Before trying any of these suggestions can I recommend checking that the network applications will run before hand. Many customers have no idea what NetBIOS is and have heard it's a bad thing.

New ones, Like Symantec's products, let you set "personalities" (standard configurations) up in advance and push updates to policy to the clients from a central console. Cheers!

Your client may have to replace some hardware to get this feature, but it's available if they want it badly enough. David Gillett

The most important thing is to disable it internally ( inside the LAN) Any suggestions??? Taking in consideration that there is DHCP server for the clients ( If it can contribute in the Solution) Best Regards, Kareem Mahgoub
