2 New Virtual Servers can't join domain

I created 2 new Win2k8 virtual servers and cannot join them to the domain.  They are in a different subnet than the dc's, but I've joined other servers to the domain from this subnet before without issue.  When trying to join, I get the "an active directory domain controller for the domain cannot be found".  The dns records for these 2 servers appear in DNS on both dc's.  all other servers in the domain & the 2 dc's can ping these 2 servers.  

Any ideas?

I used FQDN and got an error, but the server was able to join the domain anyway.  So that was my solution.  Thanks for all the suggestions.

This sounds like it may be an configuration issue or DNS issue.
are you able to ping the FQDN of your domain from these VMs?
Also, when you attempt to join the domain, are you inputting the NetBIOS name of the domain? or its FQDN?

Have you verified your ipconfig /all ? What are the primary and secondary DNS servers? are they those of the domain controllers?

Are you pointing the DNS entries in your new servers to the correct DNS addresses?  Is the subnet fully routed or is there a firewall inbetween?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I can ping  the dc's by FQDN.  When I attempt to join, I am putting in the Netbios name, but also tried with the FQDN and neither works.  Ipconfig / all is exactly as the other servers on this subnet.  Primary & Secondary DNS servers are correct.  Tks.

Sorry, I think I may have misspoke, what I meant is, are you able to ping your domain's FQDN, not the DC...  as in ... ping internal.example.com ?

I realize your DNS is set static, but have you run (elevated) ipconfig /flushdns?
Is the gateway correct? If using vmware, have you restricted the address range of your vswitch? Have you confirmed settings correct on the virtual side? Is the time correct on the VM's?
