Give up and be happy! ;-)

Just kidding... On Windows, file descriptors are called file handles and
include socket handles as well as files. The limit is supposed to be
around 16384 (on W2K server) but there may also be a limit on the number
of file handles that a process may have. Maybe using one of the
following tools will help identify which process is hogging all the handles:

Handle -- a command-line tool to report information about open file handles.
(http://www.sysinternals.com/ntw2k/freeware/handle.shtml)

Process Explorer -- a GUI interface tool that displays the number of
open file handles and more information about each running process.
http://www.sysinternals.com/ntw2k/freeware/procexp.shtml)

Unfortunately there's not a lot of information about tweaking these
limits. Most resources simply recommend changing the TIME_WAIT Timeout
value in the registry to increase the number of available TCP/IP
connections (http://www.winguides.com/registry/display.php/878/).

Other than that, Good luck!
