Some users can’t connect anonymous to sherpoint 2003

Hello everyone,

I’ve recently installed Sharepoint Services on a Win 2003Svr Std Ed. I’ve configured the IIS and also the sharepoint site to allow anonymous connection.
Everything works fine for the users that have installed Win XP Prof.
The problem is that for users with Win Home are asked for username and password.

Can you please help me?

I use a workgroup for the network not a Domain.

Thanks.
