Global server IDs on Network load balanced servers

Greetings,

I have been tasked with setting up three Windows 2003 servers, network load balanced together to service 1 website (using IIS 6).  Does each individual server require a seperate Global Server ID or will one suffice?

Any quick pointers or advice on network load balancing?

Thank you

The three machines need different ID's otherwise the servers should be almost exact copies of each other.

Load balancing - it will depends what your budget is, but I would say speak to a CISCO reseller and ask about a Local Director

THe reason I would go with hardware is
1. You offload the burden of the load balancign from the servers which should be serving content
2. There is an extra layer of address translation which makes hacking a little harder
3. Who would you rather rely on in a critical environemnt CISCO or Microsoft ?

If you go with an MS solution you need to look at their "clustering services" strictly speaking clustering is not what you need for web servers you do need load balancing, however it looks like the marketing people got too involved in naming things!

Small note : You can get away with the cheaper web edition of 2k3 server in which ever scenario you choose
