Somewhere along the line, upgrading from UAG SP1 RC to SP1 I’d managed to hose my laptop; the infrastructure tunnel was never coming up and IKE Main Mode negotiation was failing. Connecting the client to the LAN and refreshing Group Policy I ran into an error concerning TCP/IP. Looking at the GPRESULT output:
| Group Policy Infrastructure | Success | 2/20/2011 4:22:04 PM | ||
| Registry | Success | 2/17/2011 9:40:53 AM | ||
| Security | Success | 2/17/2011 9:40:54 AM | ||
| TCPIP | Failed (no data) | 2/20/2011 4:22:04 PM | ||
There was nothing in the Application Event Log. The System log, however, had an Event ID 1085 listed. The Details tab gave a clue: EventData SupportInfo1 1 |

It turns out the IP Helper service had been set to Disabled . Setting the service back to Automatic and rebooting the system, updating Group Policy and everything is back to normal.
Weird!

Thanks a lot Mylo. I had the same issue, and couldn’t get to the root cause. This is exactly what I needed!
Ditto, implementing DISA STIGs and came across this error. Your blog post is the only place with the fix. Thanks!
went nuts trying to find what gp setting it was.
set everything to not configured and it still gave the error.
IPhelper service was the trick
thank you
Wish I know why it does this.
My tcpip settings are default not configured.
TCPIP Success (no data)
vs
TCPIP failed due to the error listed below.
The service has not been started.
Additional information may have been logged. Review the Policy Events tab in the console or the application event log for events
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Tcpip]
If you have that key and its blank as with this
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Tcpip\CurrentVersion]
delete them error is gone
and delete this from gpt.ini located in C:\Windows\System32\GroupPolicy
