Insert Windows 2003 SP2 disk

Situation: You're providing remote support and installing a new role in an old environment (Windows 2003) ... well, this is over the Internet, and you may have that SP2 ISO locally, getting someone to install it or transfer it or download it may be a bit longer than you need.

If you have the ISO, you can try to mount/share through your rdp client, or you can (for Windows 2003) wait for the app to ask for the files you need and upload them one at a time.

Hey, but the ISO has the thing as a single .exe! There's no folder structure!

It's true. But you can use, for instance, 7-Zip to extract  the .exe to a folder locally, then continue with the install remotely, where it will ask for the files it needs, then you can upload just those files in an accessible location. Sure, it's probably better to download and extract on the remote server. But if you only need a couple of MB of files and you've already got the SP2 locally, why not take a look at this as an option?
