As an administrator, coming across computer accounts which cannot be authenticated by the Domain Controller could be quite a common occurrence. More often than not, one of the reasons for this problem is the mismatch of the computer account and the secure channel passwords.
Computers that cannot connect to the domain also prevent users who use them from connecting to their domain and accessing the required resources. As this might impact the user productivity, you have to quickly and immediately reset those computer accounts.
The bulk reset computer feature makes allows you to reset the passwords of multiple computer accounts to the default initial value (%computername%$).
