Still have this problem: SBS 2000 / XP Client Firewall client keeps needing to be refreshed. IPconfig shows the client is correctly connected to the server as well as being locatable in "Network." Dual Adapter setup: Company.com on the external (addressed from ISP) Company.local on the internal (from DHCP) Pinging produces the correct address from either .com or .local. NSlookup shows local. EL
