“Lync gateway” VCS: Configure DNS and local hostname
Configure the DNS server details
The “Lync gateway” VCS(s) should be configured to use the same DNS server(s) as Lync Server.
On a machine running Lync Server:
1. From the Windows
Start
menu choose
Run
.
2. Type cmd into the Open field and click OK. A command window opens.
3. In the cmd.exe window type:
ipconfig /all
4. Note down the DNS server(s).
Note: a DNS server IP address of 127.0.0.1 means that Lync Server is using a DNS server on its own
hardware. Instead of entering 127.0.0.1 on the VCS, use the IP address of the Lync Server platform instead.
hardware. Instead of entering 127.0.0.1 on the VCS, use the IP address of the Lync Server platform instead.
On each “Lync gateway” VCS peer:
1. Go to
System > DNS
.
2. If the DNS server that Lync Server uses can provide all DNS lookups needed by VCS:
a. Set Default DNS Server Address 1 to the IP address of DNS server noted earlier.
b. If Lync Server has more than one DNS server defined, configure the additional default DNS server
b. If Lync Server has more than one DNS server defined, configure the additional default DNS server
fields (Address 2, Address 3 and so on) with the IP addresses of the additional servers.
3. If the VCS must use other DNS servers for normal calls and only the Lync DNS server for Lync access:
Configure the
Default DNS servers
with the servers which will be used for normal, non-Lync related
DNS operation and configure the
Per-domain DNS servers
section as follows:
Address 1
IP address of the DNS server used by Lync Server
Domain names
Domain shared with Lync
Address 2 … 5
Use these fields only if Lync Server uses more than one DNS server
Domain names 2
… 5
… 5
Use these fields only if Lync Server uses more than one DNS server; configure with the
domain shared with Lync
domain shared with Lync
4. Configure the next available Per-domain DNS server address to contain the IP address of the Lync
Front End Processor, and specify the Lync domain e.g. ciscotp.com as the associated Domain name.
(This is required in some network setups: Lync frequently embeds hostnames inside contact headers and
sometimes these can be unresolvable outside of the Windows domain.)

5. Click Save.
Ensure that Local hostname and DNS domain are configured
For each “Lync gateway” VCS peer, ensure that a unique Local host name is set up and that the DNS
Domain name is set up:
