Where do you update the Mac OSX system properties that displays in Windows XP Network Neighboorhood 'Comments' section?

Does this help?

nope.  This is for setting up a Mac as a server.  Take a look at the doc attached to the question, I'm looking for the workstation side setting on a Mac OSX system for the equilivant of on XP under System Properties, Computer Name tab, Computer Description.  

since this changes every reboot, I wouldn't really call this a solution.  Are you sure there isn't another way of perminantly setting this value?

OSX does not really like you messing with SAMBA under the bonnet unless you know what you're doing.  It does the same rebuilds with Apache httpd.conf files after every reboot.

If you wish to tinker with SAMBA in the terminal I am sure you'll find a way of making that setting "stick" but as I mentioned there is no way of doing it in the OSX GUI.

Have you tried it already? I could only test it on 10.5.1, maybe 10.5.3 keeps this value after a reboot...

I haven't tried yet since the other recomendation stated it wasn't really recommended.  If there isn't a 'Apple' supported method to correct this I'll just close the question.  It isn't a problem as much as an annoyance.  BTW, I'm on 10.5.4.

It says "unless you know what you're doing" and that's exactly the point. If you look at the default smb.conf template that's available on OSX, there's a part in this file where it says "Make your userdefined modifcations below", so it's perfectly fine to add custom settings to this file.

The question is only if it honours global settings in this part as well and not just share level settings, so I'd give it a try and if it not works, revert to the original version of the samba template.

the setting change that applys to the machine name is only in the temporary generated file from the samba config, so it does reset on each reboot.  I did do the edits to verify.  Not sure if this will be resolved since it is really just a nusance item.  we can close this since we know where it comes from.

Oh, ok, that's bad, I thought that probably on 10.5.4 it would be possible to modify samba to honor this option.

Update: I stumbled upon the `defaults` command in the OSX terminal. I don't have OSX available at the moment, but you could try to look at the output of `defaults domains` in a terminal window to check wheter there are defaults for samba available too.

this doesn't 'stick' either.  This was more of a nusance than a problem, so we can go ahead and close this.  Just another example of Mac and PC not playing well together.  

The answers have been provided to the question in several stages.  The conclusion is that
YES, you can modify the Comments/Description but ...
NO they will not persist and get rewritten by OSX default Samba Configuration.
Sorry that jasonstockwell did not get a positive outcome but the answers are there nonetheless.  Suggest splitting the points between agriesser and eoinosullivan and closing.

as a body of work, agriesser and eoinosullivan did provide the right areas to look into the matter and expose where the changes could be made.  As a process of uncovering how it could be done if the OS didn't overwrite the settings on each new session, that was properly found. As a matter of technicailly resolving the issue, it isn't a resolution, but this thread should be closed as it is a function core in the OS and not an area that can be 'tweaked' or forced.  I'm fine with the participats receiving points for their input and investigations.
