USAGE:
Dfsutil /SpcInfo is a special problem diagnosis command that should only
be executed on the client. 

The SPC Cache keeps information about domain referrals for all trusted domains.
This information includes the list of domain controllers for domains 
that have been accessed. By observing the contents of this cache, an
expert user may deduct the DCs serving DFS paths that are accessed.
A '+' next to a DC name denotes the active DC.

Usage:
dfsutil /SpcInfo
