Unable to open Folders on WinXP SP3

Hi There.

I just setup my MBLD & now i’m not able to open my folders. It keep asking for username & password. When entered, it says " \Networkdrive\folder is not accessible. You might not have permission to use this network resources Contact the administrator of this server to find out if you have access pemission.

Multiple connection to a server or shared resources by the same user, using more than one user name, are not allowed. Disconnect all previous connection to the server or shared resources & try again "

What can be the cause of the problem 7 how can my manage my private folders with specific users?? 

Apparently you are doing multiple connections

make sure no other folder has been accessed with that computer

disconnect any mapped locations and map the desired folder
