In my event log I see this error generating every minute (Event ID 6482):

I have been trying to resolve these for the last couple of days. But nothing helped.
Just to let you know, I tried adding/resetting the SPN from PowerShell as Administrator using setspn but it says "Insufficient Access Rights to perform this operation" although ideally it should since I am using the privileged account to run this script. Moreover I dont access to have Domain Controller so can not delegate the access rights either.
Please let me know how to resolve this as these 2 errors are filling up my event logs and might be causing the site to go down quite often.
