I am having problems using WNetAddConnection2 to map an existing drive.
If I use explorer to disconnect the drive I can remap another with out any
problems.  I have tried using the WNetCancelConnection2 command and it
breaks the network connection but the mapping remains and I can not change
the mapping.  What I am trying to do is write a program to check the drive
space of all our servers and I believe I need a drive mapping to use
DiskSpace and DiskFree.  So, in order to do this I have to remap a local
drive many times.  Thanks for any help or let me know if I am doing this
all wrong.  This is going to run on a Win95 box or maybe an NT4.0 box.

I don't know if this is going to help, but...

I found that it sometimes takes a little time to cancel the
connection, so you might try:

var
 Success: integer;
begin
 repeat
  Success := WNetCancelConnection2(PChar(Drive), 0, False);
 until Success = NO_ERROR;

Sorry to follow my own post but I have more info.  The error that I get is
ERROR_DEVICE_ALREADY_REMEMBERED.  How do I "unremember" it.  Thanks.

Well, the error is reporting exactly what you are seeing: the drive
letter is still assigned to the network connection, even though the
connection itself has been closed.

Are you passing the CONNECT_UPDATE_PROFILE flag when you call
WNetAddConnection? As I understand it, this causes the mapping to be
'remembered'. Try 0 instead.

Alternatively, try passing that same flag when you cancel the
connection. That might cause it to be 'unremembered'
