XCLN: Cannot Delete a Network Connection After Inserting File

SYMPTOMS

You cannot delete a network connection that has a reference to a file that has been inserted into a message in the Exchange client. When you try to delete the network connection from a DOS prompt you will receive this error: " There are open files on the connection. Close all files and quit all programs related to the connection before you try to delete". There is more help available by typing NET HELPMSG 2404." If you try to disconnect the drive from file manager, you get this error: "There are currently files open on <drive>: connected to \\server\share. If you do not close the files before disconnecting from the network device, data may be lost. Do you want to disconnect the device anyway?" and you are given an option to disconnect the drive.
