"Using HP ProLiant Network Teaming Software with Microsoft® Windows® Server 2008 Hyper-V or with Microsoft® Windows® Server 2008 Hyper-V R2" HOWTO, 4th edition

NOTES
If you install the teaming software before installing HyperV, the
network adapters may stop passing traffic. To resolve this issue,
uninstall both the HP teaming software and Hyper-V and then
reboot the server. Reinstall Hyper-V and then the teaming software.
There is no known method of uninstalling HP ProLiant Teaming
software on machines running Windows Server 2008 Server Core.
We are developing a tool for removing the teaming software. It
will be available on the HP website in the future. We recommend
that you configure any machine that will run Server Core, Hyper-V,
and teaming during the initial installation using the order of
installation described above.
Uninstalling teaming software
1. In Windows, select Start > Control Panel.
2. Double-click on the Network Connections icon. The Network Connections window appears as
shown below.
3. Right-click any Local Area Connection icon and select Properties.
4. In the list of protocol and services, select HP Network Configuration Utility and click Uninstall.
5. After you uninstall the utility, the operating system typically asks if you want to reboot the server.
Click Yes.
