server 2008 with hyper v host died. Have to rebuild, it was domain controller

I had an issue because I was trying to run hyper-v 2008 r2 vms on a non r2 build.  I just reinstalled 2008 (this time rs) and need to recreate my domain.  I log into other computers on this domain.  How do I "replace" my old domain?  If I just use the same domain name and add the same users and passwords will everything work?

the server gave you a new profile becuase it is a new user, it has a different SID now. You can move the file over. Depending on what OS you have you could use moveuser.exe.

Is this your only domain controller?

If it is you will need to either restore a system state backup or re-create all your users and re-add all the other servers and computers to the new domain you create.

Yes, it is my only domain controller, and was my hyper-v host.  It is just one box running hyper-v and some vms.  The vms were shut down and I just installed a new os on the box.  I guess i really have no real reason to name the domain the same, or the computer the same.  Can I do that and just re-add users without any problems?  Should I rename them?

server was called Universe (had dc and hosted vms)
domain: development

Can I keep this computer as universe and keep my domain as development?

I do login to my desktop with a login from the old domain (development\jack).  If I recreate everything, can I still use this login and everything will work?

Would it be better to use other names?

Thanks again?  I am not really worried about losing all that much.  This isn't a big company, just me and some dev vms.

You can keep everytinhg the same name since that was the only DC. All your computers will need to be re-added to the new domain even though it is the same name.

Thanks.  I did that and most everything works.  I went to my desktop, removed it from the domain, restarted, re-added, then restarted.  When I login with my domain account "myaccount", I get a blank desktop that looks new.  If I go to c:\users, I now see myusername.mydomain and myusername.  the one with the domain is new.  So my desktop can now see the dc and allows me to login.  I can also browse to my servers files.  For some reason my desktop thinks my user is different.  Is there any way to tell it that they are the same, or move all user settings to the new account?  Is there a merge?  Would cut and paste work?
