Super bizarre.  Not working…even with the revised record syntax.  I’m going to 
scour more online…

When I run the Lync test, it comes back clean.  So peculiar.  I also might try 
a few machine reboots.  Never hurts and some of these haven’t been rebooted for 
a bit.

More as the time unfolds.

I have an SRV record with them for Exchange Auto Discover, which may not help 
you much. I set it up a long time ago, but it works.

When you do a lookup on the SRV record outside of the domain, you at least can 
resolve the name, right? Are the clients inside the domain using DNS servers 
that are different than what is public? I’m not clear on that.

My settings are essentially the same as yours except that for some reason my 
TTL is 1440 and both weight and priority are 0, but I don’t think that would 
matter.

Subject: [NTSysADM] DynDNS & Skype for Business?

Has anyone successfully set up SRV records in DynDNS for Skype for Business?  
Every other DNS record is working correctly for me right now EXCEPT the SRV 
record for Skype for Business.  All the Google-fu-ing I’ve done has lead me to 
do the following:

The black lines are to hide my client’s domain.  I have a ticket in with DynDNS 
as well.  The weird part about all of this?  I can sign a client in and the 
presence is noted (green, red, yellow, etc.) to the clients inside the domain, 
however clients outside the domain cannot see the presence.
Super confused…wondering if anyone can help!
Thanks.
