Removing or Adding a CD-ROM into Drive May Cause Errors When Running MacAfee's Netshield

ID: Q160794

The information in this article applies to:
  • Microsoft Windows NT Workstation version 4.0
  • Microsoft Windows NT Server version 4.0

SYMPTOMS

The following errors may occur while removing or inserting a CD on a computer running Windows NT 4.0:

System Process - No Disk
-or-
STOP: 0x0000000A
IRQL_NOT_LESS_OR_EQUAL
The "System Process - No Disk" error may occur when Windows NT is upgraded from version 3.51 to 4.0 if NetShield is installed prior to the upgrade.

The "STOP 0x0000000A" may occur when changing CD-ROMs, particularly the auto-starting disks, such as the Windows NT 4.0 or Windows 95 setup media.


CAUSE

Services for McAfee's NetShield for Windows NT are running on the server computer. Different versions of NetShield yield different errors. NetShield versions 2.5.1 and 2.5.2 are not compatible with Windows NT 4.0.


RESOLUTION

Set the McAfee Task Manager services to disabled. If the STOP errors prevent access to the server, do one of the following:

FAT Partition

  1. Boot to DOS using a bootable DOS disk.


  2. Rename the directory where NetShield is installed. This will cause the services not to start (because they could not be found) and allow you to log on to the server.


NTFS Partition

  1. Install a parallel copy of Windows NT into another directory.


  2. Boot to the new installation of Windows NT.


  3. Rename the directory where NetShield is installed. When you boot back to the original installation, this will cause the services not to start (because they could not be found) and allow you to log on to the server.


Emergency Repair Disk

Run the Emergency Repair Disk and replace the Software and System registry hives.

NOTE: Replacing the Software and System hives will return the system registry to when the ERD was last updated. If the ERD was updated after McAfee was installed, then this method will not resolve the issue.

If the ERD was created at the time of the Windows NT installation and not updated after hardware and software installations, then the system will revert to the registry at the time Windows NT was installed.
