PowerShell Script – Generate DFS-R Health Reports and Email Them

Sure there are a few DFS-R scripts out there to choose from in various languages like batch, vbscript, and even PowerShell to name a few, but I decided to write one to fit my own personal needs at the time.

I created this so that it could be ran as a scheduled task each morning. Basically the script just lets you set an array of different replication groups to run the Health Report on, attaches them all to a single email, and then shoots that email off via an SSL connection through an Exchange server in this particular case.
