If your ISAPI extension uses synchronous WriteClient calls with large data buffers, there are following workarounds:

1. Increase the connection timeout value in the Web site properties on the server.
2. Use asynchronous I/O (note that this is only possible with an ISAPI filter or extension).
3. Call the various write methods with a small amount of data in a loop, and keep looping until all of the data is sent.

This is how it said in

Is there a timeout setting anywhere for and ISAPI.dll in IIS5.

We have an issue where the ISAPI request is made, the sever 
is trying to
write it to the client and it is timing out.
