Introduction

This article describes the Microsoft Support Policy for Network Adapter Teaming when used in conjunction with Hyper-V.

Network Adapter Teaming is a 3rd party Technology that provides fault tolerance for multiple Network Adapters.

Summary

Since Network Adapter Teaming is only provided by Hardware Vendors, Microsoft does not provide any support for this technology thru Microsoft Product Support Services. As a result, Microsoft may ask that you temporarily disable or remove Network Adapter Teaming software when troubleshooting issues where the teaming software is suspect.

If the problem is resolved by the removal of Network Adapter Teaming software, then further assistance must be obtained thru the Hardware Vendor.
