Waited a bit longer after I made this post - the top line is still showing the old domain info, but I'll just schedule a host restart to see if that fixes that part. I went back under the settings and it shows the correct info in there.
I tried adding the server to the domain and it spat out various incorrect domain or unable to find messages - I think I may have had the incorrect syntax, however my friend mentioned that he used the first one I had been trying (domain\name) and it worked fine. /shrug
