Thank you for your email.
i have done some testing and its not a VLAN problem as its a seperate NIC so I am not expecting the card to be VLAN aware.
I have 5 of these NIC’s all work on straight Windows 2003 server fine, its when the Windows 2003 Server is a virtual machine on Citrix XEN server.
While Citrix sees the USB NIC and I see it in the Windows 2003 Server VM and can set the IP, I can ping the interface from within the VM but Cirtix wont pass the traffic to the switch so i conclude that Citrix XEN Server is not compatible with the NIC which is shame as I like the NIC.
I looked in XEN server with xcsconsole and looked and it see’s it but unlike the Intel NIC It see’s it as “unknown”
I will buy a few Intel USB NIC’s if I can find them. I’ll keep these for other uses.
