Role change in log shipping

As a last step to implementing a log shipping role change...i..e making the
secondary the primary and the primary the secondary, do users change the
servernames so that apps that are referring the SQL server by host name
reflect the actual name .
We would like to implement some kind of disaster recovery using SQL 2000 log
shipping and wanted to know when we do role changes , what are the best ways
to allow the clients to still communicate to the now secondary server that
has been promoted to be the primary.I prefer the application being prepared for this. The app can for instance read the server name in a
configuration file somewhere and you quite simply change the config file to change roles.

Sure. I'd recommend you to make an alias on DNS server
wich will always lead to your production server. In this case
you'll need to change only this alias. (But if you use large
network you'll need to propagate modifications across all
DNS servers your clients use).
