Hi can anyone send a Info link How to merge two domains in a Single Forest

Thanks in Advance

No you cannot, you just can create a TRUST between the two domains, so they will be able to share infos.

To be honest, there's a way to do this:

But if you can simply use a trust, do it.

 

If not, you must RESTORE one domain:
