When you try to reuse an "unavailable" drive letter for a different net
resource under Windows NT 4.0 or Windows 2000, error 1202: ERROR_DEVICE_ALREADY_REMEMBERED
appears.
CAUSE
A persistent connection becomes "unavailable" when it is disconnected using
WNetCancelConnection2 without updating the stored information about it.
Although the system allows WNetAddConnection2 to reuse an "unavailable"
drive letter for a different net resource under Windows NT 3.51, such
attempts are not permitted under Windows NT 4.0 and Windows 2000. This behavioral change is mainly due to concerns that the "unavailable" connection might have to be restored later by its dependent processes.
The change forces you to either use a separate drive letter for the second
net resource, or explicitly make the "unavailable" drive available for the
second net resource. The latter approach deletes the information about the
previous connection that is stored in the registry.
STATUS
This behavior is by design.
