Access Violation in RRAS When Windows Time Service Adjusts System Time (222077)
The information in this article applies to:
- Microsoft Windows NT Server 4.0 Terminal Server Edition
- Microsoft Windows NT Server 4.0
This article was previously published under Q222077 SYMPTOMS
On a system with Routing and Remote Access Service (RRAS), the following symptoms
may occur as a result of a negative system time adjustment.
- Mpradmin.exe may display an Integer Overflow exception error message (status code 0xC0000095).
- You may not be able to stop Mprouter.exe and it stops accepting new RRAS connections.
CAUSE
Both symptoms are caused by an arithmetic calculation for call duration that can generate
a negative 64-bit result that causes an integer overflow when saved in a 32-bit integer format.
This behavior occurs only if the time adjustment is negative and sufficiently large enough
to move the system clock back to a time prior to the beginning of any RRAS connection.
Time adjustments are caused in a variety of ways. Manual time correction through the
System Time tool in Control Panel is a potential source, as are automatic mechanisms
such as the intrinisic OS operations that periodically synchronize the system time
to the CMOS clock resource. Domain-based Microsoft network time services can similarly
cause this problem. Additionally, third-party programs that synchronize the system clock
to a network-accessible reference clock can act to stimulate this problem.
