Problem description:

The windows socket function GetHostByName for some unknown reasons was slowed down after a KB update microsoft put out in december 2006.

Workaround:

Cache that info! I create a thread upon application startup or initialization, that returns the value asynchronously.  IP and network name are not subject to change too often.
