The Network Policy Server Service (IAS) Fails to Start or be Installed
[Today's post comes to us courtesy of Damian Leibaschoff and Wayne McIntyre]
We have seen some cases where the Network Policy Server service fails to start, when this happens, functionality provided by TS Gateway (used in RWW) or Routing and Remote Access (RRAS) will also stop working. Furthermore, we’ve also seen, that as part of the troubleshooting, partners are uninstalling the entire role, and when trying to re-install it fails.
How to identify you are experiencing this issue?
When starting the NPS service it fails with:
The following event is logged:

The problem can happen when the NPS service tries to register it’s VSS writer and finds that it does not have enough rights to do so.
To resolve this:
Check the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\VssAccessControl
Verify that the setting for NT AUTHORITY\NETWORK SERVICE is set to 1. If this is set to 0 change it to 1.
Open Task Manager, select Show Processes for all users, and kill any instances of IASHOST.EXE that might be running.
Start the NPS Service. (If it is not installed, re-install it at this point)
We are investigating why the value would be 0 instead of 1. At this time we have identified that uninstalling WSS 3.0 will cause the value to change to 0, there are other interactions that could lead to this value getting changed. We will update this post once we have more information.
