While deploying the SharePoint 2013 preview on a VM, I ran into a small problem. The install itself ran great, but I kept getting an error while running the SharePoint 2013 Products Configuration Wizard. Essentially the error was indicating that a component didn’t support running under the NetworkService account in a Workgroup environment.
A bit of searching and I found that a couple of other people have already run into this and solved it. Here is the best explanation I found. The error is for the AppFabric caching component. Once I followed the steps Tom lays out in his workaround, I was able to re-run the Config Wizard and everything is back on track.
