SYMPTOMS

When you run the Active Directory Installation Wizard (DCPromo.exe), you receive the following error message:

RPC Server is too busy

Additionally, information similar to the following may appear in the DCPromo log file (Dcpromo.log):

07/11 12:43:42 [INFO] DsRolepInstallDs returned 1723

CAUSE

This issue may occur if the time setting on the server that is being promoted to domain controller is not the same as (or close to) the time setting on the domain controller that is providing the Active Directory information.

The Kerberos protocol requires that these servers have time settings that are within 5 minutes of each other.

RESOLUTION

Configure the time on your servers so that the server that is being promoted to domain controller has a time setting that is the same as (or within 5 minutes of) the time setting on the domain controller that is providing the Active Directory information.
