Not in this case.

There are a few things that could come into effect. The best way to know
what is happening (at a connection level) is to quickly tcpdump trafic
from your AD to your virtualized Windows server, and see if it goes
through when authenticating to domain.
# tcpdump -ni <egress-interface> ether host 00:16:3e:00:00:13
If yes, check the date in the windows server. In virtualized
environments, clock skew can be important, and as AD has some Kerberos
thrown in (although I am not familiar with the implementation), too much
drift is likely to make the join fail.
