Why domain-joined server was assigned with "guest or public network" profile?

This is a newly-setup MS Windows 2012 R2 AD Domain. There are 2 DCs, both W2K12 R2. However, found that one of the DC and few other W2K12 R2 member servers (all are VMs) was assigned with "guest or public network" profile, instead of Domain network. On the network and connection center, it was shown with "unidentified network". Even logging on with a domain user (or admin), this seems like a local user account profile. for example, a domain user account logged on affected DC was given the user path of "c:\users\administrator folder. While the correct ones should be "c:\users\administrator.TS" folder (TS is the domain name). Btw, what's went wrong? What should I do to get them back to the right track?

I heard that may have to delay-start the NLA service? is that true?

Appreciate for your help, many thanks.
