One Liner in PowerShell to provide the following information .
5.Is the Server a Global Catalog
First we will start by running a one liner to give us the domain controllers
If any of you are like me i want to see less, so below we will modify the Line to give us only the information we looking for.
Get-ADDomainController -Filter * | Select-Object Name,Domain,Forest,Ipv4Address,OperatingSystem,IsGlobalCatalog
Now we see what we want to see 🙂
Hope this is somewhat useful to someone.
