In order to use Lync Phone Edition devices on your network you must configure DHCP options to support Lync Phone deployment. Lync 2013 has a nice little script that can configure a windows DHCP server with the correct options. This is located on the Lync Front End server in c:\program files\common files\microsoft lync server 2013 directory. The 2 files you need are
Copy these to your DHCP server.
To configure the DHCP server open Command Prompt and go to the directory where you copied these files. From there run the following command
dhcputil.exe -SipServer lyncpool.domain.com -WebServer lyncpool.domain.com -RunConfigScript
You may get an error message saying the MCVCR110.dll is missing. This is a C++ runtime dll. You can install the C++ runtime if you want but a quicker way is to copy the following files from a server that has this already installed (like the front end). You will need 2 dll files
Copy these files to c:\windows\system32 folder on your DHCP server and re-run the dhcputil command.
For convenience I have included the 2 DLL files in this post below
msvcp110 (PLEASE NOTE I HAVE HAD TO CHANGE THE EXTENSION TO .DOC TO UPLOAD DUE TO RESTRICTIONS. PLEASE RENAME TO .ZIP)
