.NET Access is denied error

[Brent Burkart]

Has anyone seen the following error? My application was working fine and
this error just showed up this morning. Any help is appreciated?

Thanks John,

However this is not a domain controller. I am testing on 2000 and will be
production on Windows XP. Neither one will act as a domain controller.

Any other ideas?

Are you doing any XML Serialisation, and did you get the error when you
deployed??

I have seen that this fix also works on a machine that is not a domain
controller.
With SP4 a new privilege was introduced: Impersonate a Client After
Authentication
- The process identity for the aspnet_wp.exe worker process
(ASPNET
account by default) was lacking this privilege.

If this does not apply, what is your application doing at the time of the
error.
