Similar thing happened here a few months ago. It turned out to be the machine
going to sleep. After we disabled the option to allow the NIC to be shut down
for power savings the problem went away. It drove us nuts for weeks.

It happens on all OS’s for me and it is random.
I can reboot a box 6 times and it comes up.
Then at 3:00 am in the morning it reboots and the nic shows the 169.x.x.x
address.
Disable and enable the nic and everything comes right back up.
We are using the VMX or E1000 drivers and still get the same random results.

We the same problem with our 2008 servers. There is a MS fix/patch that
sometimes fixes the nic. Else we just disable and reable the nic.
We use the vmx3net nic and vmtools are not always up-to-date. It is very hard
for us to get down time just to update vmtools.

What vNICs are you using? (E10000 or vmxnet3?) Tools up to date? vSwitch
settings? (Disabling MAC changes, promiscuous mode, etc?)

Hello Everyone,
I have an annoying problem that’s been vexing us for months now.
All our servers are virtualized with static IPs running on VMware hypervisors.
The servers that have connections to more than 1 ip sometimes drop their
connection.
Other machines connected to the same network don’t lose their connection so I
don’t think it’s the link between the hypervisor and the switch. It appears to
be a windows problem.
Anyone else have servers running Windows 2k12 R2 that are connected to multiple
networks that somehow lose connection randomly from time to time.
If we disable and reenable the NIC then they come back up but they really
shouldn’t go down at all.
Ideas?
