Hyper-V VM Windows Server 2003 R2 SP2 Network Problems

Hi Guys,

I am trying to setup a new VM in my lab (I am using windows 8.1 in my host)  with Windows Server 2003 R2 SP2. I already installed the integration services in that VM, the network adapter is ok (Hyper-V network adapter). Well, everything it seems to be ok, but my W2K3 Machine keeps getting 169.xxx ip. My host is wireless , the virtual switch is ok, since I have other 4 VM (W2K8, W2K8R2, W2012, W2012R2) working fine with that switch and having access to the internet, just this VM with W2K3 is not working. 

Do you guys can help ?

Thanks
