I have a workgroup of 15 PC's and laptops that use static IP addresses. Two devices (1 PC, 1 tablet) lost their internet connection. The PC can ping the server & access shares but the server can't ping the PC. The tablet won't ping or access shares on the server neither wired or wireless. I have checked the IP addressing for the client, Subnet, Gateway & DNS. They are using the same scheme as other working clients (with different static IP addresses, of course). I am new to DNS tables and am at a loss how to diagnose two differing but similar problems.
