Receiving http 502 BadGateway Response Error when testing Lync 2013 using iis arr

I'm currently getting this error when i use testocsconnectivity.com

Testing HTTP authentication methods for URL https://lyncdiscover.mydomain.com/Autodiscover/AutodiscoverService.svc/root/user.

HTTP authentication test failed.

Additional Details
A web exception occurred because an HTTP 502 - BadGateway response was received from IIS7.
Content-Length: 1477
Content-Type: text/html
Date: Tue, 23 Jul 2013 16:15:57 GMT
Server: Microsoft-IIS/7.5
X-Powered-By: ASP.NET

What I've tried/works so far:

lyncdiscover resolves, the port opens, and the ssl cert validates.

When I try and get to meet.mydomain.com from an ipad (externally) i get another 502 error. It says:

502 - Web server received an invalid response while acting as a gateway or proxy server. 

There is a problem with the page you are looking for, and it cannot be displayed. When the Web Server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.

I think it might be something on the external web site on the front end, but it's already certed with the appropriate SANs and I don't know what else it could be regarding that.

Another possibility which i found was to check the enable proxy box under the application request routing module under the iis manager.  This seems like it could be my problem, but I found no mention of it in any of the guides I've looked at.

I mainly used the NextHop guide by Koen Wagenveld

Lync Server 2013 "decommission"

Hi!

At my current company we are planning to do an Office 365 – Exchange 2016 hybrid deployment and we have a single Lync Server 2013 for internal communication only. There is no edge server, no public SIP DNS records and the users sign in names looks like this: username@companyname.intra. I found a few documentations for configuring hybrid Lync servers then decommissioning the on-premise servers, but I think that those documentations don’t apply here, because our Lync server is not fully functional. I have an idea about “decommission” for our server, but I don’t know if I’m right about this. So, I am planning to sync the users to O365 with AAD Connect to O365, then delete the users from the Lync server then sync again, this way the users local SIP address will be deleted from O365 and immediately assign the users the appropriate O365 license and when I finished with the last user, I simply turn off the on-prem Lync server. Is this going to be ok, or I need to do a hybrid deployment for Lync too? I know that probably this is not supported, and there is going to be a service outage.

Thank you for your answers!

Best,
David

Exporting content of Conference Directory

Doing post migration tasks after a Lync 2013 to SFB 2015 migration. I have two Conference Directories and I am not sure if I should move them or not. I exported them out to .xml files but I don't know what I am looking at. Is there anything specific I should be looking for?

I don't know if there is any harm in just moving them over to SFB, but I don't want to clog up my SFB environment with unnecessary data, and it would be nice to see what is in the Conference Directories. I don't even know what they contain. I think the reason I have two is because of a carry over from Lync 2010 which I am sure is not being used anymore.

这个问题还没有解决，但是确定了是因为电话没有获取证书导致无法登陆。

由于dhcp在a站点，通过网络设置让b站点拿到a站点的dhcp分发的ip，现在ip拿到了，但是电话机不正常下载证书。

请大家帮忙看看下面问题：

1.有什么方法检测到底是否是dchp server有问题？

目前a和b使用的都是同一台dhcp，请问有什么办法检测dhcp到底有没有问题？

2.”我建议可以检查下b站所用的DHCP scope配置。在b站网络中使用Test-CsPhoneBootstrap做下测试看看结果“，这个是之前的case工程师建议的方法，请问，这个test-csphonebootstrap命令是在B站随便的pc上运行吗？PS:b站没有任何SFB相关服务器。

3请问下面博客中的方法”web server method“是需要一台额外的机器做IIS服务器，还是在现有的随便一台sfb相关服务器上装iis这个角色就可以？

4如果真的手动导入证书，需要导入哪个证书，从哪下载证书呢？

SFB 2015. User migration hosted on SBA

Hi,

We have a OnPrem SFB 2015 environment in 1 Datacenter (FE Pool 1). We are in process of migrating servers to another DC managed by other vendor. Both DC has Firewall between them.

We are setting up new SFB Servers in target datacenter and will create new Front end Pool (FE Pool 2) in same Lync site.

There are couple of branch site where users are hosted on SBA and backup registrar pool is FEPool 1.

As part of migration process, we need to change the backup registrar pool of SBA in branch site to FE Pool 2. Could you please help me with the process?

As per my understanding, First I need to move all users from SBA Registrar pool to FE Pool 2, then change the Backup registrar pool of SBA in branch site  to FE Pool 2. Then move those users back to SBA Registrar pool.

Is there any way to change the backup registrar pool to FE Pool 2 without moving users or is there any other step which I missed?

Thanks

Lync 2013 - DNS Requirements - Best practices

Hello guys,

I actually deploy a test environment of Lync 2013. I've read a lot of post and I always have some questions about DNS requirements best practice.

Let's say my AD domain is test.local and my SIP domain company.com

I Set up a Split DNS zone on our Intenal DNS for company.com domain

In a Enterprise Edition Front End pools, when I Build the topology, should I use an A records for the pool and FE in the test.local or in company.com (according I create the pool and FE records in the split DNS zone).

I also made a mistake when I did my first set up. I configure the External web services in the topology with the pool FQDN.

I read that is not good but I can't understand what is the problem about it.

How to set up 2nd test pool with a test Oauth cert only for test FE pool servers?

February 24, 2019, 10:14 am
$

Hello,

The Topology Builder allows to set up more than one pools, I set up a test pool with its own file share and SQL DB connection. I requested its own certificate from the local CA like lync-test-pool1.domain.local . The issue is that the front end service is not starting. The Get-CsCertificate -Type OAuthTokenIssuer command gives back the productive URL, not thelync-test-pool1.domain.local, so I assume this is the problem. As the OAuch certificate is Global and replicated by the CMS, there is no way to use different OAuth certs in a global config? So if I want a test SfB environment I need to start my own CMS, so set up a completely new SfB environment? I would like to just assign the test pool to some user account within the Control Panel to test our Skype Update features, as I have this Skype for Outlook Meeting add-on issue, on a test account works, on a productive long used user account does not work, throws the sign in to Skype message also on a fully Patched O365 Client. I do not want to mess with the productive FEs, if this is possible.

Thanks in advance!

The Skype for Business Server Front-End service terminated with the following service-specific error:
%%3287185656

Start-CsWindowsService : Service RTCSRV failed to start. Check to make sure
the service is not disabled. Failure to start could also be because this front
end was previously failed over(using computer fail over), in which case please
invoke fail back(using computer failback). Consult event logs for further
details.

Office Web Apps Server IIS site disappeared?

I deployed an Office Web Apps server on a dedicated VM to be used for Lync 2013. After the initial installation / set up, I confirmed the discovery URL. It worked fine.

However, after one point in time, PowerPoint Presentations stopped working. When trying to share a PPT presentation, the Lync client popped up a message saying "Sorry, we couldn't upload <ppt file name> because we're having trouble connecting to the service. If this keeps happening, try contacting your support team". I've done many many Lync and Office Web Apps install myself previously, and never had a message pop up like the one I saw in this case.

I tried going to the Web Apps discovery URL again, and it didn't get anywhere. I got on the Web Apps server and all the IIS sites were wiped.

I tried uninstalling the Office Web Apps server and reinstalling, but from that point on, IIS sites for Web Apps just would not appear under IIS manager.

Has anyone had similar issue with Office Web Apps?

Thanks,

Can't Sign in to Lync - Event ID 3197,3198,18264,3014

Environment:

Lync 2013 on Server 2012 R2 Virtualized in Vmware.

Randomly out of the blue everyone would get "Can't sign in to Lync - Please sign out at another location and try again. You have reached the maximum number of computers or devices allowed."

Every time this happens in the event viewer Application logs I get the event ID's located in the Title.

These events happen once a day, every day.

There are no warning, or critical messages. I'm not sure what the correlation is between people being signed out and these events taking place if the databases get successfully backed up.

Input is greatly appreciated.

A little uncertain on the complete process for renewing the external certificate on the Reverse Proxy for our Lync 2013 environment. I cannot find any good documentation or posts on the process for renewing the certificate.

What I know:

Request the new certificate from the Public CA.

Import into the local machines certificate store.

Edit the binding for 443 selecting the new certificate.

What I don't know:

Do I need to restart any website or service?

Do I remove or revoke old certificates or leave them be?

Am I missing any steps.

Thank you for your help.

Music On Hold not working -PSTN Calls

March 22, 2019, 5:10 pm

Hi all

Environment Lync 2013, full patched and updated

Direct SIP trunk, no Gateway device provided by SIP provider

MOH doesn't seem to work no matter what.. i have tried a few things so far with no luck. P2P it works but fails on pstn calls. I have tried the following

-new client policy with music enabled

-different music files, now using defaulthold.wma that comes with lync installation

-clients can play the file manually so no permissions, file access issue

-confirmed that correct client policy is applied to lync clients

observation- every other pstn call, i can hear it tries to play music for a half second when caller is placed on hold and then on off hold, but in between no music, which makes caller think call is disconnected. SIP provider cannot enable MOH on their end and after talking to them, they say that lync is not sending them any packets during hold event, so there is no music played. I did capture the call and we looked at with them, in short a=inactive shows up when call is placed on hold which basically means no data is sent. On the trunk configuration side, i have set RTCP active calls and RTCP calls on hold to false and session timer true

questions..

1.has anyone experience this recently, any bugs in the latest CU in server 2013

2.what else should i check on the lync server side

3.if there is no media gateway device in between mediation and sip trunk, like audiocodes or similar, is there any other setting to change to force MOH

any advice is greatly appreciated
