Microsoft Exchange Server 2013 - Windows Server 2013 Standard - When logging in user hangs on - "Applying user settings" message

Question

Dear colleges,
Thanks in advance for viewing and suggesting!
Now for whatever reason it is the XCHG server is not responsive at all when launching ECP from the other computer on the domain. When logging in to the virtual box EXCH server is hosted on it hangs on the "Applying user settings" message for
an about an hour when finally logged in 4 or 5 XCHG services won't start... I don't remember exactly which ones - "...Mailbox Transport..." is one of them.
I read about the similar being an issue with Win 2008 R2 and EXCH server 2010, and followed the advice that I needed to add some entries to the registry - didn't help, disabling IP6 (which by the way makes no sense as XCHG needs one) - still didn't help.
Would you suggest to rebuild virtual server and reinstall EXCH all together as troubleshooting Windows issues may be lengthy?
Thanks!

Thanks folks! I think I have a clue what's going through don't know how fix it yet.
The problem is with DNS unable to resolve my main domain vwc.local. It makes some XCHG services to time out when starting. The error messages in the event log suggest about domain being unavailable
to contact.
When I tried resolving vwc.local with nslookup and ping it pinged THE OLD domain's IP address. When I setup server at home I specified this old ip address but changed it to a new one when I
moved box to the office. In the office everything worked very well - I introduced office's desktops to vwc.local, built a virtual box, introduced it the domain as well. Everything was good up until I started messing with XCHG. Now the domain is not resolvable
even though I made to be pinged to the new address by updating network adapter settings at the main server by selecting some checkboxes. But the vwc.local is still not available at VW where the XCHG is hosted on. When I open Server Manager/AD DS/AD DS
manager it gives me an error message about the DC being unavailable to contact.
How do I fix this domain mess now? Now I have 3 issues to deal with:
1. My remote desktop stopped working due to trial expiration even though I licensed server for 5 RDSCALs. This is a known issue with RDS and AD DS roles hosted on one physical box. Nobody seems
to know the step by step solution to the issue. I just got bunch of recommendations that I already followed. It looks like I need to call Microsoft and have them deal with their buggy software altogether.
2. DNS/domain issues described below. Something very weird. May I try re prepping the AD DS on the main server. I didn't try that may be I will.
3. XCHG not receiving messages from the outside.
:) Let's just focus on DNS/domain for a moment.
Thanks in advance!
