There are mostly Windows 
2000 and Windows XP machines, but there are still a few users clinging on to 
Windows 98 (this is because they run specialized testing software that does 
not work in 2000 or XP).  Starting a few days ago, anyone who tries to log 
onto a Win98 machine gets the following error:

"The domain password you supplued is not correct, or access to your logon 
server has been denied."

In addition, a few Windows 2000 users have suddenly lost network access, being 
told that they do not have permission to access their roaming profiles.

I have made absolutely no changes to the server or Samba in a few weeks, so I 
don't know what could be causing this.  I was running Samba 2.2.9pre1, so I 
upgraded to 3.0.6 to no avail.

Here is a copy of my smb.conf file (which was last modified on July 30th):

Oh, and of possible interest: there is nothing in log.smbd about the Windows 
98 logon attempts.  I mean NOTHING.  Not even a failure notice.

Any and all help and suggestions would be greatly appreciated.  Thanks!
