Win2003 ServerIssues with Port Channel?

[Sighclops]

Hello all. I have had 2 different Windows 2003 Servers with Teamed 1000MB NICs have trouble when connecting to a port channel on a 4507. The server is not pingable while connected to the port channel. Once I remove the 2 interfaces from the port channel, communication is back up. I do see that when looking at the mac-address table for one of the interfaces in the port channel it shows both the virtual MAC of the teamed NICs and the physical mac of the NIC. This seems to be an issue but does not happen with any of our Windows 2000 Servers. They only show the virtual MAC when looking at the table.

Any information on this issue is appreciated. It may be more of a Windows problem than Cisco but I will check both.

Hello,

which NICs do you have (brand) ? Not sure if this helps, but what if you configure port security on both ports of the 4507, allowing only the virtual MAC address ?

They are HP NC7781 Gigabit Server Adapters.

I can try statically assigning the virtual NIC, but that would not be the preferred solution.

Thanks,
