I recently installed win 2000 professional on a client in the office. We have an NT server. I am unable to map shares on the rom server from the 2000 client. Every time I attempt to map a share I get an error message that reads "The mapping network drive cannot be created because the following error has occurred: an unexpected network error has occurred" I am able to map the shares on win 95 & 98 clients. I am an administrator of the 2000 client. I have upgraded the 2000 client to sp2. I want to upgrade all clients to win 2000 as soon as I can get this to work. Help on the matter would be greatly appreciated.
