I am using Windows 2000 professional and have written a program to transfer data via the Winsock control using the UDP protocol. After sending a large file, I can no longer see the internet. Internet Explorer stops working, and all of my chat programs drop connection.
When I look at the task manager, I don't see the program running... usually to get my connection back I have to completely reboot the computer. Any ideas as to why I am dropping connection? Thanks.

Well, if you added a line "winsock1.close" somewhere in there then that will drop your program's connection. I can't see why you lose everything else though. Later,

Found out the source of the problem. My router would drop me if it got flooded with large UDP packets. When I connect directly to my cable modem I am able to transfer data pretty well.
Turns out my firewall drops me if I send a large number of packets over around 60k. This is true even of TCP connections. Heck, it even dropped me when I pinged it with 64k of data. This is hardly optimal........
