Hi, see the nic card should itself support itself be dot1q enabled.If it is just go into the properties and confgure it for different vlans.but this is not the optimzed sol since broadcast effectting one vlan will affect the server.this server will recive all the brodcasts,multicasts and unknown packets.so It can be reduce the performance of server too.Its best you introduce some other layer 3 device for Vlan routing. Moreover Please search on cisco site so that you may clear before hand asking for doubts,I mean to say then you can focus on the problem more by that way. Cheers
