I have a windows 2008 R2 server with RRAS setup on it.  I need to go in and change the configuration within RRAS.  When I try to go into the the "Config Routing and Remote access" I get this message and am not sure what it is asking me to do first....

The message ==> Incoming connections are currently enabled on Servername.  Before you can configure RRAS on servername, you must open network connections and delete Incoming Connections.

I don't have a lot of experience with 2008 R2 and am now sure where to go to do this???/

It sounds like you have ICS (Internet Connection Sharing) enabled on the network adapter. If so go to network connections and right click on each adapter and choose properties. See if there is a "Sharing" tab next to The Networking tab. If so select it and make sure "allow other users to connect through this computers Internet connection" is unchecked.

Make sure you are not using this service to share the internet connection before disabling. It may have been set up intentionally to act as a gateway. A better option is to use RRAS to do this than ICS as it offers more options and control.

Yes, ICS is checked in each of the adapters, but grayed out so I cannot uncheck it.  I verifed that the ICS service is disabled and not running....

Any ideas?

Multiple NIC's? SBS 2008 will not support more than 1 NIC.
Can you post the results of ipconfig /all and route print please.

That configuration looks fine.
Sorry about earlier comment; "Multiple NIC's? SBS 2008 will not support more than 1 NIC." I had assumed SBS version for some reason. No problem on 2008/R2 server std.

Is there any chance the adapters are bridged? Right clicking on the adapter/s should show the option and if enabled.
The only other thought I have is the following services need to be enabled to enable ICS. I wonder if any were disabled if you could not disable ICS. Perhaps try starting any of these services that are not running, just as a test to see if you can disable ICS.

Application Layer Gateway Service
DHCP Client
DNS Client
Internet Connection Firewall Internet Connection Sharing
Network Connections

The other thing that is interesting is ICS usually will set the LAN adapter in the 192.168.0.0/24 subnet. This is not the case so I am wondering if ICS is really not enabled.

The adapters are not bridged and ICS is disabled at the service level in windows.  I did try to start it and got the error:

"The Internet connection sharing (ics) service on the local computer started and then stopped.  Some services stop automatically if they are not in use by other services or programs."

Do I need ICS started to change the RRAS config???  

I am thinking that punting and deleting the whole thing and recreating it may be the best way to go...

Thanks for your help

No, Default is disabled.

If you don't have any elaborate RRAS configurations I agree. Right click on the server name in RRAS and choose disable. When you do the same and choose enable it should be a clean slate. Don't so so in the services management console though as this just stops and starts the service.
