If an attempt is made to connect to a Distributed File System (Dfs) leaf a second time, the following error message occurs if the referral points to a Novell NetWare server:

This problem occurs because the Multiple UNC (uniform naming convention) Provider (MUP) is using the wrong redirector to process the request.
