A DHCP client receives a "Duplicate name on the network" error message when
logging on to the network.
Also, the Enable IP Routing check box in the TCP/IP properties of the
Network Control Panel tool is checked, but is unavailable and cannot be
cleared.
CAUSE
If Remote Access Service (RAS) has been installed, in addition to
another network protocol, and then removed or disabled, the registry
entries may not be automatically removed.
RESOLUTION
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
- If RAS is still installed, remove it using the Network Control Panel
tool, under Installed Network Software.
- Start Registry Editor (Regedt32.exe) and go to the following subkey:
\HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
\Tcpip\Parameters
- Change the 'EnableIpRouting' value to 0.
- Restart the computer.
The computer will now only request an IP address for the installed network
interface.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5 and
3.51. We are researching this problem and will post new information here in
the Microsoft Knowledge Base as it becomes available.
