Proxy error

Hi,

I have a user at a remote site that is having problems with configuring
various IM clients and GoToMyPC. The machine currently has internet access
and email access. It is running XP Home SP2. While each of these works
fine, whenever a he tries to set up the above he gets a proxy error message.
I don't have the exact error yet but was hoping for some quick pointers on
where to look for a problem. I've had hime turn off the windows firewall
and there are no others installed. GoToMyPC would not even install because
of this error so I can't logon remotely. The machine is connected via a DSL
modem.

Thanks for any pointers.
