Adding a standby server

By rcs ·
I would like to add a standby server to an existing network to go online in case the main server goes down. The main server is set up as a domain controller and serves a database program and an email proxy program. There are 7 other win98 machines attached to the network. Does anyone know of any software to do this or any suggestions on how to set this up economically?

Adding a standby server

I've used Legato Systems Vinca/Stand-by server in several companies with great success. Check out the following link.

Admittedly most of my experience has been with the Netware versions, however, friends have said the NT version is quite robust as well.

Regards,

Ron King

If you are looking for all of your functionality to move to the new server in the event of an outage on the primary, Microsoft Cluster Server is a good option, and most MS BackOffice products are "cluster-aware" so they will fail-over correctly.

If you only need authentication services (and maybe F&P), consider a simple BDC and use dfs (distributed file system) from MS.

Check out "Double-Take" by NSI Software.
This is an excellent High Availability / Disaster Recovery product. You would need another NT machine, though. I don't think it works on w98. The really great thing about this is that your "standby" server doesn't have to just sit there waiting for another server to fail, so it can still be a very useful server doing other things. In addition to the failover scenario, Double-Take excels at a number of other very useful functions in data replication. I strongly suggest you check out http://www.nsisw.com

Good Luck!

You could add a backup domain controller. This would allow users to login if the PDC (Primary domain controller) goes down. You could have a folder that's replicated off the main server, so that users could access their programs.. but they would have to know to switch to another drive..

The better solution (but a little more expensive) would be to setup a cluster server (software by microsoft). This would have two servers, controlling one set of disk drives. If one server goes down, the other picks up. It also handles load balancing. If you have server1 and server2 joined in a cluster, everyone would access a made up server name called "cluster" (or whatever you wanted to call it). So either server would handle the request, pulling from the same set of disk drives.

It's not that difficult to setup, and works out really well.

Hope that helps.
