The KB is in final edit review and will be part of a hotfix rollup
that's hitting the streets "RSN".
I can't be any more specific because I don't make those decisions.
It won't do any good to ask PSS now because the fix isn't ready for
public consumption.
I can't speak to "PSS awareness", since it depends on the engineer you
talk to and his (her) relative familiarity with ISA hotfixes.
The Kb will be public, which means you can self-discover.

Thanks Jim.
Any chance you can elaborate?
Probs bring this up in my ISA DR PSS call (other post) - will PSS be
aware of this KB? Any idea of an ETA?

There are issues with Exch and ISA if client connections are abruptly
terminated that can cause this behavior
Keep your eyes open for a KB that quotes "RPC" and "Keep-Alive".

Thanks Ori - kinda how I expected the alert to be.
I get the ISA alerts 2/3 times every couple of weeks and lots of event
log errors, saying "RPC server available", then "RPC server unavailable"
in a complete loop. The only way to solve the issue is to reboot all
array members - ouch! Whilst ISA is in this state all existing MAPI
clients remain working, but all new sessions fail.
However, I can see no reason why the Exchange server (the RPC published
server) should suddenly appear unavailable - I also cannot see why the
destination server is at fault if a reboot of ISA fixes the problem.
Kinda feels like ISA is getting confused to me :-\

This alert is issued when a published RPC server has gone offline / came
back online.
When attempting to establish a connection with the RPC server, if the
connection attempt fails (for the first time) then this alert is issued.
Later on, when a connection attempt is successful (for the first time)
then this alert is issued again.
HTH,
Ori.

Hi,
Anyone seen the "RPC filter - connectivity changed" ISA alert? Under
what scenario does this get trigged?
Is this an ISA problem or an indication that the published RPC server is
at fault?
Cheers
JJ
