Hi, Xinda,
Here I I got another scenarios. As mentioned, I had one guest Win2003 (say A instance) which can get onto internet with static IP, and while another Win2012R2 cannot. I tried to install another Win2003 guest ( say B instance) to coexist with A. However, the B instance cannot get onto internet with static IP either, even though I configure the networking settings of B instance exactly the same as A instance. I really can't figure out why.
Thanks,
Joey
