OK - Hi all
I have an irritating problem with a cluster and perhaps some of you can
short circuit it for me...

Environment
    Windows Server 2003
    Sql Server 2000 EE - SPK 3
    3 node stretch cluster - only 3rd node is stretched

Problem Summary...
Node 1 (lets say 10.0.0.1) is ocassionally losing it ability to repond to
ping/name resolve. Trace route is failing one hop before reaching it.
However if we fail over to node 2 and back again all is ok for a random
period of time and then it fails to respond again
We are now leaving Node 2 as the Active node and witing to see if it happens
on node 2 also - if it does then I imagine the stakes will rise considerably
;-(

Things to Date...
All resources seem to be correctly configured and assigned to the correct
groups
The IP address is correct and unique for the SQL V Server resource
All n/w cards are functional
Nothing obvious in the event logs
The node responds to a ping locally (that is from Node1 over an RDP
session) without resorting to failover even though it is failing from an
external ping.

Other...
Not sure if this is related but at installation time I could not build the 3
nodes at once. I had to build Node 1 then add Node 2, then add Node 3.
Probably a red herring

Anyone ever have this or shed any light.
Should I be talking to the networking geniuses?

Thanks in advance

Barry Lynch
