In This article I will be explaining the Lync DNS requirements
One of the critical components for Lync to work is the DNS Entries. Lync uses two kind of DNS entries:
- A record
- SRV record
The DNS is usually deployed in a “Split-brain” deployment, this mean that the same zone as the external zone is deployed internally but with different IP-address than the public routable ones.

I’m sure a number of you had this problem too, a user complain that when he/she search the Lync client or phone address book for a user, they get no results.
First I would like to explain briefly how Lync Address Book is generated and synchronized.
- Changes done to the User account in the Active Directory are synched automatically with Lync every 60 sec.
- Those changes are written to the SQL back-end of your Lync Deployment.
- Every 24h (1:30AM server local time) Lync Address book server will start synchronization job that pull recent data stored in the SQL rtc database, and write them to the Address Book files.
- Lync Client or Lync Phone Edition download any updated address book files (.dabs & .lsabs) and update the “GALContact.db” saved locally, this process happen randomly by the Lync Client or Phone Edition.
