Disable Redirection

Affected Systems:

Microsoft Exchange Server 2010
Microsoft redesigned the way in which Exchange Server manages traffic. The following ws_rep.cfg file property is used to control network traffic redirection on these Exchange systems.

Property

Value

Purpose

ExDisableRedirectDNS

True (default setting)

False

When set to True, disables DNS redirection and skips SPN redirection in the event a switchover occurs. Switchover itself occurs as expected.

When set to False, the Exchange Management Console on the new active server is not started after switchover.

When set to True, the Redirect DNS property is hidden in the Network Traffic Redirection group on the Arcserve RHA Manager screen.

Set this value to True for Exchange Server 2010 HA scenarios.

Microsoft Exchange Server 2013
When you have not configured the Network Load Balancing and the CAS role is used for the master, then you have to enable the Redirect DNS option. To enable the Redirect DNS option, set the Redirect DNS option to on from the Network Traffic Redirection property in the High Availability Properties dialog.
