Adding Multiple DC's to Unity 4.0 system

Answered Question

I have a unity 4.0 system and want to add multiple DC's to the unity server. On the unity server there appears to me a field to enter a 2nd DC but it is grayed out. I have done some research and it appears this is not a license issue.

I have this problem too.

Actually the DC/GC Reconnect Tool only allows you to configure the DC/GC that Cisco Unity's directory Monitors (AvDSAD and AvDSGlobalCatalog) use to synch with Active Directory.

In the situation you describe where messages are not delivered after a reboot of the DC, I have to assume the DC is also a GC, you would want to look at the GC that MAPI is using, not the DC/GC that the directory monitors are using.

See the following:

Ah... yeah, you'll need to manually edit the registry:

Hope that helps,

Yep, that's where the DC/GC Reconnect Settings tool comes into play as I discussed.

Hi,

If you're referring to the DC/GC Reconnect Settings tool, in order to cause the Manual Primary and Manual Secondary fields to become active, you need to uncheck "Enable Automatic server search functionality on reconnects for this domain". It'll then allow you to enter values into each field.

Hope that helps,

Brad

Sure, providing the DC/GC is reachable in a timely fashion, there should not be any interruption of service if all goes as planned with the switch to the backup.
