I have a machine running windows XP professional and it is unable to access the file server. It can access the router and the web but not the file server. The work group has 5 machines on it but the 6th cannot access it and i am unable to get a opportunity to put a password / user name into it as I get the error message the workgroup is not accessible contact your administrator

can someone advise what steps i am not doing to access to file server
