[Samba] preexec close + Win2K

I have Samba 2.2.2 on Solaris 8 acting as a PDC. I
have written a script that checks to see if a user is
already logged in on the PDC and if so, sends the user
a message (via the SMB message stuff) telling them
they need to log off. I run this script using
"preexec close" under the netlogon share. So, the
user authenticates against the PDC, but then gets a
desktop that is mostly useless if they are already
logged in elsewhere.
With NT clients, the client gets four message boxes.
This works well enough.
However Win2K clients just keep trying and trying, and
the user gets an
endless stream of the message boxes, about one per
second.
Is there anything I can do (either on the Win2K client
or on the server) that
would keep the Win2K client from trying again and
again to mount netlogon? I
want it to give up, but it won't.
Here's the ol' testparm dump:
