Get the Active Directory functional levels/FSMO roles forest wide
Description
With the following script, it is possible in the same array to get useful Active Directory informations such as:
- domain names (DNS fqdn)
- domain functional level
- forest functional level
- fsmo roles
The powershell cmdlets used for this script are the get-adforest and get-addomain. The documentation for these cmdlets can be found here and here.
After that I use the select-object cmdlet (alias: select) to build my array.
