Hi,

I got 2 webservers running windows 2003 web edition
Im gonna use them in a load balancing system

This means when the 1th webserver goes down, the second down takes over his
IP adress, and with that all traffic

This is working perfect, the only problem i got is the synchozing of the
files

I understood that can be worked out by dfs (distributed file system)

But since i got the web edition, i can replicate with that, it needs a
domain for that

How can i still use dfs to synchronize files between the webservers, so both
got a updated version of the websites
or is it better to work with scripts that copy files all the time

Thanks for replying,

It's better with clustering, which can't be done on the web edition
either. The most common solution is a scheduled replication using
Robocopy or similar, or a replication at the time the files are
transferred from the development server to the production servers.

Yeah but the problem is that the files need to be real time synchronized,
since nlb is acting as a load balancer

I think the best solution is to have a fileserver behind those 2 webservers
where the webservers get their files from

Since this will be my single point of failure, im thinking to use linux as
fileserver

I use two servers as well. But I don't get complex with load
balancing. I image the hd from the first server to the backup server
(bus) and start that way. Then I use peersync mirroring software to
mirror the web, ftp and other important files to the bus. I export a
few registry entries to send to the bus as well like the odbc and
imail (mail server entries) and I import these into the bus.

I also use a program that sets up IP profiles on the bus so I can set
the IPs in the bux in the event of a failure. This configuration has
worked for me for 5 years.

For some reason I don't trust (maybe I just don't know how to use load
balancing) load balancing it all seems so complex - but then again it
may just be my simple nature. Wink

Anyway, just a little more info for you to ponder.

MS has a tool available for everyone to uses to deploy to NLB cluster or from dev >> Stager >> Live cluster. Suggest that you have a look at this.

Application Centre 2000

Fanatasic tool, also provides health monitoring!!!
Have fun
