Q. When installing Exchange Server 2007 into an Exchange Server 2003 or Exchange 2000 Server environment, do the names of the automatically created routing group connector group and administrative group always have those same random letters and numbers?

A. Installing Exchange 2007 into an existing Exchange 2003 or Exchange 2000 organization automatically creates an administrative group named CN=Exchange Administrative Group (FYDIBOHF23SPDLT), and a routing group named CN=Exchange Routing Group (DWBGZMFD01QNBJR).

Those letters and numbers are not as random as you think, and they are always the same. A Caeser cipher was applied to EXCHANGE12ROCKS to create the two seemingly random group names. The letters and numbers in the administrative group name are all one letter or number before the letters and numbers of EXCHANGE12ROCKS. The letters and numbers in the routing group name are all one letter and number after the letters and numbers in EXCHANGE12ROCKS.
