SYMPTOMS
In Microsoft Windows CE .NET 4.2, a remote server is no longer available when a network connection over a wireless LAN is stressed.



CAUSE
This problem occurs because only four NetBIOS LANA slots can be used. When up-down notifications are asynchronous, a race condition occurs. In this race condition, the down notification may complete before the up notification. This behavior wastes one of the buffer slots of the redirector. As soon as all four slots are taken, you can no longer connect over the NetBIOS implementation.
