On IIS The server xyzcompany.com at xyzcompany.com requires a username and password.
Warning: This server is requesting that your username and password be sent in an insecure manner (basic authentication without a secure connection).
I keep getting the above error (only on workstations on the internal network/accessing it on the internet works perfectly fine) from our IIS server. The settings in the authentication methods under directory security are Enable Anonymous access (Checked) - UNder authentication access (non is checked)
