Problem

When users access Cisco Unity ViewMail for Outlook (VMO), some users receive a popup that requests username/password/domain. This happens every time the users try to access voice mail through VMO. In this scenario, the workstation in which the issue is observed is in the same domain as the Unity server.

The popup appears as this example shows:

Solution

VMO uses Distributed Component Object Model (DCOM) to communicate with the Cisco Unity server. You need to use DCOM to authenticate to the Unity server in order to play the voice mails.

This problem might arise if some software is installed on the affected workstations which, in turn, might have disabled DCOM. It has been found that many Antivirus updates disable DCOM.

Complete these steps in order to fix this problem:

1. Run DCOMCNFG from a command prompt.

2. Click on NO for all of the DCOM configuration warnings.

3. Once the Distributed COM Configuration Properties dialog box appears, click on the Default Properties tab.

   Note: You can also complete these steps in order to navigate to Default Properties:

   1. Under Component Services, click on Computer, then right click on My Computer, and select Properties.

   2. Click on the Default Properties tab.

4. Place a check mark next to Enable Distributed COM on this computer.

5. Under Default Distributed COM Communication properties, select CONNECT for Default Authentication Level and IDENTIFY for Default Impersonation Level.

6. Click on OK.

7. Reboot the machine.
