default gateway cannot be set
Hi,
We have a windows server 2008 virtual machine.
After applying updates we couldn't set the default gateway.
The default gateway in the tcp/ip 4 properties of the network connection is empty. When we enter the default gateway and we press ok and close the properties of the network connection, then go back, the default gateway is gone again. If we do ipconfig in a command prompt, it doesn't show any ip address nor the default gateway.
This problem is not the same as the known problem of the default gateway disappearing after a reboot. We don't reboot the server.
Any help is welcome.
Regards,

I think there is IP address conflict in network, hence system is unable to apply IP configurations
You can try with different ip address for confirmation

Hello,
No it's not a p2v machine. It always has been a virtual machine. And it also always worked this way without any problems. Until yesterday.
There are no hidden devices.
There is no ip conflict. There are 4 machines in that virtual network and all have a different ip.

is the W2K8 server a member of any existing AD domain?

The problem was symantec security. I'v uninstalled it and everything went back to normal.
have you checked hidden devices, especially any network interface?
