Windows 10: lost my admin rights

I accidently deleted my admin accounts and dont have any access to my admin account.I only got my standard user account. I can,t recover/reset my pc. Since i dont have access of my admin account, i cant access the bitlocker key due to which i am not able to enter to safe mode too

admin rights keep disappearing!?!!

Hi guys,

I am actually having a problem at work that our IT department hasn't been able to figure out. I am supposed to be a member of the admin group. We are on a domain. The problem is that everytime I reboot the computer I loose my admin rights(no longer in the administrator group) and just become a normal user again. I have tried googling this and didn't get to many results.
I believe IT is just giving me local admin rights, not admin rights for the whole domain.

Any suggestions?

EDIT: It is on Windows XP Pro.
