Server can't ping gateway

I have a network with about 60 hosts and suddenly one of my servers can't ping the default gateway or get to the internet. It can ping all other hosts on the network and no other device is having an issue getting to the gateway. The server in question is running Server 2012 R2 and has been working fine for months. No changes to the IP settings on the server have been done. It has a static IP and the configuration is correct. I can remote desktop to the server, but it cannnot ping my gateway or get to the internet.

I have a different subnet on my lan and if I configure for that subnet, it can get to the internet, but not on the subnet it has been living on for months.

Any ideas??
