I would definitely try and see what happens.

Have a nice day

Thanks for your prompt response. 
On Windows 2k3 (32 bit) device name is shown as Intel(R) PRO/1000 MT Dual Port Network Connection, while on Windows 2k8(64 bit) device name is shown as Intel(R) PRO/1000 MT Dual Port Server Adapter.


In Advanced properties section for  Intel(R) PRO/1000 MT Dual Port Server Adapter device there is a property Priority & VLan and its value is Priority & VLan Enabled.


Do you think should I change it to some other value?


Thanks,
Pushkar

  Intel have many different Ethernet adapters:

         http://download.intel.com/network/connectivity/products/prodbrf/252454.pdf

  so, even though both the boxes might have Intel Ethernet adapters, they might be *different* Ethernet adapters (for example, a desktop adapter on the 32-bit machine and a server adapter on the 64-bit machine), and the adapters and their drivers might treat VLAN-encapsulated packets differently.

  What precise types of Intel Ethernet adapters do you have on the two machines?

  ...or it could be an issue with the Ethernet adapter on the server machine, or its driver.
