MSDLC T1 Timer Does Not Back Off (124343)
The information in this article applies to:
- Microsoft LAN Manager 2.2
- Microsoft Windows for Workgroups 3.11
This article was previously published under Q124343 SYMPTOMS
When a link is lost or temporarily unavailable, Microsoft data link control
(MSDLC) clients retransmit frames at the default value for T1, rather than
backing off exponentially.
CAUSE
This problem occurs due to an error in the MSDOS-based version of MSDLC
algorithm for backing off the T1 timer.
STATUS
Microsoft has confirmed this to be a problem in MSDLC. A fix to this
problem is in development, but has not been regression-tested and may be
destabilizing in production environments. Microsoft does not recommend
implementing this fix at this time. Contact Microsoft Product Support
Services for more information on the availability of this fix.
NOTE: Although T1 will back off exponentially after installing this hotfix,
by specification, it is not allowed to exceed the current value of Ti.
Therefore, if the value of Ti is set low, T1 will only back off until
doubling it again would cause it to exceed Ti.
