Ghost Cast Server 11.5 Issues?

I updated my computers and when i did this I took on computer of the network and disjoined it from the domain and renamed it ghostcopy.  

 

I then proceded to create a new image of this system all went well with the new image.

 

I then had 3 computers that I had to image with this image they are already off the network so I just hooked one up and pushed the new image to the machine well it worked except for 2 things 

 

1. I cant change the name of the computer from ghostcopy to the name I want it to be to put back on the network how do i fix this?

 

2nd. The system settings change popup keeps coming up ??? How do i fix this?

 

Thanks in advance
