Desktop sharing not working after firewall change

October 25, 2016, 7:42 am

We have a problem where a user that's not on premises uses Lync to connect, off VPN, with an internal user, they cannot share their desktop or an app. IM works but sharing does not. Note the user is not tunneled in using VPN so I assume they are going through the Edge server. The other user is connected with a VPN.

Further, when both users connect off VPN, through the Edge, it works, so to me, it looks like inbound traffic from the internal NIC on the Edge to the FE server(s). This used to work until we had a firewall change so I am guessing networking missed a couple of rules. I tried to figure it out using the Microsoft Poster diagram but could not. So, what ports do I need open between the Edge and the internal FE for this to work?

Everyday morning when I signon to Lync it is asking me to login and save password prompt. Even when I reply in affirmation it does not seem to be saving it and next day it is again asking the password. 

Is this a bug in Lync 2013?

Lync 2013 required ports and external dns records

Hi All,

I need to help your about a situation, I'm confused about which ports must be open to lync roles. I have deployed lync servers and seperated roles. for example.

1 - frontend server : 192.168.100.1

2 - backend server : 192.168.100.2

3- edge server : 192.168.100.3(internal),  192.168.100.4(external) and nat ip 31.185.147.x

4- Revers Proxy with iis arr : 192.168.100.5

Lync is working in internal successfuly,but for external access which port must be open and ı'couldnt't find acceptable a document.

in this environment; I redirected the following ports to edge server but users can login to lync but they cant change presence status,They look like offline or last login status if they connect from wan

Someone tell me which ports must be redirected from wan to which server that has lync role ?

1.Edge server : 443,5061,4443,5269,23456,3478, is it enough ? (for wan)

2. Reverse Proxy server : ?  ports (for wan)

3.Front end server : ? ports (for wan)

Also ı have created external dns records sip,tls,xmpp,lyncdiscover on hosting.

Thanks in advance

Lync Server Stress and config tool Ad-Hoc option detail explanation needed

What does Ad-Hoc option under 'General Scenarios' does?

Say, I select below two load options:-

(a) Audio Conferencing:- Load Level - HIGH; AdHoc - DISABLED; Large Conf - ENABLED

(b) Audio Conferencing:- Load Level - HIGH; AdHoc - ENABLED; Large Conf - ENABLED

How the load will be different in above two cases? Will the amount of load OR number of audio conference/calls be different in above two cases?

Microsoft documentation (https://technet.microsoft.com/en-us/library/mt631406.aspx) says, ChoosingAd-hoc will allow the tool to generate simulation of conferences that will be created throughout the hour; which is not clear to me.

Unable to assign Lync OAuth Certificate

March 27, 2014, 8:10 am

I am currently unable to renew my Lync Server 2013 OAuth certificate.

Assigning this through the wizard or shell completes without any errors but the new certificate is not shown in the wizard or shell and an event is logged under the replication service to say that the replication failed.

This appears to be the same error reported in http://social.technet.microsoft.com/Forums/lync/en-US/6e4b15f7-16a2-48d9-9cbe-1fc3ff8cf432/lync-server-2013-rtm-cannot-assign-oauth-certificate?forum=lyncdeploy and I've copied this in below.

The replication of certificates from the central management store to the local machine failed due to a problem with certificate processing or installation on the local machine Microsoft Lync Server 2013, Replica Replicator Agent will continuously attempt to retry the replication. While this condition persists, the certificates on the local machine will not be updated.

Exception: Microsoft.Rtc.Management.Common.Certificates.CertificateException: Keyset does not exist

Cause: The certificate provisioned in the central management store is invalid or cannot be handled on the local machine.
Resolution:
Ensure that certificates provisioned in the central management store are valid, have all needed issuer certificates included or installed on the local machine, and can be used with cryptographic providers available on the local machine.

There was a certificate in place for this previously but this issue was shown when trying to renew the existing certificate. I then removed the existing certificate and tried to add the new one but had the same issue. I also had the same issue when trying to re-import the certificate which was previously in use.

I have tried renewing through the Lync wizard and directly through the CA.

I have tested replication using get-csmanagementstorereplicationstatus which shows no issues.

There is only one front end server in the topology which is on Server 2012. The edge server is not using this certificate.

I have also tried using the domain wildcard certificate which has the same issue.

I'll update this with more detail and clarity if I can.

Thanks in advance!

Skype For Business 2015 Server - Management pack for SCOM (System Center Operations Manager)

Hey!

We recently updated our Lync 2013 Servers to Skype For Business Server 2015, after that the monitoring from SCOM stopped working. So I was looking for the new Skype For Business Management Pack but I can't seem to find it.

The only information I find about it, is this:

"

System Center Operations Manager is recommended.  We recommend that you monitor the health of your Skype for Business Server deployment to help ensure service availability for end-users. You can use the System Center Operations Manager Management Pack for Skype for Business that is available as a free download from Microsoft. With the Skype for Business Management Pack, you can proactively get real-time alerts when issues occur, run synthetic transactions to test end-to-end Skype for Business functionality, get reports for service availability, and so on.  This helps you to proactively respond to issues with your deployment before end-users experience them.

"

I have searched all around Microsoft Download Center, but I can't seem to find it.

Have somebody else located it, or maybe have some information about the release of it?

Thank you for your time!

Hello,
Skype for Business Server 2015 (front-end) sometimes reports this error on Event Viewer => Application and Services Logs => Lync Server:

  • Source: LS User Services
  • Event ID: 32263
  • Description:

    An error occurred while processing a batch of NotifyPipe replies from another front end. This resulted in the notification not being sent. Error code: 0xC3E93C2F(SIPPROXY_E_UNKNOWN_USER_OR_EPID), Error identifier: NotifySingle.Notify Cause: Possible issues with the other front end or with this front end.

One of our customer is getting annoyed because even if we disable any user from Microsoft Lync Server 2013 control panel and remove from distribution group(Corporate directory) it still displays in contact list. User only has to logout and sometimes has to delete sign-in info for sync up.

Can anyone tell me approximately how long Skype for Business client takes to sync up with Lync server? and is there any other solution if user doesn't want to sign out and delete sign in info?

Thanks & Regards,

Need help with Holiday Sets

Hello, I have a client that has many (around 40) IVR Response Groups. Most of them have more than four questions, so I have to manage them using PowerShell.

I need to create new Holiday Set for 2017 and assign it only to the Response Groups that use Holidays. Not all of them have Holidays assigned.

I have a few questions.

1. How do I find using PowerShell if IVR has Holiday Set assigned to it?

2. Is there a script that checks and if there is a "2016 Holiday" is assigned to IVR, and, if it is assigned, adds "2017 Holiday" Holiday Set?

Can someone help me with this?

Thank you. Eric.

Lync Eventid 32174 / 32178 - Frontend does not start

Hello,

I keep on getting Eventid's 32178 and 32174 with errors

Server startup is being delayed because fabric pool manager has not finished initial placement of users.

Currently waiting for routing group: {EF5151C7-B5E1-53B8-9F61-0CC90C82B9F6}.

Number of groups potentially not yet placed: 7.

Total number of groups: 7.

Cause: This is normal during cold-start of a Pool and during server startup.

If you continue to see this message many times, it indicates that insufficient number of Front-Ends are available in the Pool.

Resolution:

During a cold-start of a large Pool it can take upto an hour for the placement process to finish as it needs to populate all the Front-End databases with data from the Backup Store. If the Pool is running and the Front-End is just started, this is normal for some time. If this repeats for a long time, ensure that all the Front-Ends configured for this Pool are up and running. If multiple Front-Ends have been recently decommissioned, run Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery to enable the Pool to recover from Quorum Loss and make progress.

I already tried the QuorumlossRecovery, but this doesn't work since the FrontEnd won't start. I also removed all intermediary certificates that were in the root certificates. Renewed the certificates using the Lync Configuration tool, but this didn't fix it.

I'm totally at a loss here on how to solve it. Will upgrading to SfB 2015 solve this?

Hi

Today I started upgrading my Lync 2013 Frontend Pool to Skype for Business. Unfortunately it was not succesfull. All three Frontend servers encounter the same error. The error is at the end of the installation in the verifing of the installation:

Error encountered: "Replica" is not member of "RTC Local Config Replicator"."RTCCLSAGT" is not member of "RTC Component Local Group".
Component "Replica" is not installed on "FrontendserverName".

Are there any ideas to fix that? I checked already the permissions. The System was working fine, before the upgrade.

Dear Admins,

New to this topic and I'm going through the Doc Microsoft Lync Server 2013 Step by Step for Anyone   by  Matt Landis, Lync MVP. However just got a doubt , while creating the Topology we install SQL Express Edition in order to enable the basic features.

But I heard in order to add/enable the new features(like voice/lync meetings/voice) in existing Lync server environment we need a standard or enterprise edition of SQL DB to be installed.Could you please guide in getting the right way to integrate the standard/enterprise DB with the Lync server 2013.

Hi

I have a new user and their account was created the same way as everyone else, but Lync will not allow them to sign in. 

If i change their domain from user@domainA to user@domainB then they can sign in. All other users in domainA can sign in no problem. I have checked the SIP address matches the users email etc and have removed them from Lync and recreated but its still not allowing them to sign in. The error they get is below: 

Cant sign in to Lync: You didn't get signed in. It might be your sign in address or logon credentials, so try those again. If that doesn't work, contact your support team.

Any ideas?

Cheers
