Sometime the domain controller it self give error when trying to logon “There are currently no logon servers available to service the logon request”, this can happen because multi-pull reasons, to get access you need to re-start the server in DSRM (Active Directory Restore Mode), this fix the ntsd.dit (Active Directory database):
Log on to DSRM
If you do not remember the the password :
o Reset the DSRM Administrator Password
- Click, Start, click Run, type ntdsutil, and then click OK.
- At the Ntdsutil command prompt, type set dsrm password.
- At the DSRM command prompt, type one of the following lines:
- To reset the password on the server on which you are working, type reset password on server null. The null variable assumes that the DSRM password is being reset on the local computer. Type the new password when you are prompted. Note that no characters appear while you type the password.
Then check the data base with ESENTUTL : https://itsimple.info/?p=772
Then restart the server in a normal state :
Start the System Configuration (msconfig) and navigate to Boot
Deselect ‘Safe boot’
Click on Apply
Restart the server and afterward you can logon to the domain controller and verify if the Domain Services are running
