DOCUMENT:Q108737 07-JAN-1994 [W_NT]
TITLE :Err Msg: Cannot Allocate a ROUTE for User Connected on COM...
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:
--------------------------------------------------------------------------
The information in this article applies to:
- Microsoft Windows NT operating system version 3.1
- Microsoft Windows NT Advanced Server version 3.1
--------------------------------------------------------------------------
SYMPTOMS
========
When a Remote Access client calls a Windows NT Remote Access Server (RAS),
the following error message appears:
The remote access server cannot allocate a ROUTE for user connected on
COM port [port #].
CAUSE
=====
This error message appears in the error log if the Windows NT (or Windows
NT Advanced Server) Remote Access Server is configured with TCP/IP but NBF
has not been installed to prevent NetBEUI frames from getting onto the
local area network (LAN). However, Remote Access Service for Windows NT
requires that the NBF (NetBEUI) protocol is installed.
RESOLUTION
==========
If you do not want to put any NBF NetBEUI frames on the remote LAN at all
and only allow TCP/IP frames to get onto the wire, but still use NBF for
RAS, then you can unbind NBF from the network card. This allows RAS users
to still call in through RAS because the dataflow direction here is from
the RAS NDIS driver to NBF. Unbinding RAS from the network card only
prevents the flow of data from NBF down to the NDIS driver for the network
card.
To unbind the Remote Access Service from the network card on the Remote
Access Server, do the following:
1. In the Control Panel window, choose the Network icon.
2. Select Bindings.
3. In the Show Bindings For field, select Remote Access Server Service.
NOTE: In the listbox below the all lines involving the "Remote Access
Server Service" will appear.
4. Select the line:
Remote Access Server Service -> Netbeui -> [Name of adapter] Adapter
Driver -> [Name of adapter] Adapter
5. Choose the Disable button at the bottom of the dialog box and choose the
OK button.
6. In the Network Settings dialog box, choose OK.
7. In the "You must shutdown and restart your computer so that the change
you made will take effect" dialog box, choose the Now box or the Later
box.
For more information on hiding protocols and disabling bindings, see the
Windows NT 3.1 Remote Access RASREAD.TXT file in the SYSTEM32\RAS directory
and the Microsoft Windows NT Advanced Server "System Guide."
