Virtual Connect, only sparse connectivity to server with NCU generated VLAN

On VC i have an uplink (not "shared uplink set") carrying tagged packets of several VLANs from Procurve 2810-48G.

Several ESX3.5 servers have vSwitches connected to this uplink, and the VLANs are running fine at least for console and VI clients.

I connected a Windows 2003 server to the uplink network, using Network Configuration Utility to configure an interface for VLAN1. Now I can ping to and from the server, but most other sorts of traffic fails - AD logon, DNS, SMB...

Just tried to add a shared uplink set and network for the Windows server, and this works much better.

What can be wrong in the NCU configuration?

Re: Virtual Connect, only sparse connectivity to server with NCU generated VLAN

make sure you are using NCU 8.80 at minimum as there are some VLAN fixes in 8.80.

Also, check for the NICs running TCP Offload Engine as there are some potential issues with that parameter. try disabling TCP Offload Engine and see if it resolves the issue.
