You cannot determine the BlackBerry Attachment Connector that the BlackBerry Enterprise Server or the BlackBerry MDS Connection Service uses

If you install a BlackBerry Enterprise Server, the setup application also installs two BlackBerry Attachment Connector instances automatically. One of the BlackBerry Attachment Connector instances connects the BlackBerry Enterprise Server to the BlackBerry Attachment Service. The other instance connects the BlackBerry MDS Connection Service to the BlackBerry Attachment Service. During the installation process, the setup application gives both BlackBerry Attachment Connector instances a name that includes the computer name (for example, <computer_name>_AC).

The BlackBerry Administration Service displays the names of both the BlackBerry Attachment Connector instances. By default, you cannot determine easily which instance connects to the BlackBerry Enterprise Server or the BlackBerry MDS Connection Service, so you can change the display names of both the BlackBerry Attachment Connector instances to make them easier to identify.

1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > Attachment > Connector.
2. Click one of the BlackBerry Attachment Connector instances.
3. On the Instance information tab, locate either the MDS Connection Service Instance name section or the Email (Exchange) Instance name section. Consider the following naming conventions:
   • If you locate the section that is named MDS Connection Service Instance name, the BlackBerry MDS Connection Service connects to this BlackBerry Attachment Connector instance.
   • If you locate the section that is named Email (Exchange) Instance name, the BlackBerry Enterprise Server connects to this BlackBerry Attachment Connector instance.
4. Click Edit instance.
5. Perform one of the following actions:
   • If the BlackBerry MDS Connection Service connects to the BlackBerry Attachment Connector instance, in the Instance information section, in the Friendly description field, type a unique name (for example, <server_name>_AC_MDSCS).
   • If the BlackBerry Enterprise Server uses the BlackBerry Attachment Connector instance, in the Instance information section, in the Friendly description field, type a unique name.
6. Click Save all.

The BlackBerry Administration Service updates the list of BlackBerry Attachment Connector instances automatically to use the names that you typed.
