Adding MS SRV Records for Lync


I’m trying to use Lync with my domain but the information provided by Microsoft doesn’t seem to work when adding in the online portal:

SRV _sip _tls 443 1 100 1 Hour

It doesn’t seem to accept that line in the tool.



Huh, that’s a kind of odd format for the record. Try filling out our DNS form with…

Update, May 2012: Note that this post was written back in 2011; it looks as though the format has changed since then. To generalize a bit, here’s how to put together a SRV record of any type for DreamHost’s DNS panel. Replace all of the all-caps words, other than “SRV”, with the appropriate value from the Lync control panel (or whatever else):

Name: _SERVICE._PROTOCOL (the underscores are important)
Type: SRV

The “Name” and “TTL” aren’t needed. (The Name is just your domain name — it’s implied by the domain you’re editing DNS for — and an appropriate TTL is already applied to all records.)

Here’s an example. Note that your results may look a little different if Lync has changed their setup since I last updated this.

Name: _sipfederationtls._tcp Type: SRV Value: 100 1 5061
