[Fog] Client Proxy Trouble

[tmleafs]

I have made like loads of images for fog in the 6 months of having it.

But there is one image (For the teachers) that will do this in the client log file.

I dont understand how one image (Teachers image) gets a proxy error but if I put another image (Pupils image) on the same computer it works. The only difference is that the staff image has SIMS. I will just make a new image but I want to get to the bottom of the problem as I know this problem is well known but never been fixed.

Is the fog servers ip address in c:\program files\FOG\etc\config.ini ?

Also, do the teacher's machines get a different set of proxy settings - which may require a user/passwd?
Might be set by a group policy or post install script?
This might be redirecting the fog service through a proxy, to which the fog service can't use to connect to the fog server (just a guess)...

I've had this error before!

We found BIZARRELY that using an IP address in the config.ini sometimes gives you this kind of hassle, from SOME machines!

Ensure your fog server has an entry in DNS and then give it a DNS name, then change your config.ini to use the DNS name instead. It works a charm for us (though WHY, we don't know!)

I have even copied a config.ini from a working image still does it. I have made 3 new images since posting the problem they all work fine. Will give the DNS trick a try if not will just have to make a new image i guess.
