In my VB6 app I am using msxml3.dll to talk to a
secure web service.

<code>
Dim req As New MSXML2.XMLHTTP
req.open "POST", "http://webservice.asmx", False
req.send strXML
</code>

A customer I have was working fine yesterday, but
now they get this error:

ERROR:12045-Client authorization not setup

Which has to with an invalid or missing root certificate.

On my test machine, I delete all the trusted root certificates
from IE6 and I can reproduce the error.

To fix it on WIN 98 I re-install IE6.

To fix it on XP I enable "Update root certificates" in
add/remove windows components.

The customer has 98, but re-installing IE6 does not
fix the problem.

What could be the problem?
