Windows 2003, SP1. PPPoE SBC DSL Service. Server is configured as a AD,DHCP,DNS Server. In the DHCP Scope option, DNS Server is 192.168.10.10. The workstations can access the Internet but I am unable to ping any of computer on my small LAN. I look at DHCP leases and each one of them is in the same subnet...etc...No events in viewer...This must have started happenning after we got the DSL Service...cannot ping by name or IP..when I do ping 192.168.x.x it seems to go to administrator.xxx.com "public ip"...what is happening in my network.
