When you try to connect to a shared folder, you may receive the following error message:
No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept
This behavior occurs because one or more programs connect to and disconnect from the shared folder on a short cycle, especially when the disconnect and reconnection time to the shared folder is less than one second. In these circumstances, the disconnected session does not have sufficient time to expire before the new connection is made. As a result, there may be several disconnected sessions that are waiting to expire. These sessions count toward the maximum number of connections for the shared folder until they expire.
