Windows Active Directory Schema Versions

There are a couple ways to determine your Windows AD Schema Version: ADSIedit.msc and/or LDP.exe. In this article I use ADSIedit.msc.

Note: The sample domain used in this article is Servusinc.com. Substitute this domain with your own AD domain.

1. Open “ADSIEdit.msc “
2. Navigate to: “CN=Schema,CN=Configuration,DC=ServusInc,DC=com”
3. Right-click on “CN=Schema,CN=Configuration,DC=ServusInc,DC=com” and select properties.
4. Scroll down to “objectVersion” attribute.
5. The value of this attribute will tell you the schema version.
