Your on-premises network has two subnets with Windows servers. Server4's IP settings are: IPv4 Address 192.168.0.10, Subnet Mask 255.255.255.0, Default Gateway 192.168.0.1. From Server4 you can ping Server1 and Server2, but pinging Server3 times out. From Server2 you can ping Server1 and Server3. Which misconfigured setting on Server3 would cause the ping from Server4 to time out?

The subnet mask on Server3 is the most likely misconfiguration. Server4 (192.168.0.10/24) can ping Server1 and Server2, indicating its network configuration is correct. Server2 can ping Server1 and Server3, suggesting Server3 is online and reachable from within its local subnet. If Server4 cannot ping Server3, but Server2 can, it implies Server3 is on a different logical subnet than Server4, even if they appear to be on the same physical segment. A misconfigured subnet mask on Server3 would cause it to incorrectly identify its own network, preventing it from routing traffic back to Server4, which it would perceive as being on a different network. An incorrect default gateway would prevent Server3 from reaching any external networks, but Server2 can ping it, so this is less likely. An incorrect IP address would likely prevent Server2 from pinging it as well. An incorrect DNS server would affect name resolution, not direct IP-based pings.
