Authentication problem : response 401

[Tpk309]

Hello,

When I'm trying to use instant XML publishing on the company network, with internet explorer 8, I just get an error page.

With Firefox, I get an authentication dialog saying "Enter user name and password for http://'my-server-name'"

I've tried to enter there

- my network login/password

- my filemaker (admin) login/password) etc

And nothing work.

BUT :

If I just click on 'Cancel', I get another authentication dialog saying

"A user name and password are being requested by http://'my-server-name'. The site says: "'my-db-name'""

There, I enter my filemaker login, and I get the XML I want.

The problem I that I have no idea where the for authentication dialog does come from, and I'm trying to use fmDotNet but it is not able to connect to the DB, and I guess it's for the same reason that I received the firt authentication dialog.

Thank you if you can help.

Found, the problem was related to IIS (probabbly an old user that the admin had used with an old exchange server)
