DirectAccess TCP/IP Error

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:

Component Name
Last Process Time
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
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 between 2/20/2011 4:22:04 PM and 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:


  SupportInfo1 1
  SupportInfo2 3961
  ProcessingMode 0
  ProcessingTimeInMilliseconds 1482
  ErrorCode 1062
  ErrorDescription The service has not been started. 
  DCName \\
  ExtensionName TCPIP
  ExtensionId {cdeafc3d-948d-49dd-ab12-e578ba4af7aa}

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! Smile
