DLNA problem after cloning OS

So, here's how I managed to end up in my current situation...

1. Built two identical media center PC's
2. Installed and configured Windows on one of them.
3. Cloned the hard disk in the configured system to the blank system.
4. Changed the product key on the cloned system so it's unique.
5. Changed the network names of both system so they're unique.
6. Changed the media library name on both systems so they're unique.

Windows Media Player has a built-in DLNA client and server, and is configured to auto-start on both systems so that other devices on the network can push media to them at will.

As long as only one of the two systems is on the network, it works as expected. My other devices can find the media center PC and push media to it. Its media library shows up in the "Network" section of Windows Explorer.

If I attach both to the network, something goes haywire. My other DLNA enabled devices sporadically find one or the other (or neither) media center PC's. If I look at the "Network" section of Explorer, I can see their individual media libraries appearing and disappearing over and over.


The two DLNA servers on the two machines appear to be fighting, knocking each other off the network again and again. I obviously missed something when attempting to make the two machines unique... any ideas guys?
 
You probably should of sysprepped the second machine. You can still do it now though. You will have to redo the initial setup part and reinstall any drivers and make software setting tweaks you made. Software should remain installed.

From an elevated command prompt

sysprep /oobe /generalize /reboot

(or /shutdown if you are going to clone the drive).

Doing this will reset the systems SID, making it a truly unique Windows. I'm not saying this will fix your problem though, it just makes Windows unique even if cloned.
 
You might (might!) be able to fix it by uninstalling then reinstalling the media player/media center windows components through programs and features. I checked the registry on my PC, and there's definitely some unique IDs under the Windows Media Player NSS keys. If you're lucky, they might get regenerated by just reinstalling those features.

Otherwise, like mentioned above, I'd imagine a sysprep would take care of it as well.
