How to debug Server crash?

My Server is freezing the Client connection almost every day somewhere betwen 11:00 and 13:00.

other services Web, SMTP , etc seem to be working.

When I send the ‘quit’ command it stops with pending nrouter, nserver and nservice (windows services).

I’ve to kill the servives. to restart the server.

What can I to debug this Problem?

PS - The only extra program I have is Panda Domino Secure
