Troubleshooting Active Directory Connectivity

The Vocera Voice Server sends an email alert whenever there is a problem with the connection of one of the Active Directory configurations (whether the connection is enabled or not). The following table describes the Active Directory email alerts/warnings:

Table 1. Active Directory alerts and warnings
Alert/Warning	Description	Corrective action needed
Active directory connection for < Active Directory Configuration Name> failed.	The Vocera Voice Server connection to the Active Directory configuration failed, whether one or multiple servers are specified, including primary and secondary servers. By default, a new alert is sent every 30 minutes until the Active Directory connection is restored.	Work with IT to ensure that all Active Directory domain controllers are running. Once Active Directory domain controllers are running, the Vocera Voice Server will automatically connect to one of them. You don't need to disable and then enable the Active Directory configuration in the Administration Console.
All primary Active Directory domain controllers for connection < Active Directory Configuration Name> are down. Now connected to <Secondary Active Directory IP Address> (Secondary server).	The Vocera Voice Server connection to the Active Directory has switched from a primary server to a secondary server. By default, another email alert is sent every day until the connection to a primary server is successful.	Work with IT to ensure that a primary Active Directory domain controller is running and is accessible over the network. Once a primary Active Directory domain controller is running, do this: Disconnect the Active Directory configuration. If the configuration is currently enabled, disconnecting it also disables it. See Connecting to and Disconnecting from an Active Directory Configuration. Connect the Active Directory configuration. If the Active Directory configuration was previously enabled, enable it again. See Enabling and Disabling an Active Directory Configuration.
