What do I enter when asked for FQDN (fully qualified domain name), for a PC that's not in a domain but in a WORKGROUP instead?

  • Depends on what's asking. What's asking? Oct 17 '12 at 19:31
  • @HopelessN00b Lync server installation. I am trying to install it on a standalone server that can't have domain controller, and I can't join a domain hosted on another server, because it runs 2003.

Workgroup computers don't have an FQDN unless you specifically configure them to have one. They have only a NetBIOS (single label) name.

Also, don't confuse the Primary DNS suffix with the DNS suffix search list as assigned by DHCP because they're two different things.


It would be PCNAME.

That's PCNAME plus a dot.


For Windows PCs you can check with:

ipconfig /all


Host Name . . . . . . . . . . . . : PCNAME

Primary Dns Suffix . . . . . . . : local

FQDN = Hostname + Primary DNS Suffix

So in this case: PCNAME.local

  • No, that's actually wrong. It's only PCNAME.local if your DNS suffix is local. Oct 17 '12 at 19:32
  • Obviousbly, when dns DNS suffix is empty, you'll get: PCNAME + null = PCNAME:)
