As an IT consultant I often visit new customers and it is always good practice to just double check which DC’s are available in the organization, which sites they belong etc.
To make it easy for myself I created a script that will get the:
- DC’s in the domain
- Uptime (in Hrs.)
- Site the DC belongs to
- IP address
- OS Version
- GlobalCatalog
- if the DC is a read-only DC
- Who carries which FSMO role
The below script will get this information and display it in your powershell session. You could customize the script to get more information are have the results emailed to yourself.
