Windows 2008 R2 DL380 G5

[John333]

Hello,
I've a big problem,
I've installed windows 2008 R2 core edition. Then I used the cqniccmd to configure team on 2 nic. I enabled Hyper-V role on it, but when I try to configure the Virtual switch remotely I get the error:

Error Applying New Virtual Network Changes
Setup switch failed

Information is no longer available about this task because the object that monitors the

progress no longer exists. This may occour when many tasks are being processed.

I did a test on a single network without team configured and it worked fine, but if I select the new option in hyper-v R2 "Allow management operating system to share this network adapter" it fails again??!!!

Any clues?

I'm also searching for documention to 2008 r2 and hyper-v installations.
