Hi,
We have in our production farm three windows 2003 server web eddition
cluster.
At the begining (2-3 weeks) all was going smoothly. But, after a while
we started seeing the following event pairs in the 2003 System event
log:
Source: WLBS
Event ID: 1
Type: Information
Description:
----------------------
NLB Cluster : TCP DOS = 1.

Event ID: 1

Description:
----------------------
NLB Cluster : TCP DOS = 0.

----------------------
First comes the "TCP DOS = 1" and after a few seconds the "TCP DOS =
0".
Usually it doesn't effect the server's performance, but lately this
caused the server (each time different server) to stop participating
in the NLB cluster! On those occasions the difference between the "TCP
DOS = 1" and the "TCP DOS = 0" was 3 hours.
I couldn't find any information regarding TCP DOS event.
I will appreciate your help,
Thanks,
Robert
