File and Printer Sharing from Client 98

NT 4.0 Server with WIN 98 Clients…The 98 Client wants to share it’s local printer to others on the network, it is setup for file and print sharing and is logged into the server, click on sharing tab in file or printer properties, tag as shared, click ADD to pull user list from server and getting the following error message: “You cannot view the list of users at this time. Please try again later.” All network settings have been double checked for correctness and browsing the Network Neighborhood works just fine. Any ideas ??????
