Event ID 1056


KB ID 0000121 Dtd 10/11/09


The DHCP service has detected that it is running on a DC and has no credentials configured for use with Dynamic DNS registrations initiated by the

DHCP service. This is not a recommended security configuration. Credentials for Dynamic DNS registrations may be configured using the command line

“netsh dhcp server set dnscredentials” or via the DHCP Administrative tool.


You need to reset the credentials that DHCP uses.

1. Start > run > dhcpmgmt.msc {enter}

2. Right Click the Server > Properties

3. Advanced Tab > Credentials > Enter the domain admin credentials > OK

4. Start > Run > Services.msc > DHCP Server > Right CLick > Restart

5. Start > Run > eventwvr.msc > Make sure that there is not another 1056 Error.
