Situation; The client has a Windows 2012 R2 as Mitel phone server. After they start the server, they can’t ping or RDP into it.
Troubleshooting: 1. Ping server, it back with 169.x.x.x IP address.
2. The NIC 1 IP address should be 10.0..40. However, it was assigned 169.x.x.255 IP address which is auto-configured addresses.
3. We try to use DHCP to assign the IP address, but it doesn’t work. It still shows 169 IP address.
4. Then we reset IP address to 10.0.0.40, but it doesn’t take it and still show 169 address.
5. We fixed the problem by connecting the cable to NIC 2 and assign IP 10.0.0.40. I also remove the 10.0.0.40 from NIC.
