Default VPN disconnects what's changing the routing tables?

I'm having an issue on my own telecommuting link that takes me down 4-5 times per day.
I'm using the Nortel Contivity VPN client, and get error messages that the "routing table has changed" and disconnects.
Were a small company, the network person is on vacation, and I'm finding the following in the VPN client logs:

4/2/2013 9:58:26.883 [ENGS] -I-VerifyServerIsAlive: ISAKMP had traffic (after keepalive).
4/2/2013 9:58:27.383 [ENGS] -I-VerifyServerIsAlive: Set receivedData FALSE.
4/2/2013 9:58:28.555 [ENGS] -I-Protocol not recognized - message dropped.

4/2/2013 9:58:44.586 [ENGS] -I-Protocol not recognized - message dropped.

4/2/2013 9:58:49.586 [ENGS] -I-Enter: DynamicDnsCleanup.
4/2/2013 9:58:49.586 [ENGS] -I-Routing tables changes violate security policy.
4/2/2013 9:58:49.680 [GUIW] -I-Received tunnel down message from engine.
4/2/2013 9:58:49.695 [GUIW] -E-VPN tunnel is disconnected due to routing table change.
4/2/2013 9:58:50.179 [GUIW] -I-Received idle message from engine

( I bolded the statement to show where I believe the problem is coming from)

What process/machine is identified by [ENGS] ? I'm a sales guy, so not too techy.....My end device at home is a Cisco Linksys WRT160nv3, and its not enabled for DDNS, so where is the cleanup command coming from?
Any help is appreciated.....

It's probably the metric of the wifi wireless interface that is changing. Windows does changes it when the signal strengh change.

Search for bug wi00568576 Wireless users are disconnected intermittently.

That should have been corrected in 10.04.108.
