Problem

A few weeks ago my boss asked me to take a look at Microsoft Lync. Because he was interested in the Lync Client (formally Microsoft Communicator) for instant messaging.

Decent info is a bit thin on the net, and I don’t have the patience to read stupidly long PDF files. So to redress the balance I thought I would publish my findings below.

Solution

Note: The following procedure is carried out on Server 2008 R2 with Windows 7 Clients, on my VMware test network.

Walkthrough

I know a lot of people don’t like watching videos so heres my notes:

Pre-Requisites

1. Download and install, Microsoft Silverlight. (link)

2. IIS (Roles > Add Roles > Web Server IIS) > Next.

Also add:

i. ASP.NET

Next > Install > Finish.

3. RSAT Tools (Features > Add Features > Remote Server Administrative Tools > AD DS and LDS Tools) > Next > Install > Close > Select Yes to Reboot > Post Reboot Installation will continue > Close.

4. Have a Certification authority set up in your domain. OR a certificate ready for the Lync Server to import.

14. Select features (Everything except PSTN, because I don’t have a PSTN gateway) > Next.

15. Choose to Collocate Mediation Server > Next.
16. Don’t add any further server roles > Next > Next.

(Note manually create the share and make sure it has appropriate permissions).

24. Run step one “Install Local Configuration Store” > Select “Retrieve directly…” > Next > Finish.

32. Close the deployment wizard.

Launch “Lync Server control Panel” and Configure

1. Launch the ” Lync Server Control Panel” > Log in with an admin account (created above at step 10).

2. Navigate to Users > Add.

3. Add in your users and assign them to your pool.

Post Install Tasks

1. You need to create a DNS SRV (Service Location) so the client can locate the Lync server:

i. service: _sipintenaltls
ii. Protocol: _tcp
iii. Port Number: 5061
iv. Host offering service: the FQDN of the Lync Server.

Install the ‘Lync Client’ on the client machines.

Problem

I got this error when attempting to bulk create users with CSVDE (see below). But you may simply see it when trying to create a user, or other AD object.

Unwilling To Perform
The server side error is “The directory service has exhausted the pool of relative identifiers.”

Solution

Well that is a scary looking error! Firstly make sure you can see all your FSMO role servers.

Locate your FSMO Role Servers

In my case, I tracked this down to an old DC that has been removed from the domain but was still referenced in DNS. Open your domain forward lookup zone, look in the _tcp container, for any SRV references to old/removed domain controllers and simply delete them.
