From: Don Pedro on 4 Jun 2010 12:22 Hi all, We have 2 CAS servers we need to shut down for the weekend. When I shut them down, activesync stops working. Neither of these CAS servers are the internet facing one. CAS01 - internet facing one. Configured with internal and external URL. CAS02 and CAS03 configured only with internal URL. When CAS02 and CAS03 are shut down, activesync stops working and the following event is logged on CAS01 "The proxy request to CAS02.contoso.com has timed out" When I power back up the 2 CAS servers, mail starts to sync again. Now I know this is due to proxying on CAS01. How do I tell CAS01 to not proxy while these servers are down? Hope this is clear. thanks in advance

How do I tell CAS01 to not >proxy while these servers are down? Are CAS01 and the other two servers in the same AD site? CAS01 will only talk to a mailbox server in the same AD site, otherwise it will either redirect the request (if the other site has an external url) or proxy it to another CAS in the same AD site as the mailbox server(s). --- Rich Matheisen MCSE+I, Exchange MVP |
