SYMPTOMS
========
Some DOS commands and 16-bit programs may not run from a command prompt. For
example, if you type the dir command, and then press ENTER, nothing is displayed
as shown in the following example:
C:\> dir
C:\>
CAUSE
=====
This behavior occurs because the ComSpec system environment variable is not
pointing to a valid location for Cmd.exe file. Command.com is dependent on the
Cmd.exe file. If you move or delete the Cmd.exe file, you will encounter this
behavior.
RESOLUTION
==========
To resolve this behavior, run Cmd.exe from the location to which you moved it,
or update the ComSpec system environment variable to point to Cmd.exe.
To update ComSpec on a Windows NT 4.0-based computer:
1. Click Start, point to Settings, click Control Panel, and then double-click
System.
2. On the Environment tab, click ComSpec.
3. In the Value box, type the location of the Cmd.exe file, and then click Set.
The default setting is: %SystemRoot%\System32\Cmd.exe.
4. Click Apply.
To update ComSpec on a Windows 2000-based computer:
- Click Start, point to Settings, click Control Panel, double-click System, and
then click Advanced.
- On the Environment tab, click ComSpec, and then click Edit.
- In the Variable Value box, type the location of the Cmd.exe file, and then
click OK. The default setting is: %SystemRoot%\System32\Cmd.exe.
MORE INFORMATION
================
This problem can occur after following the steps that are described on the
following Microsoft Web site:
Microsoft Internet Information Server 4.0 Security Checklist
(http://www.microsoft.com/technet/security/iischk.asp#28)
In these directions, it is recommended to move the Cmd.exe file to a different
folder to make IIS more secure.
