What I've found...

    I was using     ErrInfo = WNetCancelConnection2("U:",0,True).

    This was removing the "mapping" of U: in Windows Explorer, but the
connection was still active.  I've changed it to use the NetR.lpRemoteName,
and this cancelled the connection.  So, this problem was resolved.

New problem...I can double click on "Network Neighborhood" and get to a
particular lan by keying in the id "kcmsgo" and the password "kgeaug98" (as
stated above) and this works fine.  However, this API call
WNetAddConnection2 (above) works on some lans and not on others.  The double
clicking, in Network Neighborhood, works on all of the lans.  I'm getting
Error Code of 5 (Access denied).  I don't understand what is happening
different between Windows Explorer (Network Neighborhood) and the
WNetAddConnection2 API call.

Any help would be appreciated.

Thanks!
