Mapping a drive will not connect to network

I have two new pcs in our network. I am having intermitten problems getting
them to map a drive. These are XP machines and a 2003 Server....the following
is the procedure followed and then the dialog box that shows up....

Map Network Drive>Select Letter>Browse>Browse for Folder>.....when I try to
expand the domain to see all the pcs on the network I receive the following
message.....

(server name) is not accessible. you might not have permissions to use this
network resource. Contact the administrator of this server to find out if you
have access permissions.

HUH?!!?!?!?.....User has permission because user has already mapped other
drives....nothing has changed on user's pc or on the server regarding
permissions..

Any clue why all of a sudden this started??

TIA

It could be the name resolution too. This search result may help,
