Err Msg: Secondary Interrupt Controller Detected...

Last reviewed: October 13, 1994

The information in this article applies to:

Microsoft Windows NT operating system version 3.1
Microsoft Windows NT Advanced Server version 3.1
Microsoft Windows NT Workstation version 3.5
Microsoft Windows NT Server version 3.5

SYMPTOMS

When attempting to run any application located on a Netware server by way of the Gateway Service for Netware, the Netware server may stop responding (hang) and display the following message:

   1.1.141 Secondary Interrupt Controller detected a lost
           hardware interrupt.

CAUSE

The Netware operating system displays this message whenever it detects a lost hardware interrupt. Lost interrupts occur when a driver or a board requests a service with an interrupt call and then drops the request before the CPU can respond to the request.

RESOLUTION

To avoid this problem, the following procedure is recommended:

Check for outdated drivers loading on the Netware server.
Unload all the drivers and reload them one at a time to isolate which driver (and/or adapter) is causing the problem. Then contact the vendor of the driver.
If the error is non-fatal, the message can be turned off by using the following command either in the STARTUP.NCF file or from the command prompt:
```
      set display lost interrupt alerts=off
```
