I have searched a bunch. One resolution was to enable Netbios..?

Any suggestions?

Have you disabled any services on the server or client side? How about firewalls? Check to make sure the SBS firewall isn't for some reason firewalling the interface your clients are using. Make sure the clients don't have the Windows firewall activated.
