IISARR URLS for Lync 2013 not working externally

Hello All,
Currently facing issue of opening lyncdiscover.domain.com from external.
I have created the server farm uing IISARR for Lync2013 & added 5 rules under the server farm as shown below:
meet.domain.com
dialin.domain.com
lyncdiscover.domain.com
owebapp.domain.com
When I tried browse all the above URL's none of the URLs are opening & showing below errors as attached screen shot:
Also when I tried test by using Lync 2013 Connectivity Analyzer showing below errors

Office Web Apps not working externally SharePoint 2013

In the production farm we have connected office web apps server which is FQDN server name ( xxx.xxx.corp.local) , we can open the sites internally without any issues, but when we open from externally office web apps asking for authentication and not working
properly.
Please help me how to make it work in external.
Thanks, Ram Ch

You will need a public facing URL or IP address. Check below
You need to configure your OWA for internet

Certificate Requirement for Lync 2013 Standard Edition

I have successfully run the setup of lync 2013 standard edition now I am stuck due to certificates required for lync 2013. when I generate a csr. it show the subjected urls for that.
hostname.domain.com
sip.domain.com
diali.domain.com
meet.domain.com
admin.domain.com
lyncdiscover.domain.com
lyncdiscoverinternal.domain.com
im.domain.com (External URL)
so if I go for 3 party CA then I need 8 certicate only for internal lync. As I also need to connected federated partner and external user so I need Edge for again I need 3 more certificates
web.domain.com
a/v.domain.com
sip.domain.com
now when I go for these certificate it quit costly and I didn't understand why such certifcates required. can anyone help me to fix such requirement.
Or, what are the necessary url to which I buy 3 party CA rest leave as it is.
I also want to deploy Edge with single adopter as we have only one network so can anyone assist me to proceed it further.
Talha Faraz Malik

To save on the cost of your third party certificates, I would deploy an internal certificate authority to sign certificates for your internal front end. For your third party certificate, you would only need the SANs for the edge and for your
reverse proxy and as Edwin said, this can be a single cert with multiple SANs.
For example, for your edge you would need:
sip.domain.com
web.domain.com
You would not need A/V as this role does not require a SAN on your certificate. On the same certificate, which you could also use on your reverse proxy, you'd likely want the following FQDNs.
lyncdiscover.domain.com
im.domain.com (your external web services FQDN)
meet.domain.com
dialin.domain.com
You may also want to consider your internal web services FQDN and include the following so third party mobile devices can connect without needing a certificate installed:
im_internal.domain.com (your internal web services FQDN)
lyncdiscoverinternal.domain.com
I'm sure that's not entirely clear yet, so feel free to ask more questions or what the purpose of each is.
When you say Edge with a single adapter, you mean a single adapter in a DMZ or internal? You definably want two NICS, both in separate DMZs, but I've managed to get the edge working with a single adapter in a DMZ before. What you don't want is
the edge in your internal network.

OWA 2013 watchdog system errors for Lync 2013 -

OWA Farm is configured on two 2012 servers. Lync 2013 installed on server 2012 as well.
I can access all services, internally and externally without issues on the client end.
However, my OWA farm machines are marked as Unhealthy per get-OfficeWebAppMachines.
The OWA Farm system Logs show multiple events related to source Office Web Apps Monitoring, event ID(s) 1004, 1010, 2004, & 2010.
What are the BroadcastServicesWatchdog_Wfe & AgentManagerWatchdog that are running, reporting these event codes, and where can it be managed?
The actual event codes
1004:
<?xml version="1.0" encoding="utf-16"?>
<HealthReport xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<HealthMessage>AgentManagerWatchdog reported status for AgentManagerWatchdog in category 'Recent Watchdog Reports'. Reported status: Machine health is Unhealthy</HealthMessage>

</HealthReport>

Yes, PPTs can be shared correctly; and the urls have been verified.
As to setting the http auth settings ~ this Farm isn't integrated with SharePoint, and is only in use for Lync 2013.
It is clear that these additional service executable , AgentManagerWatchdog, BroadcastServicesWatchdog, and BroadcastServicesWatchdog_Wfe
are from the OWA services to manage system health.
Where can they be configured, or worked with? They reiterate that
Reported
status: Contacting Participant.svc failed with an exception
Which leads to more alerts about the Unhealthy state of the machine. What is the "participant.svc" ?? that is cannot
contact? Is this internal to the OWA Farm, or is this a remote service connectivity check the Lync Front End servers?

DNS records to be created for Lync deployment (Internal and External)

Hi There,
If I want the Lync server environment to work Internal as well from External in all the aspects. (auto-discover, meetings, AV conferencing,web conferencing, voice integration, mobility etc), please answer to the below questions and also their purpose please.
I'm not sure whether the answer varies for 2010 and 2013 version.
1. What are the Internal and External(public) DNS records to be created for the reverse proxy(assume i'm using TMG servers), and their purpose?
2. What are the Internal and External(public) DNS records to be created for Lync Edge server, and their purpose?

I'll try to answer as well.
1) For the reverse proxy, you'll need to publish the following:
External:
lyncdiscover.sipdomain.com (You'll need this record for every sip domain you have). This is for client autodiscover.
external web services FQDN (You'll need one of these per pool, you get to choose the name). This is for address book downloads, web conferencing, etc.
Meet.sipdomain.com (You can choose the name here, and have one per sip domain or one for the whole org). This is for web conferencing.
Dialin.sipdomain.com (You'll just need one here, it doesn't have to be dialin). This is for changing your conferencing/phone pin, resetting conference info, and general conferencing info.
For Lync 2013 only, you may want the Office Web Application server pool name as well for PowerPoint sharing. Lync 2010 doesn't use this.
Internal:
The external web services FQDN. You'll need this available internally through the reverse proxy so you can redirect requests on port 443 to port 4443. This will be used for mobile devices on WiFi.
2) For the Edge server:
Externally:
sip.sipdomain.com (you'll need one per sip domain) this is an autodiscover/multi use FQDN and should point to your access edge IP.
webedge.sipdomain.com (edge web conferencing, you can pick any name you like).
avedge.sipdomain.com (av edge, you can pick any name you like).
accessedge.sipdomain.com (you'll need a name for the access edge role, however you can just use sip.sipdomain.com and save a name in your certificate request).
Internally:
edgepool.sipdomain.com (you can pick any name you want, it's just the name assigned to the internal edge interface.
If you choose to have a single ip for the external edge, you can get away with just an access edge name and/or sip.sipdomain.com

Setting up a Test Voice VLAN for Lync 2013

I want to set up a second voice vlan to be a test vlan.
In the current situation the customer has voice and data running on vlan1. The customer insist on taking incremental steps to improve QoS. I have advocated separated vlans for voice and data. They just want to move everything (phase 1) to a different
vlan. They want to see how getting all traffic of vlan 1 will improve there performance. Again, I recommended the best practice, they want to try this approach first.
I am conducting a pilot test with just one cx600 IP phone. and a single switchport. I created a new vlan99 using VTP. I configured the switchports on the Cisco 2960-x switch as follows.
#switchport mode access
#switchport access vlan 99
The phone gets its correct vlan id, and pulls its IP from the correct dhcp scope. However the phone displays "connecting with the lync server" for a long time, then "connecting to download its certificates". This takes a long time then fails.
If I change the switchport back to vlan1 it works fine. What can be the problem? Does the vlan99 need to be defined on the lync server? How many vlans can be supported by Lync 2013?
Thank you,
gigiu

Do we need License for Lync 2013 Edge server?

Hello Team,
We are currently running Lync 2013 Standard Edition Server. We are planning to enable users for External access and planning to deploly Lync 2013 edge server.
1. Do we need License for Lync 2013 Edge server?
2. Any other client licenses needed?
Please advise.

Hi,
No you don't required any additional License in order to install Lync Edge server. the only license required at OS level i mean windows server licence in terms of Lync concern you don't require any additional License
check this
https://products.office.com/en-us/lync/microsoft-lync-licensing-overview-lync-for-multiple-users
http://lyncuc.blogspot.in/2013/02/lync-2013-licensing-guide-how-to.html
And for client also you don't require any additional license with your existing client license will work for externally as well

SQL Cluster requiremnt for Lync 2013

Hi
We are are planning to deploy Lync 2013 enterprise. Planning to use SQL cluster. Would like to clarify whether we must create a sepearte sql instance for Lync 2013 or can we use an existing shared instance to create a seperate database for Lync.
We prefer 2nd approach. Is there any issues or demerits using existing shared SQL instances?
Thanks and regards,
Aboo Arif

Hi AbooArif.
This kind of question is very common. Basically here is the Microsoft Documentation about it.
Database software support in Lync Server 2013
https://technet.microsoft.com/en-us/library/gg398990.aspx
This point is the important: "If you collocate Lync Server databases with other databases, we highly recommend assessing all factors that might affect availability and performance, as well as ensuring that, if one node fails, the remaining node can
handle the load. To verify failover capabilities, we recommend testing all failover scenarios."
We can say the following: It's recommended to use a separate SQL server for Lync, however collating Lync database with other SQL databases will work, but has an high probability of present some performance problems. Many customers prefer to use this option
considering the cost of SQL licenses.
It is important to consider all the hardware requeriments for the Lync Server BackEnd role:
https://technet.microsoft.com/en-us/library/gg398835.aspx because the normal issue when customers share the SQL server with other instances is due to performance issues. Also note
that if you have multiple front end pools, these cannot share a SQL server.

OU For Lync 2013 Central Forest deployment when using GAL Sync

Hello,
We are attempting to set up Lync 2013 in a Central Forest configuration. We have a 2 way forest trust in place. The primary forest being A.com, the secondary forest being B.com. Exchange 2010 is deployed in both forests. Lync 2013 is deployed in forest A.com.
We currently have FIM 2010 installed, using GAL Sync between both forests. For GAL Sync, we have an OU in Forest A.com active directory called GALSync. There are currently contacts in that OU that correspond with the user accounts in forest b.com. Here's
my question:
When configuring FIM MA's for Lync 2013 Central Forest deployment, can I point the LCSCFG.xml file to the SAME GALSync OU we use for GAL Sync? Will it see the contacts already exist and just update with the necessary attributes needed to provision
the forest B.com users for Lync? Do I need to create a separate OU for the Lync MA to use? Or, am I going about this in the wrong way?
Any help you can provide will be greatly appreciated.
Thank you

Thanks for the reply Anthony
Almost right. The only difference is that the remote users will get the autodiscover url and the ews url from their local domain and dns.
Here is how it is setup:
Shared public namespace
mycompany.com (email address and sip address use this in both domains)
Central Forest (mycompany.com)
Lync 2013
Exchange 2013
Autodiscover url
autosdiscover.mycompany.com/autodiscover/autodiscover.xml
192.168.10.10
EWS Url
https://mail.mycompany.com/EWS/Exchange.asmx
192.168.10.11
Remote Forest (Fabrikam.com)
Lync 2010
Exchange 2010
Autodiscover url
autosdiscover.mycompany/autodiscover/autodiscover.xml
192.168.11.23
EWS Url
https://mail.mycompany.com/EWS/Exchange.asmx
192.168.11.24
User in Fabrikam login locally with their Fabrikam credentials. They have a Lync enabled contact in mycompany. There is a 2 way trust in place. They login to mycompany Lync fine.
When they do the autodiscover DNS lookup, they return the same autodiscover and EWS url, but they point to the local Exchange 2010 since their mailbox and user account still resides there and that is the system that the Fabrikam account has access to.
Autodiscover works fine for Outlook.
I will take a look at Fiddler

URL redirect over is not working..

Redirecting URL appended with querystring parameters for community is not working on SSO? We have SSO set up using Intergrated Windows Authetication.
When I launch new browser and request portal over SSO , works. Then I go to a community and copy the URL from browser. When I open new window and paste the URL extracting UserID from it, it gives me login screen and sso won't work.
If I do the same action twice in same window(for which I got the login screen firsttime), it works second time. How can I resolve this? Is anybody had this problem before?
Thanks!!

Physical cpu to virtual cpu ratio for LYNC 2013 FE

what
should be the physical cpu to virtual cpu ratio for LYNC 2013 FE and Edge server, it is same like exchange 1:1 ?

Putting this here as well:
I don't believe this is documented anywhere. I typically see 6 cores, but I've run with 4 or 8 but in the end it's all about watching performance.
System Center Advisory for Lync can complain if it's not at least 8.

Bandwidth required for Lync 2013 audio video call

Hi,
what is the required bandwidth required for lync 2013 audio video call from out side of company network. considering users will use owa integration with exchange 2013 for audio video call.
i tried with lync bandwidth calculator but could not figure it out.
actually i have some remote site where users have connectivity of 160 kbps only.

There are a number of variables such as call type and video resolution, but I would suggest using this table as a guide:

For example for capacity purposes with a Lync peer-to-peer call you're looking at 57Kbps (86 with FEC)
