“The domain controller did not respond within the required time; the domain
controller timeout may need to be increased” error message
Try one or more of the following:
INCREASE THE DOMAIN CONTROLLER TIMEOUT
If you used the device Kerberos setup file, then increase the number of seconds specified for the timeout entry in
the file. When you are done, reinstall the file on the printer.
If you used simple Kerberos setup, then:
1 Access the application configuration settings from the Embedded Web Server.
2 Under the Simple Kerberos Setup heading, increase the number of seconds specified in the Timeout field.
3 Click Apply.
MAKE SURE THE DOMAIN CONTROLLER IP ADDRESS OR HOST NAME IS CORRECT
If you used the device Kerberos setup file, then:
1 From the Embedded Web Server, click Settings or Configuration.
2 Click Security > Security Setup > Kerberos 5 > View File.
3 Make sure the domain controller IP address or host name specified in the configuration file is correct.
If you used simple Kerberos setup, then:
1 Access the application configuration settings from the Embedded Web Server.
2 Under the Simple Kerberos Setup heading, verify that the IP address or host name specified in the Domain
Controller field is correct.
3 Click Apply.
MAKE SURE THE DOMAIN CONTROLLER IS AVAILABLE
This error can occur if the domain controller is not available at the time a user is trying to authenticate to the printer.
You can resolve this by specifying multiple domain controllers. If a domain controller is not available, then the next
one listed will be tried. You can specify multiple domain controllers in the Kerberos configuration file or in the simple
Kerberos setup Domain Controller field. If you are using the Domain Controller field, then separate each value with
a comma.
MAKE SURE PORT 88 IS NOT BLOCKED BY A FIREWALL
Port 88 must be opened between the printer and the domain controller for authentication to work.
