Hi,

I setup Server 2012 with RDS virtual machine based. I created a VM image and let RDS duplicate the image 10 times. I assigned the VM's to specific users. When the users login, they go to the server instead of there VM. Any idea what I might have wrong?

Hi,

According to your post, I can understand you have setup Server 2012 with RDS virtual machine based and found issue with user login to VM.

In accordance to this, I suggest you to cross check again with below link:

Virtual Desktop Collections available in 2 types:
1) Personal
2) Pooled
Among this 2 types, which type you have setup.

As per my thinking the issue related to UPD (User Profile Disk) settings.
You can refer to below link for UPD setting:
