My Inspiron 15 3567 won't accept my login password.

Earlier today while I was trying to fix the DNS server, I removed my Administrator permissions by mistake. Now it won't let me log in. I have my home group password and service tag ID number. Also I registered it with DELL for warranty reasons. Anyone have any suggestions how to login or even reset it?
