The following connectivity is required:

1. The cDir application needs to be able to reach the BES/MDS Server by name or IP Address over HTTP.
2. The server(s) where BES and MDS are hosted need(s) to be able to access the web server where cDir is installed by Name over HTTP.
3. cDir needs to be able to send a SQL Ping* to the SQL Server (only applies to the Enterprise version for the secondary BES Database Servers).

Our recommendation is to host cDir on an internal server, not an external one.

[* a SQL Ping, as opposed to a normal ICMP Ping, will actually test if anything listens to port 1434 on the machine where the SQL Server is hosted].
