Do you have "persist-tun" and "persist-key" in the client config file?

Have you tried other "ip-win32" methods?

Make sure the DHCP client service is always running.

You might try adding "show-net-up" to the Windows config.  It will show 
OpenVPN's view of the interface and routing table at the point of failure.
