ISA/TMG de Exchange Listener Connection TimeOut Degeri

20 / 01 / 2011 by ISA Server & TMG, TMG Yorum yok / No Comments
Exchange 2007/10 kullanirken asagidaki gibi bir uyari Event Log’unuzda beliriyor ise
Event ID: 1040, MSExchange ActiveSync

The average of the most recent heartbeat intervals [443] for request [Ping] used by clients is less than or equal to [540].

Make sure that your firewall configuration is set to work correctly with Exchange ActiveSync and direct push technology. Specifically, make sure that your firewall is configured so that requests to Exchange ActiveSync do not expire before they have the opportunity to be processed.

For more information about how to configure firewall settings when using Exchange ActiveSync, see Microsoft Knowledge Base article 905013, “Enterprise Firewall Configuration for Exchange ActiveSync Direct Push Technology” (

Bunun sebebi ISA/TMG de kullandiginiz Web Listener’in varsayilan Connection TimeOut degerenin 1800 sec’e ayarlanmis olmasi, bu durumda ya Sync klasoru altinda bulunan Web.config dosyasindaki asagida gozuken yerleri degistirmelisiniz yada

“MinHeartbeatInterval” value=”60″
“MaxHeartbeatInterval” value=”3540″

ISA/TMG sunucunuzdaki Listener degereni benim tavsiyem ISA daki Listener Connection Timeout degerini degistirmenizdir, bunun icin ISA/TMG sunucunuzda Exchange icin klullanmis oldugunuz listener ozelliklerine girip, Connections tabinda Advanced Settings’i secip 1800 olan mevcut degeri Exchange ile eslemek icin 3540 seklinde degistirmeniz yeterli olacaktir.
