I have one particular PC with the NCF loaded on. The automatic updates has
stopped working. When I manually run it, I get the error message "the
requested header was not found". Anyone seen this before?

I do not have a problem with the firewall running. Everything seems to be
working well. I have checked the TIDS and found nothing on this. I have
other PCs that are updating just fine so I do not think it would be an
internet connection.

I have even uninstalled, deleted the client directory, and reinstalled.
This did not fix the issue on the workstation either.
