Nonpaged Pool Memory Leak

Hi

I am having Windows 2003 with service pack 1 installed. I need to reboot my
server every 2-3 days because the nonpaged pool exhausted. When the nonpaged
pool hits about 250MB, the server will not be able to create anymore network
connection.

After running poolmon.exe, I found that "afdP" is the cause of the memory
leak. After doing some search, "afdP" tag belongs to AFD.sys. Does anyone
know how to solve this problem?

I am suspecting it has something to do with using asynchronous/unblocking
TCP sockets.

I don;t knoiw if you've attempted to search for this or not yet, but I did
and got a few hits. Instead of me weeding thru them, maybe you can weed thru
them and pick out which one more closely addresses your specific scenario:
