You accidentally delete the computer account for Server1 from the domain. You need to ensure that users can access the file shares on Server1 by using their domain user accounts. You must achieve this goal by using the minimum amount of administrative effort. What should you do? （）

B. On Server1, add the computer to a workgroup and then add the computer to the domain. Restart Server1.
C. From Active Directory Users and Computers, create a new computer account named Server1 in the domain. Restart Server1.
