SNMP SysUpTime Counter Resets After 49.7 Days

• Microsoft Windows NT Workstation versions 3.51, 4.0
• Microsoft Windows NT Server versions 3.51, 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When using SNMP to monitor sysuptime (system up time), the counter will be reset after 49.7 days or 4294967295 milliseconds.

CAUSE

MIB_II.MIB (RFC 1213) specifies sysUpTime as TimeTicks. SMI.MIB (RFC 1155) defines TimeTicks as having a max value for 4294967295. This is the number of milliseconds that this counter can hold. This also corresponds to about 50 days, this is why the counter resets back to 0.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
