Methods to remotely change virtual IP of server

Question

I'm intending to use virtual IP for my failover implementation.

Setup:

**Server A (192.168.0.1) ** - takes virtual IP of 192.168.0.10 by default
**Server B (192.168.0.2) ** - takes virtual ip of 192.168.0.10 when server A is down

I'm using Windows machines and my current method is to run a script on another machine to check if server a has failed, and when it fail, the script will telnet into server B to add the virtual IP.

I'm wondering if there is an alternative solution to using telnet to change to virtual IP. I want to ensure that the failover is automatic the option of getting a network administrator to add the virtual IP is out of question.

In orde to use a virtual IP you need to build a cluster. You didn't specify an OS version so you'll have to look up how to create one. Clustering has been supported since NT 4.0

I'm using a Win 7 Home Premium and Win 7 Professional in the cluster. Will there be any compatibility issues or since they are not "server" OSes. – tommi Mar 17 '12 at 02:57
@csl, are you *serious* ?!? – Massimo Mar 17 '12 at 03:32
You need to use a server OS. – Jim B Mar 17 '12 at 11:38

This is flawed in so many ways... please have a look at Failover Clustering and Network Load Balancing.

can you tell me more about the flaws? – tommi Mar 17 '12 at 02:56
You're trying to build your own homemade and totally unsupported clustering solution while the system provides you at least two ways to do it... – Massimo Mar 17 '12 at 03:31
