fault tolerant IIS ?

[Snow-Munki]

Hi,

I'm hosting a single file on IIS which all our users need. As it is quite important I need to make it fault tolerant.

Therefore I installed IIS on a second server and hosted the same file. Next from DNS I created a new entry twice pointing to both servers, using round robin.

However as a quick test, I picked the new entry from two different PC's and they pinged both servers, so that part works. However when I disabled the nic or switched off one of the servers, the ping would just time out. It did not try and look for the other server. I flushed DNS but still no luck.

Any ideas ?

Thanks,

Would you not need to set up NLB for this?

i think you will need something more than DNS to handle this

and what kind of faults do you want to protect against - network level faults, application (IIS) level faults?

hmm... been looking around and NLB maybe better. Just need to ensure the file is available at all times.

So if the server crashes, IIS fails etc it will know to use the other server.Obviously I can do this manually when users call up and complain but rather have it automated.

Thats basically what NLB does yes.

If you wanted you could use DFS to replicate the files across the 2 servers.
