Q. I want to make changes to my schema and ensure I don't clash with third-party software. What should I use for the Object ID (OID) and schema prefix?

A. If you're making changes that are for use only in your own forest, the recommendation for the schema prefix is

<company abbreviation>-<product/project abbreviation>

For the OID, organizations can request a Private Enterprise Number from the Internet Assigned Numbers Authority. This number is free of charge and takes around 30 days to receive.
