How to delete the prefix of network driver?

Hi
We use "net use" command to map shared folders of server to network driver
in client computer. If client computer is Windwos XP, there will be a prefix
before the network driver name like" 'Beijing File and Print server
(cnbei2s05)' ", I noticed that string is the combination of server's computer
description and computer name. Because that string is too long, I want to
delete it. But after I deleted the server's computer description and rebooted
it. there is no any change of this prefix. I tried search that string at
register, also did not found. I am sure that string come from server's
computer description and there is a copy on somewhere, such as in Active
Directory. There is no BDC also.
So where this prefix string?

Many thanks for your help!!
