Do you have issues with security on a fresh windows server when trying to access http(s)://serverroot = IIS

Admin access with admin accounts works, since they will default be in group:

Check Local Security policy->User Rights Assignment->Allow log on locally

Check Local Security policy->User Rights Assignment->Deny log on locally

Domain account no admin access does not default work if GPO has been set high:

Check Local Security policy->User Rights Assignment->Access this computer from network

Check Local Security policy->User Rights Assignment->Deny access this computer from network
