NOTE: I have attached the DHCPUTIL and all of the other required files with it, so you directly download them to your DHCP Server.
This is the shortest way to setup up Pin Authentication for Lync on the DHCP Server…
First Copy/Download all the DHCP Utilities content from Lync Front end server to DHCP server and run the following command line
Note: Make sure you run DHCP on Command line (CMD) as an administrator.
DHCPUtil.exe -SipServer YourFrontendFQDN.com –WebServer YourFrontendFQDN.com -RunConfigScript
On Lync Server make sure you run the following CMDLET on Lync powershell
set-CsRegistrarConfiguration -EnableDHCPServer $true
That’s it you should be all set after you ran this command line and you should be able to see the new DHCP options are showing in the DHCP server console.
To test the configuration you can run the same tool with a different parameter which will do the test for you, On a nother computer that’s not the “DHCP” open command prompt and run the following command line.
DHCPutil.exe -EmulateClient
Note: I’m attaching all the required files to this page below for download.
Troubleshooting:
If you run the command and you get the error below, then you might have a missing step
DHCPUtil.exe -SipServer YourFrontendFQDN.com –WebServer YourFrontendFQDN.com -RunConfigScript
C:\Users\admin\Desktop>DHCPUtil.exe -EmulateClient
Starting Discovery …
Result: Failure = -2147014848
Resolution:
On the Lync Server run the command
set-CsRegistrarConfiguration -EnableDHCPServer $true
Again on Lync server “Not DHCP” run the DHCPUtil.exe -EmulateClient to test the configuration.
