subnet question

We are trying to implement Windows 2000 Network Load Balancing, however one of it's requirements states that all hosts that participate must be on the same subnet. MS also requires that these PC must be on a layer 2 switch. Their IPs are x.x.2.10 and x.x.1.10 They are on 2 different cards on the Catalyst 4000 switch. At first glance the answer is no, they are not on the same subnet, but I'm not too sure. Also is possible to create a VLAN using 2 ports on different cards on the switch? Is it possible to put those 2 PCs in the same VLAN without moving one of them to a different port and without changing IP addresses? Big thanks in advance.

Re: subnet question

It is possible to have ports on different cards (or on different switches, for all it could matter) belong to a common VLAN. Additionally to belong to the same subnet (should this not be the case at the moment) with the addressing you gave in the post, you need to make sure the netmask is such as those 2 address belong to same network. for example 255.255.0.0 (or if that is too big, you might try 255.255.252.0, which is btw the least you can use to achieve your purpose).
