We have comcast business class internet with 5 static IPs. 4 out of 5 of them are assigned to a server that sits right behind the smc. The smc has DHCP disabled so it should be in pass through mode.
Everything was working fine this morning, but tonight I tried to RDP into the server... no connection. so I tried a ping... No reply. I went and pinged all four of the ips. (first three bytes redacted)
- 0.0.0.130 --> Ping fails
- 0.0.0.131 --> Ping succeeds
- 0.0.0.132 --> Ping fails
- 0.0.0.133 --> Ping succeeds
its very strange. again, these were working in the morning, but now they are like this.
When I restart my computer, but before I login and ping it again, all succeed. As soon as I RDP in, the .131 and .132 both fail.
Im sure its not my end. I have a website sitting on the .132 and my phone and http://www.downforeveryoneorjustme.com/ says that the site is also down.
All statics are on the same nic and all configured the same way.
looks like the failed pings are not from RDP starting. While the machine is finishing up its boot it can be pinged on all of its ips, then they drop out.
I cannot find anything in the Event Viewer around the time the ping drops out
Server is running Windows Server 2012
