I need some help

I downloaded and Installed Hyper-V r2 .

Install went fine and i was able to enable the remote management features and add VMs from my windows 7 Hyper-v MMC.

I was able to create and start Two VMS.. Neither of which had access to the LAN acces.

I created a Vlan (external) and hit apply.. Since then  i can no longer connect to Hyper-v through the MMC on my local windows 7 maching or anything.. .I have console access to the box, but i'm not sure why creating the vlan (external) killed my connection to the server or how to revert the changes

I can't figured it out and this is the second time I had to install Hyper-v r2 as the problem happened last time and i didn't realize it was the change to the v-lan settings..

If you set the External VLAN without "allow management operating system to share this network adaptor" then you will lost connectivity unless you have a second NIC to connect to.

I did select that button... But It turns out i have a flaky switch that is dropping connectivity to the management port (second nic).

Thanks for the link.
