Install ISPConfig on an already configured server?

[freedog96150]

I have a configured and operable Samba server on CentOS4. If I install ISPCONFIG, will the samba configuration get changed or left alone??

Here is the setup - This in an internal testing server. This server has no external access. I use Samba so that the developers can access directories from network places on the XP boxes. When they want to put a test site up with dreamweaver, I get called and have to create the directory structure,etc. That is why I am looking at ISPConfig. If I can safely install onto a production server, then that will allow me to turn control over creating/deleting test domains to the developers themselves.

Thanks for your help!
