Core Issue
During the Cisco CallManager installation on the subscriber, after the base OS installation, the Cisco CallManager installation stops responding with a Installing DC Directory message. However, the subscriber is able to ping the publisher's IP address.
Resolution
This issue can arise if the publisher's name is not resolved. Ensure that you do the installation by specifying the IP address of the publisher rather than the hostname. If the hostname is used, ensure that the name can be resolved either by a Domain Name System (DNS) server, or a mapping for the hostname to the IP address is available locally in the LMHOSTS file.
To learn more about LMHOSTS files and creating entries in them, refer to the Microsoft LMHOSTS File documentation.
