System consists of 6 PCs authenticating to an SBS server.
5 people can login to any of the 6 PCs and access the server files. 1 person can login to 5 of the PCs and access the Server files. On the sixth PC the user can log in but when they try to access files on the server via Windows Explorer they get the see network admin you may not have permission error message.
I have checked IP addresses (DHCP), pinged the server etc. Everything looks OK. Why can a particular user not access the server from this PC whilst OK from others?
