Some or all identity references could not be translated.

Scenario:
While installing sharepoint 2010 , I got the following error

Error : An exception of the type System.Security.Principal.IdentityNotMapped was thrown. Additional exceptiomn information : Some or all identity references could not be translated.

Basically I got this error after removing the Active Directory Role from the server while running the configuration wizard.



Solution:
I dont think there is an easy way to get rid of this error. So In my opinion options are
1. Re-install the OS and then proceed.
2. Re-install sharepoint 2010.
