TITLE   :Error Message When Opening Rascfg.dll During DUN Installation
PRODUCT :Microsoft Windows NT
PROD/VER::4.0
OPER/SYS:
KEYWORDS:kbsetup dun kbDialUp

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Server version 4.0 
 - Microsoft Windows NT Workstation version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you click Install after starting Dial-Up Networking for the first time, you
may receive the following error message:

   Noncritical error:

   An error has occurred

   Unable to open the file RASCFG.DLL

   A noncritical error has occurred. You may retry the operation, ignore it or
   exit the entire setup operation.

If you click Ignore, the error is repeated for all subsequent Microsoft Remote
Access Service (RAS) files. If you click Retry, you are still unable to install
Dial-Up Networking.

CAUSE
=====

The contents of the Oemnsvra.inf file, which is located in the
%SystemRoot%\system32 folder, have been modified.

RESOLUTION
==========

Use the expand command to expand the original Oemnsvra.inf file from the
Microsoft Windows NT source CD-ROM into the %SystemRoot%\System32 folder. For
example, go to the appropriate directory on the CD (i386 for Intel computers),
and type the following command:

   <Drive>:\I386>expand Oemnsvra.In_ %SystemRoot%\System32\Oemnsvra.Inf

where <Drive> is the letter of your CD-ROM drive.

MORE INFORMATION
================

After you have restored the Oemnsvra.inf file, you are able to complete the
installation of Dial-Up Networking.

Note: Be sure to reapply your current Windows NT 4.0 service pack prior to
restarting your computer after you complete the Dial-Up Networking installation.
