Firewall blocking the TCP 443 response? Adam F ________________________________ From: Jonathan<mailto:[email protected]> Sent: 6/3/2014 12:44 AM To: [email protected]<mailto:[email protected]> Subject: [Exchange] Event ID 11 with Source MSExchange Web Services Hi - new to this list, though I was on the Sunbelt lyris list years ago. Have not been active in a couple of years. I'm hopeful someone here can help me out. My Google-fu is failing me.... I have [inherited] two Exchange 2007 Servers running SP3 with the latest rollup (I got them updated from SP2 back in October) these servers are in two separate sites. Each server holds all the roles, and we're just passing HT traffic between. Each sends their own email out their local connection, but all inbound traffic comes in through Site1. The mailboxes are split about 50/50 between the two servers. Anyway, we have been receiving the following event on both servers for some time. We are NOT getting event ID 17 on either server (as just about everything I've googled turns up). on each server, the event says "none of the CAS servers in [the remote] site are responding". If you have any suggestions on how I can resolve this, I'd be very grateful. Event Type: Error Event Source: MSExchange Web Services Event Category: Core Event ID: 11 Date: 6/2/2014 Time: 9:58:19 PM User: N/A Computer: EX01Site1 Description: CAS server EX01Site1 failed to proxy EWS to AD site CN=Site2,CN=Sites,CN=Configuration,DC=DOMAIN,DC=CORP because none of the CAS servers in this site are responding. Please check the configuration and status of the servers in site CN=Site2,CN=Sites,CN=Configuration,DC=DOMAIN,DC=CORP For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. -- Jonathan, A+, MCSA, MCSE
