Using Lync 2013 client with OCS2007 R2

August 1, 2013, 1:03 pm

We are in the early planning stages of migrating from OCS2007R2 to Lync 2013. My laptop originally had Office 2010, then upgraded to Office 2013 long ago and already had Lync 2013 installed. When I noticed that Lync 2013 client could be massaged to conenct to OCS2007R2 server, I wanted to test it. My laptop is current on Windows patches and Office 2013 patches (according to OffCAT 1.1).

When I launched Lync 2013, the splash screen would come up and then go away, and nothing else would happen. Exited the Communicator client, no change. Uninstalled the Communicator client, no change. Repaired Office 2013 installation, no change. Removed and re-installed Lync client, no change.

The person who setup the prior OCS environments left the company a few years ago. I have updated the OCS2007R2 with all WIndows patches as well as using the ServerUpdateInstaller.exe to patch OCS2007R2 to the requested level. OCS2007 Best PRactices analyzer says I'm missing two critical hotfixes, 977343 & 977344. I installed both but the BPA still says they are missing. BPA also barks about VMware.

BPA also warns about a number of missing SRV records. The missing SRV records are _sipinternal._tcp, _ntp._udp., _sipinternaltls._tcp., for a couple different domain controllers, and for our NT4 domain, our AD domain, and for our primary e-mail domain (different from AD domain).

I found a two different articles regarding how to make Lync 2013 connect to our legacy OCS2007R2 environment for testing.

http://alberthoitingh.wordpress.com/2011/05/23/using-the-new-lync-client-to-connect-to-office-communications-server-2007/

http://alberthoitingh.wordpress.com/2013/03/04/lync-2013-client-and-office-communications-server-2007-r2/

I've created both of these keys and rebooted, but the client will still not connect. Where do I go from here?

Lync 2013 and failovers?

August 14, 2013, 4:26 pm

Hi, having an environment with two Lync Server 2013 Front-End servers with 1 SQL server as backend.

I know one should have at least three front-ends to make full use of windows fabric but since 2 front-ends is supported, tons of customers are demanding it... :/

So I'm sitting here doing some failover tests and I don't know the procedures and the things involved here but I thought was that if I restart lyncfe01, the other server lyncfe02 will become registrar and have all the routing groups moved to it, where the users belongs?

But when I restart lyncfe01 which my testclient (Lync 2013) was connected to, it takes like 30 sec before it disconnects (logs out) and in the meantime I cannot chat or do anything. after the client has been disconnected it takes about another 30-40 secs before it reconnects and logs in again.

Is this the way it should work? And has it anything to do with us using only two front-ends instead of 3 or more?

DNS RR for lyncpool01.company.com wich points towards both lyncfe01 and lyncfe02.

HLB for all HTTP related traffic.

Please give me some hints here, since both me and my customer was in the understanding that clients would not notice any server failure, or at least a minimum if a front-end went down...

Lync 2013 SE - Backup service on paired pool

August 14, 2013, 6:18 pm

Hi there, we have two geographically dispersed sites, with a single Lync 2013 Standard Edition server in each site. The servers are paired, with Site A holding the CMS. 

Should we be having both sites point to each other as an Associated backup pool, or is it enough to have Site point to Site B as the backup pool, and that will replicate both ways?

The reason I ask is because I see these errors frequently about the backup service (we have both sites pools pointing to each other as associated backup pool):

Microsoft Lync Server 2013, Backup Service central management backup module failed to complete import operation.

Configurations: 
Backup Module Identity:CentralMgmt.CMSMaster
Working Directory path:\\siteB.domain.local\share\1-BackupService-17\BackupStore\Temp
Local File Store Unc path:\\siteB.domain.local\share\1-BackupService-17\BackupStore

 Additional Message: 
 Exception: Microsoft.Rtc.BackupService.ImportOperationException: Import operation (from zip archive \\siteB.domain.local\share\1-BackupService-17\BackupStore\CentralMgmt\CMSMaster\Data\Backup.zip) is failed due to: Failed to execute stored procedure XdsUpdateReplicaData.

Lync Server 2013 broken after Windows Update - Could not load type 'Microsoft.Rtc.Server.Infrastructure.Interfaces.ICachingLookupUser'

August 14, 2013, 6:04 pm

Hey there,

    My Lync 2013 Server installed Windows Updates last night and is now broken.

The problem is all the websites are broken with ASP.NET 4.0 error like:

Server Error in '/Autodiscover' Application.

Could not load type 'Microsoft.Rtc.Server.Infrastructure.Interfaces.ICachingLookupUser' from assembly 'Microsoft.Rtc.Server.Infrastructure, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

This error seems to be present on all the IIS websites on the machine.

I would uninstall the WIndows Updates, but after reading a little it seems a few of them have updated the schema of the Lync database so I am reluctant to do a full rollback and restore the databases from yesterday.

I have IISRESET, and rebooted the box a few times, but still the ASP.NET error persists.

I have also re-run the component deployment from the Lync deployment wizard.

Any advice you be helpful!

Cheers,

   James.

Setting up certificates in Lync

I'm setting up the Lync Front End Server and am not sure how to proceed with assigning certificates.  In the window where it prompts to select a CA the first option to select a CA from the list detected is blank.  I can select the other option but not sure where to point it.  My DC or the same Front End server?

Media Bypass - Use Site and Region Information - What about subnets not configured in Sites and Regions?

August 15, 2013, 7:42 am
$
0
0

Hi All,

with Media-Bypass you have the option to "Use Site and Region Information". Depending on the site and region information defined in there, if the Bypass-Id of the Client subnet is the same as the one of the subnet where the PSTN Gateway lives, then Media Bypass is used, otherwise the call goes via the Mediation Server.

My question is: What happens when a Lync Client is located in a subnet that is not part of the sites and regions configuration in Lync? I assume that if the Lync Client subnet is not configured in there, a call would go via Mediation Server. Is that correct? - Or does Lync rather go and say "well I dont have this subnet in my configuration, so I can not calculate a Bypass-Id, so lets try to use Media Bypass"?

Background to this question is: Regarding Media-Bypass, do I have to configure all of the subnets of a large international Company in the Sites and Regions configuration or will it be sufficient to configure the regions and sites where Gateways are located that should support Media-Bypass?

Many Thanks in advance,
Hanno98

Associate Front End or Mediation pools

Hi Just a question i think i know the answer we are doing a new lync 2013 install and we have a front end server and separate mediation server so NOT collocated when we are installing the edge server it is asking us to associate front end or mediation pool for external media traffic.

i am assuming we only need to associate the front end pool or do i need to associate the mediation since my nic to my sip provider is on the mediation. Or do i need both.

thanks

Well connected WAN defined?

Hi All,

to use Media-Bypass across WAN Connections you need a well connected or low latency WAN.

What exactly is the definition of this? I read you need a roundtrip time of below 25ms. What else? Probably some jitter and packet loss constraints?

Many Thanks in advance,

Patching Problems - Diff Patches, same symptoms

August 16, 2013, 3:57 am

I recently installed all the current Lync patches to my 2013 Lync server running on Windows Server 2012. 3 of them produced issues and all 3 displayed identical event log warnings and inability to access Lync via the mobile app.

  • KB2819565 - Update Rollup - Failure to start front end service plus inability to access Lync via the mobile app
  • KB2835432 - Core Components Rollup - Inability to access Lync via the mobile app
  • KB2835435 - Web Components Server - Inability to access Lync via the mobile app

All 3 patches would spam RestartManager messages in the event log during install followed by persistent ASP.NET unhandled exception warnings after install was complete, all relating to components within the Application path under the Web Components pat of Lync Server. IIS logs show various errors but mainly http response 500's. 

I'd like to know if anyone else has seen this as I'm concerned the patching simply exposed an underlying problem on my installation rather than the patches themselves being at fault. 

In all cases rolling back the patched fixed the issue. Several other Lync patches installed successfully.

Thanks,

Jamie.

Hey Guys,

I had the custom presences working fine and available to everyone in the policy prior to the CU1 updates, after which they are not available. I have had the exact same thing happen at a remote site on a different server.

Other than that everything else works fine, the security certificates seem to be fine and everything else works and signs in as normal, there is no evidence of any problems in the logs, any ideas?

Thanks in advanced,

I have a Lync Server 2013 Standard FE server setup on the network with no Edge or Reverse Proxy servers.  It's using an internal certificate issued by internal CA.  Lync Client 2013 is able to connect on the workstations that are on the domain.  However I'm not able to connect using mobile devices that are connected to the intenral WiFi on the same network.  Do I need to setup Edge Server for mobile devices to be be able to connect even if it's on the internal WiFi?  My understanding was that Edge and Reverse Proxy Servers were only needed for external access..

LS Storage Service cannot start and prevents Lync Server 2013 Front-End service to start

Hi All,

We have Lync 2010 Standard deployment in production.
In the way to migrate to Lync 2013 Enterprise we deployed pilot additional pool.
Created and published new topology with one Front End in one Back End server.
RtcSrv (Lync Server Front-End) cannot start.

To localize an issue I deployed pool in the Ignite lab environment (http://lynclabs.vlabcenter.com/Signin?ReturnUrl=%2fMain) and compare logs for successfully starting pool and our pool.

They are pretty similar until the event “Storage Service is starting (32002)”.
In the working environment the next event is:
Log Name:      Lync Server
Source:        LS Storage Service
Date:          7/22/2013 12:49:13 PM
Event ID:      32009

                Connection Reset    = false;

LYNC 2013 Client - signed in but still prompting 'network password required to connect'

We are currently half way through our OCS 2007R2 to Lync 2013 migration, with the following servers for basic IM and Presence internally, and federation with one external domain.

OCS 2007 FE server

OCS 2007 Access Edge Server (in DMZ and only used for IM and Presence with one federated domain)

Lync 2013 FE server

I have 3 accounts migrated over to  the Lync 2013 server and all features we require are working AOK. IM/Presence/Desktop Share/ File transfer/even the federation with our partner domain.

However,  Lync the 2013 clients continue to prompt "Network password required to connect. The network you are connected to requires a password before LYNC can contact the server"   The server shown is our proxy server, so even though it's signed in and working as required, it's trying to go out to the internet.

On our Forfront TMG it looks like this is the point of failure: "Request: GEThttp://autodiscover.ourdomain.com/autodiscover/autodiscover.xml"

All of the features we require are working well without entering proxy credentials. (simply hitting cancel)

Is there a configuration on the LYNC side that I can make to address this?

I've getting this error on one of my front end servers. I have three front end servers (FE0101, FE0102, FE0103). Only on FE0101 is the front end not started/starting.

The error message says ensure that 85% of the front ends configured for hte pool are up and running. Now I didn't run two front end servers to try to avoid this problem but three servers (one being down) is only 66%.

So is three servers not recommended either?!?!

Problems with Lync Server 2013 FE Address Book Server

Hi,

When I'm running the Update-CsAddressBook on the FrontEnd I end up getting an event log error

"Users are not indexed in the database that should be.

Expected indexed user count: 0
Actual indexed user count: 1172
Cause: User replication issue.
Resolution:
Run Update-CsAddressBook to synchronize all accounts."

I also get other errors but there seems to be something badly wrong with the Address book server. If I try to access https://myfe01.mydomain.com/abs/handler URL from a client I get 400 Bad Request. All users also get an authentication dialog if trying to open that location using a browser. After punching in the credentials the users get 403.0 - forbidden error.

This worked at first (a couple of clients have GalContacts.db and GalContacs.db.idx in their AppData, how ever if this is reset they don't get a new copy), but now it doesn't work for anyone.

How could I get this working? Any help is greatly appreciated!

Cert nightmares.. Godaddy UCC and Lync is attempting to connect to vslync01.domain.local cert details lyncdiscover.domain.com

I get this error when a client connects on Lync 2013..

I'm assuming its because our sip domain is the external one.. the domain.com, we dont sign in with domain.local..  

The cert is a 10 UCC from godaddy, but it does have a SAN entry for vslync01.domain.local included.. the common name is lyncdiscover.domain.com

I would have thought that since the .local address is in the SAN in the certificate, this error would not happen or go away.. but it isnt the case..

Any thoughts on an easy fix?

Thanks in advance
