Hi Team,

I am facing one issue, I had install one Standard edition Lync 2013 and one Office web Apps server.

However when I am sharing PPT with one user I am getting on message.

" Either you've lost network connectivity or our server is too busy to handle your request. please check your network connection and try again later"

Though network is very fine and only three users are enable on lync server so no overhead on Lync FE server.

Please reply.

your comments are much appreciated.

Thanks.

Hello all,

I am trying to access my internal web scheduler, but I am receiving the attached issue.

What can I do?

dear

my question is that i have a web service joined into my domain and then we  have an exchange server and recently add  lync server 2013(and edg server and sql)

i want register external users(browsing user) in lync server and trying to schedule a lync conference . After creating the conference I send the ConferenceUri to the users and let them join the conference

first i add users into ldap and then enable exchange email for them (by my web ) and now i want enable them in lync and create schedule a lync meeting 

the problem is that i dont know which way is usefull for me? lync sdk , ucma 4 , ucwa , powershell , ...

but all of this ways need an Installed lync server in developing machine .right?

my web service is none hosted lync installed. please help my(in other word i want try that:

http://stackoverflow.com/questions/21019286/schedule-a-lync-conference-with-ucma-3-0

 . how do that?

I'll keep this as short and sweet as possible.  I have found a couple articles but none exactly pinning down what can and can't be done.  Our internal deployment works wonderfully and dial in conferencing works fantasticaly.

I had a couple users that were invited to an external Lync meeting (we don't have reverse proxy, edge, or federation).  Wanting to join from their desktop, the just clicked the "Join Lync Meeting," hyperlink.  Naturally, IE opened and closed itself on discovery of the local client, the client opens and places the user in the lobby.  The user is accepted into the conference but a networking/audio error pops up (Error ID 16389 source ID 0) and states that the call was not completed or has ended and another error "We couldn't connect to the presentationbecause of network issues.  Please try again later.  The user is still in the conference but can only IM, and download the PPT attachment, and no audio is heard.

I like to double check my knowledge and post here while I continue to search for answers.

Can you join an external audio conference from a Lync client, enterprise voice enabled, and see the presented content?  Is it my deployment that is having the issue or is the the external user's?

I hope this makes sense.  Let me know if I can add any "fuel to the fire."

Hi guys. We done Lync pool pairing. Now we have two standard FE and two standard Edge 2013 server.

1st (production) FE Lync server is connected with LyncEDGE1 server.

2nd (test) FE Lync server is connected to LyncEDGE2 server.

All the users are in 1st FE lync server.

We have enabled user2 on LyncFE2 pool.

Internal functionality between users in first pool and with this test user2 in 2nd pool Works, but if we want to make a/v when this user2 connects thru Edge it isnt working.

Lync connectivity analyzer for this User2 passes all the test without errors. Event viewer on client or on any of the four servers does not show any errors. How to track the root of the problem?

With best regards,

I thought Kerberos was enabled in Lync 2013 by default but it's not. Just wondering if it's necessary to enable it and assign it to the site. Seems easy enough to do but was wondering about the downside. Our environment is 3 Lync 2013 FE servers in an Enterprise Pool. 1 PC server. 1 Web Access Server. Still have a single Lync 2010 Standard Edition FE we are in the process of decommissioning and a Lync 2010 Edge. Most of our clients are Windows XP SP3 with Lync 2010 if it matters. Just wondering if its worth it as things seem to working just fine now.

Only reason I found this is I ran the BPA for Lync 2013 and it told me I did not have Kerberos enabled for the Site. Article below does a good job of stepping you through enabling it.

http://howdouc.blogspot.com/2011/07/kerberos-web-authentication-for-lync.html

I've deployed a brand new Lync 2013 environment hosted on Windows Server 2012 R2 that is currently in co-existence mode with my Lync 2010 environment. 
I have SCOM 2012 monitoring the environment and it recently started reporting that one or more of my front end servers
was in a critical state.  Diving into it revealed the following perf counter threshold was being tripped:

Using OCSLOGGER.exe on the front end to capture logs, i trapped the following:

The only recent change made to the front end servers was making the registry change outlined in this article: http://support.microsoft.com/kb/2901554/en-us so i'm wondering if that has something to do with it.

Hi all,

Is it possible to monitor the files sent by Lync from employees? I mean, from the Lync management? And conversations also?

Where is the repository if so?

Does anyone know when the custom intranet site for Lync 2013 will be available? Microsoft had it available for a short time and pulled for some reason. This would be a great tool to deploy in our company for reference when Microsoft makes it available again. 

http://www.microsoft.com/en-us/download/details.aspx?id=42539

Android and iOS clients seem to function normally connected to a Lync 2013 server, but a banner appears saying 'We can't connect to the server... contact your network provider'. Eventually, a dialog pops up saying 'Your administrator has made changes to the Lync Server, please restart Lync.' 

The Windows store Lync client doesn't appear to be affected, and the logs look similar between all three clients. My next step is going to be checking out tcpdump the firewall in front of the Edge/Reverse Proxy servers, but I wanted to see if this was a common issue. 

Hello,

I'm facing some issues with my Ipad/Iphone Mobility Lync Clients.

After they update the client to ther 5.4 version, they cannot connect anymore. I have only internal CA certs published on my Edge and TMG, and also installed the CA Root on the devices, but I keep receiving the "We cant verify the certificate from the server" error. Checking the Logs, I can see that my lyncpool certificate was expired a month ago, but the Policy Listener Tab is populated with a valid certificate. 

Can someone help me?

Thanks!

Hi all,

1. I setup a pool with three Front End servers (FQDN of pool is pool.site1.sip96x2.com and it's pointed to IP address of three Front End servers). Everything works fine. But When I disable network interface on FE1 and FE2, the Lync clients are disconnected. I haven't understood clearly how the Lync clients failed over in a pool? Please clarify to me.

2. I have two central site (Root site and Primary site, they have different domain sip96x2.com and site1.sip96x2.com). The simple URL dialin is pointed to Front End server at Root site. So if the link between Root site and Primary site is down, how can the users at Primary site connect to dialin URL? 

3. In building topology for Front End pool, I checked Override FQDN internal web service and the FQDN is "poolint.site1.sip96x2.com". I created three A records "poolint.site1.sip96x2.com" and pointed to three IP addresses of Front End servers. Is it right?

Thanks so much!

I'm looking for a way to reinstall Lync's performance counters on a 2013 Front End server without having to rebuild the server.

Unfortunately we are unable to restore a previous backup of these counters as they were overwritten before a backup was made. Therefore LODCTR /R doesn't work (even when usinglodctr /r:PerfStringBackup.ini).

This has made it difficult to monitor the environment. We can't even get values when using Get-CsWindowsService. It just returns Unknown values for each service.

I have tried manually to reload some of the counters as with the following example

• unlodctr JoinLauncherPerf
• lodctr .\JoinLauncherPerf.ini

All looks ok. No errors, but after restarting the Performance service I end up with one if not all the following errors in the event log.

• "Disabled Performance Counter X from the X service because the performance counter library for that service has generated one or more errors...."
• "The configuration information on the performance library X for theX service does not match the trusted performance library information stored in the registry...."
• "Unable to read the first counter index value from the registry"
• "Windows cannot open the 64-bit extensible counter DLL X in a 32 bit environment....."

I've been searching high and low but can't find any definitive list or script to reinstall these.  Can anyone assist?

Running on WinSvr2012, Lync Server 2013 with October2013 CU. 2 node Enterprise Front End pool.

Hello,

We have a working Lync 2013 deployment:

- Front-End Enterprise Pool consisting of 3 FE servers

- one Edge Server

- one Back-End server

- one Mediation Server

- one IP PBX gateway, where ITSP's SIP trunks end.

Because we have geographically distributed offices, we are considering deploying of branch offices deployments.Technet recommends to use SBA for branch offices where there are less than 1000 users. But in case of WAN outage, no conferencing will be available for branch users.

Lync 2013 Standard edition branch deployment would offer all Lync features in case of WAN outage.

In every branch, we consider deploying a Cisco ISR G2 router for terminating branch SIP trunks. This equipment have option to add Cisco UCS E-Series blade that supports CPU with hardware virtualization and supports decent amount of RAM (up to 16GB and up to 48GB).

Have anyone experience with deploying Lync Standard Edition on this equipment - Cisco UCS E-Series blades? In every branch office there are up to 50 - 500 users that will use Lync.

Thanks,

Andrei Moraru Endava

I have a customer who have Lync Enterprise with 3 Front ends and SQL Backend and Mirror 

On Frontend 1 the command "Get-CsDatabaseMirrorState -PoolFqdn lync.domain.com" reports that all databases state are unavailable while on Front end 2 and 3 it states normally "principal and mirror"

I couldn't detect any errors on either Frontends or SQL Backend or Mirror. the Monitoring tool from tasks on SQL Management states that databases are syncing. 

I have tried restarting the Frontend 1 but still the issue occurs. anyone had this problem before?

We've installed Lync on a single server in our lab environment and have it connected to the domain (mydomain.com). In order for external users to connect to it, what are the basic DNS settings required on our internal DNS/AD server and what entries are needed to be published to the external DNS provider?

There are currently only two servers in this environment, the exchange/AD/DNS server and the Lync Server. The exchange/AD server is currently running Windows 2008 SP2 and the Lync Server (2013) is running Windows server 2012.

Thanks.

I am attempting to have "open federation" set up.  By "open federation" I mean that the check box that says "Enable partner domain discovery" under Access Edge Configuration in the Federation and External Access tab of the Lync admin console is checked.

Every attempt to contact another organization that also has open federation gives me the ambiguous error of "When contacting your support team, reference error ID 504 (source ID 239)".  It also does not update anyone's presence.

External access is working well for our users.  The Windows 7 clients can get in through the edge when disconnected from the network.  Everyone can get in through their phone clients whether they are connected internally or not, which is great.

The cert on the external interface of the Edge is publicly trusted and it is not a wildcard.  The SANs are correct.

The remote connectivity analyzer at https://testconnectivity.microsoft.com/ gives all green check marks for every test, though it appears that this test has nothing to do with federation.

I went to http://www.lyncdirectory.com/ and tried to make contact with a few usernames listed there and the exact same behavior happens.

I've been to https://greiginsydney.com/decoding-lyncs-client-side-error-messages/ and gone through this list of possible problems:

1) If you’re trying to contact a Federated party, your Edge server is down. (Try a different Federated partner to check this).

My edge server is not down.

2) If you’re trying to contact a Federated party, then their Edge server is down. (Try a different Federated partner to check this).

Their edge server is not down.

3) If you’re trying to contact a Federated party, this might be because you’ve added a new SBA or Front-End server to your Lync deployment but you’re still using an OCS Edge, and you haven’t added the new server to the Edge’s “trusted servers” list. (All the instances of Error 14502 in the Event Log on the new Lync server are a giveaway too!)

I haven't added anything...this is a new deployment so it's never been working yet.

4) Asynchronous routing / bad config. If you can receive IM’s from someone and get this error when you reply, check their system’s external DNS or Edge config. Look for wrong or mis-configured DNS or NAT in the Topology.

I don't know if someone can IM me.  I don't think so.  I doubt it's a problem on their end.

5) Check ALL the certificates in the chain between you and the other end. In a recent example, one of the intermediate certificates in the initiating party’s cert chain had been renewed, and this new cert wasn’t trusted by the remote end. Error 14428 on the recipient’s Edge server confirms this issue – “The certificate chain was issued by an authority that is not trusted”. (This is an ongoing drama at the time of writing, as it seems very few Lync Edge servers trust this new intermediate cert).

I can't check other people's certificates.  I can't check other people's event logs.

6) The Edge at the far end doesn’t have a Hosts file entry for that user’s front-End or SBA. (This scenario will manifest itself as “1-way IMs” – you can start an IM conversation with the remote party all OK, but if THEY initiate a conversation to you, YOUR IMs will always receive a 504/239 – but you’ll still receive their messages. This occurs because if you initiate, your establishing IM goes to the remote Edge’s Next-hop server, which IS known to the remote end’s Edge, and from there it’s on forwarded to their registrar).

I suppose it is possible that everyone in the world is set up wrong and I'm the only one that is set up right, but it just seems ridiculously unlikely.

When I run a trace on OCSLogger on the Edge, choosing SIPStack, all info, all flags, and then replicate the error, it logs nothing but a blank text file.

I did the Skype provisioning process a while ago.  I don't know anything about Skype so that doesn't help, but when I log into Skype on my Windows phone and try to message myself on Lync, I don't get anything, not even presence.  Same when I go the other way.

I don't know what ports to check.  I have an SRV record in the external DNS that is _sipfederationtls._tcp.mydomain.com . 

My client log says something about the server timing out when I try to message an openly federated partner.  I've even added his domain explicitly to the trusted federated partners list in the admin console, and it has no effect.

I don't know what else to check or what else to try.  Can anyone help?

Thanks,

Brandon

Must be some kind of cruel joke... 

In Lync 2013 client there is the option under "Help your support team help you" forAlso turn on Windows Event logging for Lync to collect troubleshooting info.

This sounds like a great little feature... except... when you turn this on, events with absolutely zero useful info start getting logged in Event Viewer:

Example:

The description for Event ID 3 from source Lync cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

Lync
lyncserver.company.com

What gives? We are using the Lync 2013 SP1 standalone install (not the whole Office 2013 suite). Office 2010 is being used for all other Office apps. Client has been updated to latest and greatest.

Hi,

I am deploying Reverse Proxy Server using ARR for publishing Lync 2013. I have added following servers in server farms:-

1. dialin.domain.com

2. meet.domain.com

3. lyncdiscover.domain.com

4. lyncweb.domain.com

5. wacsrv.domain.com (office web apps server)

I am confused over the following:-

1. My internal domain is .local, i.e. my front end server is fes.domain.local. In this case, how my reverse proxy server will resolve my internal server names? do I need to add static mapping using host file?

2. Will dialin, meet, lyncdiscover, lyncweb point to Front End Server?
