Hi All,
Have a Customer where I have deployed Lync 2013 Enterprise Edition on Windows 2008 R2, and the Lync 2013 client deployed to Windows 7 desktops.
Fresh install on 2013, no upgrade from Lync 2010 or anything else.
Getting the issue where the msRTCSIP-UserRoutingGroupID is wrong, and users can't sign in.
So I've queried AD and found the wrong value on user accounts, and replaced them with the right one and this fix works fine.
Problem is that the issue seems to re-occur intermittently on user accounts when they are enabled.
I'd like to know how this msRTCSIP-UserRoutingGroupID attribute is formed, as I've checked out the AD schema/configuration/naming context partitions, and can't see the hex value anywhere, or reference to how it is done from any searches on the internet.
Any help, as always, appreciated!
Cheers,
Hamish
