Windows Server 2008 RRAS trouble

Hi all

I've a Windows Server 2008 SP2 (not R2) with two NIC that are connected to
two different subnet:

192.168.1.0/24 it is the office LAN
172.18.0.0/24 it is an intranet

this server acts as a router for the LAN's PCs for the route to 178 subnet.
Sometimes RRAS stop working and when thi happens:

into the NAT statistics windows I read no values but only dashes "-"
Restarting RRAS services has no effect, the event viewer logs this event:

ID 2016
Source: RemoteAccess
Unable to add the interface Internal with the Router Manager for the IPV6
protocol. The following error occurred: The parameter is incorrect.

The only way I have to restore RRAS is disabling and re-enablig RRAS! Please
help!

RRAS service is design for IPv4 protocol, please disable IPv6 protocol for
Internal interface. This post may help:
NAT stops functioning after a reboot -
