If On a domain controller, Aspnet_wp.exe fails to start because it cannot find a local account named "localmachinename\ASPNET". This is because on a domain controller, all user accounts are domain accounts and are not local machine accounts.

You can either 1) Create a weak account that has the correct permissions, and then configure the section of the Machine.config file to use that account, or 2) set the userName attribute to SYSTEM in the section of the Machine.config file, or 3) configure the section of the Machine.config file to use an administrator account.

"If ye love wealth better than liberty, the tranquility of servitude better than the animated contest of freedom, go home from us in peace. We ask not your counsel or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen."
~Samuel Adams
