Error: 'is the Infrastructure Update Owner, but is deleted.'

Hi,

Would anyone be able to help us out please, we have an issue on one of our domain controllers at the moment:

Role Infrastructure Update Owner = CN=NTDS Settings\0ADEL:2eeb5301-6b1a-4ac8-a57e367363b389d6,CN=SERVER1,CN=Servers,CN=LE,CN=Sites,CN=Configuration,DC=holdings,DC=com

Warning: CN=NTDS Settings\0ADEL:2eeb5301-6b1a-4ac8-a57e367363b389d6,CN=SERVER1,CN=Servers,CN=LE,CN=Sites,CN=Configuration,DC=holdings,DC=com is the Infrastructure Update Owner, but is deleted.

I've seen these, but want to make sure i'm going in the right direction:
