Last Modified

Feb 22, 2014

Products (1)

  • Cisco Unity Servers

Known Affected Releases

5.0(1)ES70

Description (partial)

Symptom:

You receive the following pop-up, even though Unity is not in a 2008 domain or pointed to a read-only DC:

Cisco Unity requires read-write access to Active Directory, but the Cisco Unity server is currently communicating with a read-only Active Directory 2008 domain controller. Cisco Unity will not function properly until you run the DC/GC Reconnect Settings Tool to change the domain controller that Cisco Unity communicates with. For more information, see the help for the tool.

Conditions:

Unity 5.0(1) ES56 through ES74. 
Unity 7.0(2) ES7 or later

This can occur, regardless of the version of the domain controllers in your active directory in the following cases:

1. When you are logged on to the Cisco Unity server with a local administrator account. If you do not see any CiscoUnity_DSAD warnings and errors in Event Viewer, then you can safely ignore the error message. 

2. When you are logged on to the Cisco Unity server with a domain account, and Unity is unable to reach a DC, you will see event log messages similar to the following:
