I'm looking for suggestions on how to connect our on-premises applications and data to Entra, but we want to do this without upgrading from Windows Server 2003 or using any cloud services. My company has about 100 employees, and we've been using our current setup for a long time, so any insights on how to make this transition would be greatly appreciated.

I get it, some companies stick with legacy systems for a while. If you want to keep things running on your 2003 server, you can't directly stream data to Entra, so it looks like you'll have to export your identities into a CSV and then use PowerShell to import those into Entra. That could be a bit of a hassle, but that's how you'd do it. Just make sure to check if there are any third-party tools that can help, too!
Honestly, connecting something as outdated as Windows Server 2003 to Entra can be tricky. Entra is primarily a cloud service, so you might run into several obstacles since 2003 isn't supported or secure anymore. Your best bet might be to start fresh with a new setup and export your users from the old server, then import them into Entra. It might seem daunting, but it's probably the safest route! Good luck!
C'mon, using 2003 in 2025? That's just asking for trouble. I can't believe some companies really think they can avoid cloud solutions. The security risks are huge! I'd highly recommend that you convince your boss to reconsider the upgrade for the sake of data security and efficiency. It's about time to future-proof your infrastructure!
