Cool, will keep an eye out - thanks again :-) ________________________________ From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Jim Harrison Sent: 09 August 2006 02:09 To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: RPC filter - connectivity changed 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.

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? ________________________________ From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Jim Harrison Sent: 09 August 2006 01:06 To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: RPC filter - connectivity changed 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".

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 :-\ JJ ________________________________ From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Ori Yosefi Sent: 08 August 2006 18:23 To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: RPC filter - connectivity changed 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. ________________________________ From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Jason Jones Sent: Tuesday, August 08, 2006 8:10 PM To: isapros@xxxxxxxxxxxxx Subject: [isapros] RPC filter - connectivity changed 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?
