A seemingly random group of my computers on my floor recently began refusing/not replying ping to their DNS Names or their IP Addresses. Several days ago it appeared to only affect a couple of machines. As systems are restarted more and more appear to begin refusing / not acknowledging the ping. This has also affected my ability to remote either by VNC or by Remote Desktop.
- These devices can see out to the internet with no issues.
- Devices vary between Windows 10 Pro and Windows 7 loads and different equipment.
- Some/Most of the identical setups are still responding to pings and allowing remote access
- Cold startups of device appear to be the trigger to make them stop responding, but not every time/machine.
- You cannot ping the device IP or DNS Name from anywhere on the network.
- You cannot ping from one affected device to another affected device
- YOU CAN ping any non-affected device on the network, all the way to the router and out to internet
- The Windows Firewalls on each device are turned off by a Group Policy
- It affects both Ethernet and Wireless connected
I have turned on the firewall and manually added a rule via "netsh" to allow ICMPv4 inbound. and turned back off. (No change) "netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=allow"
Any suggestions on trouble shooting would be helpful !!
