Symptom 1
On a Windows Server 2003-based computer that is running Microsoft Internet Security and Acceleration (ISA) Server 2004, the following event is logged in the Application log every 49.7 days: Event Type: Error

Event Source: Microsoft ISA Server Control

Event Category: None

Event ID: 14079

Date:

Time:

User: N/A

Computer:

Description:

Due to an unexpected error, the service fwsrv stopped responding to all requests. Stop the service or the corresponding process if it does not respond, and then start it again. Check for related error messages.

Note This event is logged multiple times.

Additionally, the Isasched service may be affected. The following event may be logged in the Application log: Event Type: Error

Event Source: Microsoft ISA Server Control

Event Category: None

Event ID: 14079

Date:

Time:

User: N/A

Computer:

Description:

Due to an unexpected error, the service isasched stopped responding to all requests. Stop the service or the corresponding process if it does not respond, and then start it again. Check for related error messages.

Symptom 2
On a Windows Server 2003-based computer that is not running ISA Server, a similar problem occurs when the following conditions are true:
 * You call the CreateTimerQueueTimer function repeatedly in an application.
 * You set a specified period to trigger the timer that is created by the CreateTimerQueueTimer function.

Note The specified period should be less than 10 minutes.
 * The application runs for more than 49.7 days.

After 49.7 days, the timer is triggered immediately instead of being triggered after the specified period. After several minutes, the timer is triggered correctly.



CAUSE
This problem occurs because of the mathematical error in a kernel timer manipulation. ISA Server uses a timer to monitor the Firewall service. Other applications that use a timer that is created by the CreateTimerQueueTimer function may also experience this issue.
