Our company is in the process of transferring over to Lync using the Polycom vvx410, 500 and cx3000 phones.
We use Microsoft DHCP and DHCP is enabled on the lync server as well.
At the moment users can login by manually entering user details and also by using BToE.
However, when trying to use the Pin Authentication, login fails. the cx3000 gets a web service is unavailable error as well.
I have otions 120, and 43 sub-options using the dhcputil config script. Our servers are virtually hosted by telstra and we have the different states going to different vlans.
The phones successfully get ip addresses and i have the provisioning server working for automatic updates.
The offices are configured so
perth = 192.168.11.1
melbourne = 192.168.3.2
sydney = 192.168.2.2
the lync server resides on 192.168.0.35
Unfortunatley i don't have access to a phone log thats up to date at the moment so i will post that when i can. At the moment i have wireshark traces on the phone when a pin auth is tried. file attatched.
If anyone could give any insight to why this is that would be fantastic.

The above post contains details how to troubleshoot DHCP issue regarding LYNC.
Looking at your attached Wireshark trace the ACK does not contain a valid Option 43 string and therefore the PIN authentication fails.
I suggest you work with Microsoft on setting up your environment correctly.
