It’s used for two purposes right now and the first is probably the most important.

Step on, a small script runs on the local machine on logon that calls a larger script kept on servers. Corporate has created a read only location on each domain controller that is replicated specifically for this purpose. Right now because the script is only used at our locations (about 20 locations accessing about 11 domain controllers) I use an if/else statement to determine the site and then manually fill in the domain controller. Then I build the servers connect (example smb://somedomaincontroller/someshare) and open the larger script. By doing this I’m able to make changes to the main script for every computer in one shot. I want the closest domain controller (or even just the one the Mac is using right now) so that machines will attempt to connect to the local share if there is one rather than pulling the script over the WAN.

The second use is to fill in the LDAP server when configuring Entourage (I’d love to use Mail but I haven’t found ways to manage delegates, etc.).
