Hello, Does Microsoft support teaming for Domain controllers? ThanksTom

Teaming is not a Microsoft Windows function. I assume that you are referring to teaming provided by HP software/drivers. In any case, if you are familiar with teaming, the software will basically present the NICs that are teamed as one virtual NIC. Teaming provides different options for load balancing and failover. From my experience, I have not found much value in teaming DCs. The reason is that if you have multiple DCs and you loose network connectivity for one of them, you already have redundancy built into your design by having other DCs. While teaming works, you are adding extra complexity in your design and complexity always adds risk and reduces reliability. In addition, teaming requires additional NICs to be enabled, extra wiring, additional switch ports. For one DC, the cost is minimal, but it can add up if you have quite a bit of servers to team. Whether or not you decide to proceed with teaming should be based on a cost/benefit analysis. Guides and tutorials, visit ITGeared.com.

Thanks. So it appears though it is possible, stay away from it when it comes down to DC's? Right? I am doing teaming on 2008R2 for a lot of applications like sharepoint, scom, exchange, sql etc. but while configuring additional DC's I saw memory leak as well DNS seeing the active and standby NIC's as dynamically addressed.
