SYMPTOMS

You use the Netsh utility to configure the Routing and Remote Access service for IPv6 routing and for IPv6 remote access on a Windows Server 2008-based computer. After you do this, the IPv6 connection protocol is not negotiated correctly. Therefore, the remote access client can only obtain an IPv4 address.

This issue does not occur when you use the Routing and Remote Access Microsoft Management Console (MMC) snap-in to manually configure the computer.

CAUSE

This issue occurs because the Netsh utility requires two separate commands to fully enable the Routing and Remote Access service for IPv4 or for IPv6.
