I need a little networking help.

I have 5 workstations, DSL modem and a network printer running thru a router/switch/firewall.

All PC's have XP Pro with SP2.

4/5 units have no issues.

Unit 5 can access all other units but the others cannot access unit 5 in the Network Neighborhood. All units are under the same Workgroup.

When trying to map to unit 5 - a username/pass request comes up - there are no passwords on any unit.

Group Policy - Network Access - Sharing and Security model for local accounts

4/5 units have the Guest Only- local users authenticate as guest - option set

Unit 5 has - Classic - local users authenticate as themselves - option set and is greyed out with no option to change.

This explains why unit 5 can access the network drives but the others cannot access unit 5.

Network printer works fine 5/5.
Internet works fine 5/5.

Any ideas on how to remedy this problem - I am stuck.
