Remove interface and add new interface again. Now give the static IP address.

Hello Experts,<br />
<br />
I have interesting situation after firewall migration on two of my virtual servers Win 2012 R2 exhibiting very weird behavior with default gateways.<br />
<br />
During migration I have two firewalls in the same network one with 192.168.1.254 (old) and 192.168.168.1.1 (new) So i just simply swaps default gateway on each node with static IP inside of the network &nbsp;from 192.168.1.254 (old) to 192.168.168.1.1 (new)<br />
<br />
Everything worked fine on most of the servers except two virtual servers located on totally different hosts. Default gateway 192.168.1.254 (old) would reappear resulting in two default gateways on same NIC. Every time I remove 192.168.1.254 (old) and just leave 192.168.168.1.1 (new) the old DG will comeback in just few hours.<br />
<br />
Did anyone see anything like that before?<br />
<br />
Thank you

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
