Hi, I have a wireless LAN at home, my laptop is running Windows XP Home, and the other PC is running XP Pro. I have been able to access shared folders on the PC from the laptop for a while, then one day it suddenly stopped working. The network itself is working, but every time I try to access a folder across the network, a login screen pops up with the guest account as the username - greyed out and cannot be changed. When I try to access the entire network, I get a message that I don't have the permissions to access the workgroup "MSHome". Any ideas? Thanks!
