I learned something cool when I was in the USA last time. When you have an Exchange 2007 system connected to Exchange 2003, you get the following Exchange 2007 Administrative Group and the Exchange Routing Group to connect the systems together. You are also warned not to change the name of the Exchange Administrative Group (FYDIBOHF23SPDLT) or the Exchange Routing Group (DWBGZMFD01QNBJR)
What I didn t know is that these random characters are in fact codes.
A simple letter substitution reveals that FYDIBOHF23SPDLT is in fact EXCHANGE12ROCKS and that DWBGZMFD01QNBJR is in fact EXCHANGE12ROCKS
Cool huh right in front of you and you didn t even know it!
