If it worked on the primary thread while being derived from CDialog, it
would seem it should work on the secondary thread unaltered, but: I would
derive your networkServer class from CWnd instead of CDialog, and create
it by calling CWnd::Create() in your CWinThreadDerived:::InitInstance().
networkServer performs initialization requiring the HWND in the OnCreate()
method.

Further, optimally (but optionally) create the CWnd as a Message-Only
Window. From
http://msdn2.microsoft.com/en-us/library/ms632599.aspx#message_only:

message-only window enables you to send and receive messages. It is not
visible, has no z-order, cannot be enumerated, and does not receive
broadcast messages. The window simply dispatches messages.
To create a message-only window, specify the HWND_MESSAGE constant or a
handle to an existing message-only window in the hWndParent parameter of the
CreateWindowEx function. You can also change an existing window to a
message-only window by specifying HWND_MESSAGE in the hWndNewParent
parameter of the SetParent function.
