I have two Windows XP computers connected through an Ad-Hoc network, computer A creates the network and B connects to it. Both computers are on the Mshome network and have file and printer sharing enabled, and they can ping one another through the adhoc network.

The result is that computer A can see computer B, but B cannot see A in the workgroup. But when A tries to access B I get a "you might not have permission to access" error telling me to contact the administrator.

I tries to google the error, but most posts talk about problems connecting different versions of Windows to each other. I tried turning off the firewalls on both machines and checking if the required services are running. Nothing helped.

Please excuse my ignorance on Windows networking, I haven't used Windows in around 10 years.
