Seconded. I also suggest sharing how you mitigate the pain this can cause the developers who write apps that connect to the DB. (don't they all?)

I'd also mention the obvious warning that you shouldn't do this to a production server without considerable impact assessment and CYA/approval from management. Sure you can grep your filesystem for connection strings in sourcecode, but you'll start getting calls from users if your company allows Excel to connect to the DB directly. (you know workbooks multiply like rabbits, increasing the number of documents that would need to be updated)
