Can not run DHCP utility in Windows Server 2012 for Lync 2013

Recently while deploying Lync 2013 for client I came across this little issue.

I copied  DHCPUtil.exe and DHCPConfigScript.bat files as usual to DHCP Server and try to run DHCPUtil.exe but got following error

 

 

To solve this issue, go to "C:\Windows\System32" on your Lync server and copy msvcp110.dll and msvcr110.dll and paste it in System32 folder of DHCP Server.



Enable IM Mute

Turn off IM in a Lync Meeting (Enable IM Mute)

Turning off instant messaging (IM) in a Lync Meeting allows you to help participants stay focused on the meeting content. You can disable IM when scheduling the meeting or during it.

Keep in mind that when you disable IM at the time of scheduling, you can’t turn it back on during the meeting. But if you turn off IM during a meeting, you can turn it back on at any time, to allow shared conversation.
To disable IM when scheduling, you must have Outlook.

Disabling IM when scheduling a Lync Meeting

1. On your Outlook ribbon, click New Lync Meeting.
2. Click Meeting Options on the ribbon.
3. Under Do you want to limit participation?, click Disable IM.
4. Click OK and set up the rest of your meeting as you normally would.

Disabling IM during a Lync Meeting

Any of the presenters can turn IM off or on during the meeting, if it hasn’t been disabled at the time of scheduling.

1. In the meeting window, point to the people icon.
2. Click the ACTIONS tab
3. Click No Meeting IM.

Lync notifies the meeting participants that the IM has been turned off.

To turn IM back on, go back to the ACTIONS tab, and click Allow Meeting IM.

The Device Update Process

---

The device update process begins with you downloading an update from the Microsoft website, and then using the Lync Server 2010 Control Panel to test, approve, or reject the update. Approved updates become pending updates that devices retrieve by using the following process.
The first time a user starts an IP phone and signs in, the device gets information by using in-band provisioning from the server. The information contains the internal URL of the server running the Device Update Web service.
If the device is turned on, but no user signs in, and no user has ever signed in on the device, then the device sends a DNS lookup request to ucupdates-r2.<DNSDomainNameProvidedByDHCP>, and obtains the internal URL of the server running the Device Update Web service.
The device checks for updates every time it is turned on, every time the user signs in, and every 24 hours, by default. It checks by sending an HTTP request over port 443 to the Front End Server that hosts the Device Update Web service. The request includes the current version of software that the phone is running, and the response is determined by the device and whether there is a new update on the server to download.

Lync Edge Server - RSS configuration

One of the note on TechNet ( http://technet.microsoft.com/en-us/library/gg615015(v=ocs.15).aspx) recommends following

To improve the performance of the A/V Conferencing Edge service on your Edge Servers, you should enable receive-side scaling (RSS) on the network adapters on your Edge Servers. RSS enables incoming packets to be handled in parallel by multiple processors on the server. For details, see http://go.microsoft.com/fwlink/p/?LinkId=206013. For information on how to enable RSS, see your network adapter documentation.
