Creating DNS SRV record for a Lync Installation
I always seem to forget how to do this, so I�ll put it here and I will never forget.
1. Open the DNS management console.
2. Make sure to right click the domain name (Fabrikam.com)
3. Select "Other New Records..."
4. Scroll down to, and select "Service Location (SRV)"
5. Click "Create Record..." and configure the SRV record like this.

Now the tool is updated, thanks Curtis Johnstone!
