This can happen for a number of reasons, but the main issue seems to be with DNS settings. However, if you have auto logon enabled using a domain account, simply wait. When the message occurs on the screen that “No logon servers available to service the logon request”, Windows will automatically try again after 2 minutes. I have had this issue, but it resolved itself after a 2 minute waiting period.
Of course this is irritating, so what to do if you are sure your DNS settings are correct? Well, try these two GPO settings:
1. Computer configuration -> Administrative templates -> System -> Logon -> “Always wait for the network at computer startup and logon”
2. Computer configuration -> Administrative templates -> System -> Group Policy -> “Startup policy processing wait time”
This value should be set to a value like 120 which is 2 minutes of waiting time.
Do the above, and your domain auto logon error should disappear.
