Hello, I have a 831 VPN user that has just changed ISP's from Comcast to Verizon. Her new connection comes up and the VPN connection looks good on our 3005 concentrator. Her 7960 IP Phone works fine but none of her Windows PC's seem to work correctly. The PC's take forever to boot up and once they do, they cannot browse the network and connect to M$ Exchange. IP pings work fine as well as the IP Phone. Nothing on the VPN has changed except now the connection is NAT-T. I have onther 831 users that are working fine with NAT-T.
I did not run the SDM Security function on this router.
Any Ideals?
Thanks, HARRY
