Any guides how to deploy Lync 2013 to one AD Domain/Forest with multiple sites? HA is in mind... What servers need to be deployed to sites and how to do the configuration?

Hei sorry for not answering sooner. If you just install Lync 2010 standard then all u need is dc (as in domain) + 1 server to install Lync itself (standard). If u want high availability then Enterprise version is the way to go. With enterprise you can create pools of frontend servers for instance (with dns triks thouse pools work as load balancing). Also some spoilers from the next version: http://www.zdnet.com...ore-7000001415/ ---> Consolidation of roles; no separate server role needed for monitoring and archiving. Also if memory serves u cant select your own (remote) sql when using Standard (this could be lie as i dont remember no longer).

Hi Everyone, I have question regarding Windows Server 2012 R2, that is it possible for us to reset windows server 2012 r2 to factory reset like microsoft client operating systems (7,8,10). If yes can you please help me out, how? Regards RMA

Will there be a new guide for Lync 2013? This guide was amazing. Want to test Lync 2013 (Home Lab) for learning. Hope you will help us with a new guide for Lync 2013.

The link to http://policelli.com/Files/Deploying_Lync_Server_2010_Enterprise.pdf seems to be dead. Can you up it somewhere please?

The first big change is the Lync GC client has be re-written to support Lync standards such as it leverages the Unified Communications Client Platform (UCCP) API and Microsoft Unified Communications Managed API (UCMA) 3.0. The look and feel are similar to GC in OCS R2 however there are some changes: The Group Chat user interface and its accompanying icons, including its emoticons, have been upgraded and resized to match the Lync 2010 Group Chat user interface. Colors, notifications have been enhanced as well. Can open multiple GC windows Tweaks to the Ego filter such as: The Ego filter no longer triggers whenever you type “IT”; for example, “Sara Davis (IT Dept)”. The text can be excluded only if the “bracket pair” in question is closed. For example: “Sara Davis (IT Dept)” becomes “Sara Davis” “Sara Davis (IT Dept” becomes “Sara Davis IT Dept” “Sara Davis [iT Dept (HR Unit)” becomes “Sara Davis IT Dept” Other enhancements include: Unicode support – Support for Arabic, Chinese, and other UTF-8 languages Client side logging disabled by default- to save disk space Enhanced GC health monitoring via an SCOM management pack for the following: Group Chat Channel service Group Chat Lookup service Group Chat Compliance service Is federation still supported with Lync GC?

In Lync 2013 group chat rooms are now integrated --> Persistent chat (or group chat) becomes a "full-fledged" Lync service, not just a bolted-on add-on --> http://www.zdnet.com...ore-7000001415/

Figured out that this was due to a misconfiguration in the SIP gateway. Now I'm dealing with: The Mediation Server service has received a call that does not support comfort noise from the Gateway peer, 1.1.1.1 (SIP gateway IP) Cause: The Gateway peer does not support comfort noise. Resolution: Please ensure the comfort noise option on the Gateway has been enabled. And this: Unexpected exception occurred in the Inbound Routing Application. Exception: System.DirectoryServices.ActiveDirectory.ActiveDirectoryServerDownException: The RPC server is unavailable. Name: "domaincontroller.mydomain.local" at System.DirectoryServices.ActiveDirectory.Forest.GetTrustsHelper(String targetForestName) at Microsoft.Rtc.Internal.ExumDialPlanData.GetTrustedForests() at Microsoft.Rtc.Internal.ExumDialPlanData.RefreshDomainDictionary()
