How to automate a server change across a network?

[Glenn Brensinger]

We have several hundred clients at various sites, and have to change
the incoming mail server at each location. Rather than go to every PC
and manually change, there has to be a way to automate this. Most are
using Outlook, but some are using Outlook Express.

Can someone offer some suggestions on a tool to:

1. Create a new server account
2. Copy the settings from the existing account to the new one
3. Change the login and put in a temporary password
4. Change the POP3 server

We can then do this in a network deployment rather than have everyone
change their own (these are computer illiterates.)

Thanks,

Glenn
