How to stop m/c checking for config.pol?

I have a W98 PC that I had to temporarily ‘join’ to a W2K domain in order to get some s/w installed. Now when users log on, they get an error message stating that they don’t have access to \\server\users\config.pol – OK clears it. I have never used the policy editor on this PC, so why does it now look for a policy file and how can I prevent this message?
