It is much more complex than it sounds. I have been pushing out new computers on the network and they are working fine, except they cannot be pinged and are unable to share services (printers). The only difference I have found between those and the computers on the network that CAN ping, etc. is the Security tab in found in DNS Manager. The working ones have an account that is the computers network name with a $ at the end. Those accounts DO NOT exist in the AD. I am stumped and are looking for help.

Hi, Have you checked the Firewall settings? You can disable Firewall temporarily to test. If still no improvement, lets test in Clean Boot. a. Click Start, type "msconfig", press Enter.b. Switch to Services tab, click Hide all Microsoft services, click Disable all. c. Switch to Startup tab, click Disable All. Click OK to restart. If the issue persists, on your DNS server, could you find A record of these new computers?
