Unable to start RRAS; Event ID: 20103 - Unable to load C:\Windows\System32\iprtrmgr.dll

We have SBS server 2011 running OWA / RWA successfully.
VPN was additionally setup on the server, and was working OK.
Recently we configured NIC teaming on the server and since then, we have been unable to connect to VPN.

We have attempted to restart the RRAS service and received the following errors:

"An error occurred while trying to start the Routing and Remote Access service on <HOSTNAME>. For more information about the error, see Event Viewer. (Right-click the My Computer icon on your Windows desktop, and then click Manage. In the Computer Management console, click Event Viewer."

“Routing and Remote Access cannot be started because of the following error. Please see the event lof for more information:
The serve has returned a service-specific error code. (8007042a)”

Following this article from error 8007042a:

.. we attempted to rerun the VPN wizard but received the following Error:
Virtual Private networking is not set up. Ensure that RRAS is installed and running, and then rerun this wizard.

As previously stated, RRAS will not start.
We removed Network Policy and Access Services role (including RRAS), and rebooted the server, however Network Policy and Access Services remained installed in server roles after the reboot, with the following error:

Log Name:      System

Unable to load C:\Windows\System32\iprtrmgr.dll.

As in the following article, I’ve followed the suggestions KB 299013, and the registry key is present with correct values:

we have not reinstalled / reset TCP/IP as this is currently a production environment.

Remove RRAS and reinstall RRAS.


That should fix it.

Have you tried dropping the nic teaming, deleting the rras config that you did?

That might fix the unable to make changes. You may then team the nic's and try to setup rras again.

SBS does not support multiple NIC's or NIC teaming.  Enabling these will cause wizards and some features to fail.

Having stated the above; "Also SBS will be a single nic server. Teaming of nics is not supported.  ....but.....   If you want to team the nics, don’t team them, run the wizards, then re-team them."
from the SBS 2011 build doc
http://social.technet.microsoft.com/wiki/contents/articles/1906.i-overview-of-sbs-2011.aspx

This would suggest disable RRAS, run the fix my network wizard, team the NIC's, then run the SBS VPN configuration wizard (not the RRAS wizard).  However that is interesting as the Fix My Network wizard should fail with multiple (un-teamed) NIC's.

Correct! Nic teaming not supported and messed up the RRAS.. we've just settled with the RWA / OWA as this suffices
