hi,
only if you first unmap the drive that is currently connected..
something like this:

first it checks who is connected then if not \\server3\f_drive then disconnects them and maps server3\f_drive instead.


procedure TForm1.Button3Click(Sender: TObject);
var
NetResource: TNetResource;
buf : array [0..100] of char;
i :cardinal;
 begin
i := 100;
wnetgetconnection('K:',buf,i);
if buf = '\\server2\C_drive'
then begin
label1.caption :=
'unmapping drive cause its not server3\_f_drive';
if not
WNetCancelConnection2('K:', CONNECT_UPDATE_PROFILE, True) <> 0
then label1.caption :=SysErrorMessage(GetLastError);
NetResource.dwScope      := RESOURCE_GLOBALNET;
NetResource.dwType       := RESOURCETYPE_DISK;
NetResource.dwDisplayType := RESOURCEDISPLAYTYPE_DOMAIN;
NetResource.dwUsage      := RESOURCEUSAGE_CONNECTABLE;
NetResource.lpLocalName  := 'K:';
NetResource.lpRemoteName :=
'\\server3\F_drive';
NetResource.lpComment    := 'For testing purposes';
NetResource.lpProvider   := '';
WNetAddConnection2(NetResource,'','',CONNECT_UPDATE_PROFILE);
   end
else if
 buf = '\\server3\F_drive' then
label1.caption :='k: is already  mapped to \\server3\F_drive';
end;

hope it helps some
Regards Barry

sorry this line should be changed :
if buf = '\\server2\C_drive'
to something like
if not buf = '\\server2\C_drive' ...

esk, you can try to call 'net use * \\myserver\myDir' via Createprocess or ShellExecute, this will try to connect you to NEXT AVAILABLE local driver letter
