If you do a forum search for 1722 you will see this issue has popped up over the years, with no real solutions. I did a quick google search and didn't find much in the way of solutions, but many instances of this happening, even outside of kixtart.
One article I found that had a fix is below...
I found the problem. The RPC server is unavailable because the service couldn't function properly because it's dependancy (server service) couldn't start... I checked the dependencies through the server's properties and I looked through services and started those required dependancies to start the server service, once that started... Everything functioned properly. Sorry, didn't mean waste the thread. I just hope this thread will come handy to those who stumble upon it through google with a similar problem. xD
