samba - Feb 2004 - Security warning with XP clients and 3.0.2a PDC

Hi all,

I hope I don't make a prat of myself with my first posting...

I've got a 'niggle' with Windows XP Pro (SP1a) clients and 3.0.2a
PDC
(Slackware 9.1, 2.4.22).  Joing a domain, logging on etc is working
perfectly but I'm getting a 'File Download' security warning when I
try and
open an executable that's stored on the server. If I agree to open the file
it runs without a problem.

I had this problem with 3.0.1 but upgraded as a precaution.  I have not
experienced this with Windows 2K clients.

I've uploaded a screenshot of the error : http://www.sumlock.com/warning.jpg
smb.conf is attached (please feel free to criticise :-) )

I've been Googling and i've tried altering 'server schannel' but
i can't
stop the warning appearing.

Any suggestions for things to try (or even a guaranteed solution ;-) ) would
be very much appreciated.

Thanks

That affects logon credential checking, not file shares.

Try this as yes.

Good, but not required for this.
