'Unable to Initialize KRNL32.EXE' Error Message on Terminal Server with Internet Explorer 4.1 (268825)


The information in this article applies to:

  • Microsoft Windows NT Server 4.0 Terminal Server Edition
This article was previously published under Q268825

SYMPTOMS

When you run Internet Explorer 4.1 on a computer running Microsoft Windows NT Server 4.0, Terminal Server Edition, after you install the Windows NT 4.0 Option Pack, the following error message may appear:
MDM.EXE - Unable to Initialize KRNL32.EXE

CAUSE

This behavior occurs because Windows NT 4.0 Option Pack is not supported on the Terminal Server Edition of Windows NT 4.0.

WORKAROUND

To work around this behavior, use Internet Information Server 3.0, which comes with Windows NT Server 4.0, Terminal Server Edition, for Web server functionality on the Terminal Server.

MORE INFORMATION

Windows NT 4.0 Option Pack is not supported because neither Internet Information Server 4.0 nor Microsoft Transaction Server functions correctly when installed on a computer running Terminal Server. Customer applications that require these Option Pack technologies may not function properly either when they are installed on Terminal Server.

Site Server also is not supported on Terminal Server.

The error message states that Machine Debug Manager (Mdm.exe), which is used by the Microsoft Visual Studio in Internet Explorer to debug ActiveX scripts, is not working. Because the script debugging tool is not supported with Terminal Server, it should not be installed. If you did install it, follow these steps to remove it:
  1. In Control Panel, double-click Add/Remove Programs.
  2. Click Windows NT 4.0 Option Pack, and then click Add/Remove.
  3. Within the setup program, click Machine Debug Manager to uninstall it.
