Lync 2013 install on existing Network

Hi,

I want to setup Lync 2013.
My current Environment is

DC - Physical Server (AD/DNS/DHCP server)
Hyper V - Physical Server running 3 VMs.

I have set up another VM with 2012 R2 o/s where i would like to install Lync 2013.

I have read that the AD server needs AD-CS.
Can i install this without causing any issues to the current network?
The exchange has it's own certificate installed on the network pc's.

What issues will this cause? Will this interfere with my exchange?

Thanks

Hi mfmsupport,

I assume you are installing the Standard Edition (SE)?

The CA is required, however adding it to your domain will not impact anything until you start setting certificate policies.
Exchange runs off of its own certificate and will not be impacted in any way at all. You will however need your certificate thumbprint from exchange in configuring presence and IM for OWA.

The CA is required as lync will provide a certificate to any lync enabled user\device and the chain back to the server will need to be validated, so at a minimum domain computers will need to request a Cert from the CA.

But to confirm: adding AD CS and setting up the Lync certs will not impact the network or Exchange certificates.

Regards

Guy

You can install Lync server 2013 standard edition on one VM and you need to install ADCS on AD. it will not effect on your exchange server because Exchange Server use public certificate. It's only effect if you will configure Voice mail by integrate Lync with UM or Configure Lync on OWA, in this case you will need to sip address to exchange certificate and use this certificate on Lync.
For your information, To allow users using Lync from external, you will need another server for Lync Edge and Public Certificate for Lync.
