ASP Script Mapping was missing from the default website.
If the .asp extension is there, make sure it has GET, HEAD, POST, and DEBUG verbs entered.
If it is missing, Add the .ASP Extension Script Mapping with Executable path of c:\winnt\system32\inetsrv\asp.dll, and the following verbs (GET HEAD POST DEBUG)
After making this modification, the Agents were able to send Inventory to the NS without error.
