Win2003 IPSec VPN Keeps Stopping and Not working

We set up a VPN from a win2003 box to a sonicwall pro 300. We used the security policy to set up IPSec. This works great, but very often -- usually in middle of the night each night, it loses connectivity and stops working. When we unassign/reassign the policy it all goes back to normal. Is there any reason for this or any way to fix this and prevent it from happening?

What do your logs show during the time frame in question? Also, what version of firmware is on your sonicwall?

windows logs show nothing---
sonicwall is version
i can dig through sonicwall logs, but what am i looking for? it seems to be negotiating a connection every couple of minutes--- so there is a lot of data to search through

your VPN tunnel's have a set time that they will stay open for. they will not try to reform automatically unless you tell them. This is probably what's happening.
