Public Enterprise Portal with Anonymous Access

Have any one tried public Enterprise Portal with anonymous access. I have followed the instructions given on the following link (excluding configuring SSL steps)

technet.microsoft.com/…/hh285823.aspx

The public EP website does work and open successfully without disabling “Windows Authentication” but When I disable “windows Authentication” in IIS as described in the document it start giving sharepoint error. Nothing is there in Event Log. Can anyone help me on this.

regards

Any one …
