Identifying what domain controllers are not global catalogs

Dear everyone,

I hope you are all well and can assist.

I would like to build a query at does the following:

1) Gets a list of all domain controllers
2) For each domain controller, determine if it is a global catalog or not
3) Write to a file the names of the domain controllers that are not global catalogs

Any help greatly appreciated.

adfind is a great freeware tool by Joe Richards

He has shortcuts that can really make this easy

adfind -sc gclist  
This dumps all GCs

adfind -sc !gclist
This dumps all non-GCs

If you have Visio you can also use the AD topology diagrammer and it will draw your DCs

Mike, with the returned domain controllers that are not GCs, is there a way to loop through that list and add the GC role to them?

You would have to pipe it into admod.  I'd have to test it out.  Don't want to give you code that doesn't work.

How many do you have?

Thanks

use powershell:
Get-ADDomainController -Discover -Service "GlobalCatalog" > output.txt

to get the GC DC's then run script again without -service switch to get All the DC's can save it as getDC.ps1and then call that with your query
