I am attempting to configure an Active Directory domain
account that will be used for the ASP.NET worker process
instead of local MACHINE or SYSTEM. I have followed all
of the MSDN articles for creating the user, setting all
of the required ACL's on various folders, setting the
local security policy attributes, etc.

I have modified my Machine.Config's <processModel>
section to include the new user credentials such as:
userName="MyActiveDirectoryDomain\MyUser"
password="MyPassword"

However, when I hit my site...the .NET runtime throws
a "Configuration Error" and indicates that an error
occurred while parsing EntityName on the <processModel>
line. It appears that the .NET runtime can't even parse
the config file correctly with the Domain\User syntax.
At least a rights issue would have resulted in an invalid
username/password error or does not have required rights,
etc. It doesn't even get that far...

I have combed through every white paper, web article,
etc. and can't seem to find anything related to this
specific error or how to solve it...

Thanks,
Mike
