[Solved] Call failed due to network issue Microsoft lync when bothendpoints are internal

  6:25 PM    Santosh

While working on Microsoft Lync I have faced "Call failed due to network issue" while making audio/video calls to the users. In my environment I have successfully implemented Lync for IM, audio video conference, Auto Attend, voice mail. But calling was the issue in different scenarios.

Called failed due to network issue
I was not able to able to make calls due to " call failed due network issue" in below scenario,
1. if user is connected Lync from home via Internet and other user is in office network

I was able to make calls if,
1. If I connected to the Office network via Remote Access VPN & other users is in office network
2. If both user are connected to Lync server via internet through Lync edge server.

But call fails if both users in the different network i.e. in office or at home

In my network we have five location & user logs in to the Lync server from different five location via site 2 site vpn or from home via Internet.

Below are the network details of five offices,

Server Network - 192.168.1.0/24
Office 1 - 192.168.1.2/24
Office 2 - 192.168.3.0/24
Office 3 - 192.168.4.0/24
Office 4 - 192.168.5.0/24
Office 5 - 192.168.6.0/24

My Microsoft Lync front end server is in the 192.168.1.0/24 network along with my archiving, monitoring, SQL Server & Edge server Internal facing network card.

TO resolve you have to add routes for your internal network on your Lync Edge server,
My Edge server IP's are
1. Internal
192.168.1.10 Mask 255.255.255.0
No gateway
DNS - Internal DNS server

2. External Facing Network
IP - 10.10.12.10 Mask 255.255.255.0
Gateway - 10.10.12.1
DNS - 4.2.2.2 & 8.8.8.8

My gateway for Internal network traffic for my Edge server is (192.168.1.0/24) is 192.168.1.1 so that it can communicate with the Lync front end server. Same way you need add routes for your other network i.e. offices on your edge server as shown below,

Open Command Prompt on Edge Server & add routes

route add -p 192.168.1.0 mask 255.255.255.0 192.168.1.1
route add -p 192.168.2.0 mask 255.255.255.0 192.168.1.1
route add -p 192.168.3.0 mask 255.255.255.0 192.168.1.1
route add -p 192.168.4.0 mask 255.255.255.0 192.168.1.1
route add -p 192.168.5.0 mask 255.255.255.0 192.168.1.1

Gateway will be the same for all other network traffic. Once you add persistent route restart Edge server & try to make calls.

[Solved] Search for a Microsoft lync SIP enabled users in microsoft Lync client

  9:34 AM    Santosh

If you want to search only Lync sip enabled users in Lync search List then here is the answer. By default Lync address book service scans AD for address book & Lync only adds users to its address book if is able to find or normalize to a valid phone number (E.164). The Address Book service uses the normalization rules in company_phone_number_normalization_rules.txt

But in my case I just want to add Microsoft Lync SIP enabled users in Microsoft Lync client search list.

So lets get start,

Download Microsoft Lync Resource Kit from below URL and install it on front end Lync server.
http://www.microsoft.com/en-us/download/details.aspx?id=21165

Navigate to C:\Program Files\Microsoft Lync Server 2010\ResKit & open ABSConfig.exe

Here I am going to include only Lync SIP enabled users in Lync address book, so in "Only include users that have a value for this AD attribute" should be msRTCSIP-PrimaryUserAddress

Click on Apply changes & close the ABS configuration tool. Wait for 0-24 hours to populate the Lync address book & see the results. Or you can refer below guide to manually change the Lync address book download interval.

[Solved] Lync Contact Search not showing all users

  9:09 AM    Santosh

While working on Microsoft Lync few users reported me that they are not able to view all Lync contacts. Follow below process to solve Lync contact search issue,

1. Open Microsoft Lync management shell & run Update-CsUserReplicatorConfiguration command, This process synchronizes data between Active Directory and the Lync SQL database.

PS C:\> Update-CsUserReplicatorConfiguration -verbose

2. Now run PS C:\> update-csaddressbook -verbose command

Above command trigger the Microsoft Lync Server to synchronize current Active Directory information in the Lync SQL database into the downloadable client and device address book files. (i.e. GalContacts.db & GalContacts.db.idx )

Now Update Lync Clients address book download interval- The address book does not populate itself immediately it takes 0-24 hours to populate the contacts. To change the Lync address book download interval follow below process,

Execute the following command from the Windows Command Prompt to add registry entry (run as an administrator) to change the address book download interval,

reg add HKLM\Software\Policies\Microsoft\Communicator /v GalDownloadInitialDelay /t REG_DWORD /d 0 /f

Now open C:\Users\santosh\AppData\Local\Microsoft\Communicator folder replace Santosh with actual username & delete Lync profile i.e. sip_santosh@mytricks.in OR delete the Lync address book files (i.e. ) i.e. GalContacts.db & GalContacts.db.idx ) from C:\Users\santosh\AppData\Local\Microsoft\Communicator\sip_santosh@mytricks.in (replace sip_santosh@mytricks.in with actual user name.

Close the Lync client completely & sign-in. wait for 5 min & search for the Lync contacts. After login to Lync client you will see the new address book files i.e. GalContacts.db & GalContacts.db.idx downloaded from Lync front end server in your Lync folder.

[Solved] Microsoft Threat Management Gateway The target principal name is incorrect

  11:33 AM    Santosh

Today I faced issue while publishhing my Microsoft Lync Web Services URL via Microsoft Threat managemtn gateway. Everytime while testing TMG website rule I get The target principal name is incorrect error. You can see the below error in detail, Testing

https://lync.domain.com:443/OWA/

Category: Destination server certificate error Error details: 0x80090322 -

The target principal name is incorrect.

After doing lot of R&D I found the solution. I have found any article in detail but few blogs help me a lot. Actually the issue is with Certificate CN (Common Name) used at Lync FrontEnd server (i.e. Lync External Web Services) & Threat Magement Gateway side (Public Name of the URL which we enter while creating web Publishing rule) You need to import certificate on both Lync Front End (use Lync topology builder to apply the certificate) & TMG server. for example your Lync external web services name is lyncweb.domain.com then common name should lyncweb.domain.com with additional SAN which are you going to use (e.g. dialin.domain.com etc). Also ensure Public name of the URL which you are going to enter while creating web publishing rule should match with Lync external web service else it will not work..

In next article I will cover how to create certificate request for TMG & how to import it on TMG & Lync front end server.

Download OS X 10.8 Mountain Lion Developer Preview 4 VMware Image and Run It on Windows 7 Computer

  4:21 AM    Santosh

OS X Mountain Lion Developer Preview 4 was released for developers as build 12A239. To download Developer Preview 4, registered developers will need to log into the developer center and retrieve a download code which can be used within the Mac App Store. Apple's OS X Mountain Lion version 10.8 is the ninth and next major release of OS X, Apple's desktop and server operating system for Macintosh computers.

Apple has hinted at WWDC2012 that Developer Preview 4 was close to the release candidate, and then announced that OS X 10.8 will be available to everyone through the Mac App Store next month for $20. Though DP4 is the most stable beta release yet, it still has a fair amount of bugs and is therefore only appropriate for developers to use.

 System requirements:

  • Mac with an Intel x64

  • 2GB of RAM

  • Language: Multilingual


OS X Mountain Lion DP4 VMware Image Changelog

  • - Apple dropped support for 32-bit mode in DP2 of Mountain Lion, so make sure you keep the VMware Settings flagged as "Mac OS X 10.7 64-bit"  otherwise no bootable medium will be detected. We are currently working on a workaround for this.

  • - Comes with direct download links as usual, should be faster this time.

  • - Completely Vanilla build. Drivers are purely patched Apple files.

  • - Continued new packaging for smaller download.

  • - Fresh installation of 10.8 DP4, everything was fixed during installation.

  • - Make sure VT is turned on in your BIOS, if available.

  • - No comment on AMD systems. Same applies as previously mentioned here.

  • - Reasonably quick boot time, about 1 minute 15 seconds on average.

  • - Recommended you run on the latest version of VMware, as that's what it was tested on, and apparently fixes Apple logo stalling.

  • - Several driver patches to allow as best a universal build as possible.

  • - Snappier system. Clicks receive response almost (if not) instantaneously.

  • - We uploaded an updated VMware Tools to our Mediafire folder here. Hopefully these should work better than in the last 10.8 image.
