Changing msExchAuthenticationFlags
Hi I run this VBS on test exchange 2003 server. http://technet.microsoft.com/en-us/library/cc785437(EXCHG.80).aspx I never meet service interruption after restart the IIS Admin service You can apply hotfix instead of vbs. To enable this authentication change on Exchange 2003 you need to either: Install http://support.microsoft.com/?kbid=937031 and then use the Exchange System Manager to adjust the authentication settings of the ActiveSync virtual directory. Or, set the msExchAuthenticationFlags attribute to a value of 6 on the Microsoft-Server-ActiveSync object within the configuration container on each Exchange 2003 mailbox server. An example script is provided at http://technet.microsoft.com/en-us/library/cc785437.aspx. http://blogs.technet.com/b/jribeiro/archive/2009/12/11/upgrading-exchange-activesync-to-exchange-2010.aspxTerence Yu TechNet Community Support

I see that I need to change this value and that there is a vbscript for that. My question is, how does changing the value effect ActiveSync devices? Will I need to reboot the server or restart a service? In other words, if I reset the value of msExchAuthenticationFlags, will there be a service interruption? Thanks.
