KB-8908: When pre-creating a computer, it fails with "constraint violation"

Authentication Service ,  

1 July,17 at 06:58 AM

Applies to:
All versions of DirectControl when pre-creating computers

Problem:
When attempting to pre-create a server, a popup message opens that says a 'constraint violation has occurred' 

Cause:
A servicePrincipalName conflict has occurred.

Resolution:
Run the following command for each server name to find the servicePrincipalNames that are conflicting so one can be changed as they must be unique for each machine: 
dsquery * forestroot -filter "(|(servicePrincipalName=afpserver/servername*)(servicePrincipalName=cifs/servername*)(servicePrincipalName=ftp/servername*)(servicePrincipalName=host/servername*)(servicePrincipalName=http/servername*)(servicePrincipalName=ipp/servername*)(servicePrincipalName=nfs/servername*))" -attr distinguishedName servicePrincipalName
