My client machine is connected with core switch->firewall-core router-ISP.
Please some one suggest what could be the issue.
Thanks SIva

Have you defined any port ranges Get-CsConferencingConfiguration
is the set ClientMediaPortRangeEnabled : False
Can you provide the Uccapi logs showing the invite sent for desktop sharing and the 200 ok response along with the BYE so that we what going wrong

Lync Desktop sharing fails in Citrix users for peer to peer session

Hello,
We have Lync 2013 servers and we have some user having citrix session and using lync. When users is citrix try to share the desktop with normal desktop lync client users , error message says connection not established.
when checkng the logs of citrix users..it says
ms-client-diagnostics: 52164; reason="Appsharing session disconnected due to RDP stack closed the connection";CalleeMediaDebug="application-sharing:ICEWarn=0x0,LocalSite=172.24.41.128:65494,LocalMR=194.187.115.31:50760,RemoteSite=10.1.106.214:65493
Citrix to Citrix sessions working fine, and Nomal desktop lync client users does not have any issues.
Any one can help?

It is a network issue.
The RDP stack block the traffic of Lync application session.
The port 1024-65535 for client is required to be opened for application sharing.

Things which can break Lync desktop sharing

Proxy URL filter
For one of my customers, Lync desktop sharing suddenly stopped working only from a particular network. All required ports were opened, telnet , tracert all fine, also sometimes we saw it working , so it was intermittent. you can guess what security
and network team will say J.
Then captured traffic in netmon and it shows that there is reset for 443 traffic and uccplog shows error which points to 443 inspection device on the network , so shared it with network and security team, you wouldn’t guess their response this time
J they asked me to identify the device which is resetting 443 session. Now I only had to solve this issue, I knew even PSS engineer can only tell us that there is reset.
I started off with question How it works some times?” , answer to this is that whenever it worked someone from Local IT team has logged in to that computer, also when logged in as normal users netstat shows time wait for 443 and sometimes sharing invitation
expires. This gave me a clue, so I asked for a new laptop which is not a member of any domain and started drilling down. ..Finally found that URL filtering rule has been applied to users in that subnet and corp application FQDNs are not bypassed. It
was URL filtering application which was stopping this traffic.
I told security team that proxy is causing this issue GUESS WHAT they asked me why they were not informed about Lync FQDN earlier
J
WAN optimizer.
It was another lovely day in office talking all important topics like work life balance, movies , next best weekend place etc… suddenly tickets started flowing for desktop sharing issue. Immediately P1 case was opened and all of us specialist joined P1 bridge
just to say WE DID NOT DO ANY CHANGES! Now someone is surely jealous of someone being happy or someone has not followed the change process. Who it is? And what it is has to be investigated, of course by Lync team.
Again netmon says 443 rest and error message says 443 inspection.. Being a Microsoft application expert you are not done yet without finding out which device is doing it, isn’t it? . So started isolating the issue. Noticed that issue is happening
only from specific region only. So asked everyone on call what is so special about this region…there was a dead silence and there was a smart answer YOU TELL US! Well this went on for a while till someone from network team asked with low tone
will wan optimizer has any impact on Lync traffic??
J
It was WAN optimizer which was causing this issue.

How Lync desktop sharing works for internal users

Hi,
How Lync desktop sharing, Aplication sharing & A/v conferencing works Internally ?
is it uses Webconfrencing Edge server & A/V Conf Edge server for internal users also...
I have confusion on this please help me and guide me how to deploy internally.
does it works with edge server internally if yes how ?
Thanks !!!

No internal to internal conferencing, A\V and desktop share does not use the Edge Server. This is all handled by the Front End Server\s.
For assistance on deploying please refer to http://gallery.technet.microsoft.com/Lync-Server-2012-9d6fe954

Lync Desktop Sharing pausing for actions an administrator needs to accept

When using Lync desktop sharing on a user that is a local administrator on their computer, the lync desktop sharing session pauses each time I try and execute a program or go into the registry? UAC is active on the users computer and we are not going to
turn this off for security reasons. We have used other products like Cisco WebEx, Citrix Desktop Sharing, LogMeIn, etc... and they don't have a problem with the UAC prompts, only lync is having these issues. Is there a patch or a setting
somewhere to allow these evelated privilages for a lync desktop sharing session?

I'm visiting these threads because I also would like to use Lync to assist my end users within a screen sharing session.
Let's say my Sales VP has an issue, and uses Lync to contact me.. we start a screen sharing session, and I see how I can fix it... but as soon as admin permissions are needed, we're stuck... I can't see or type my admin creds, and I'm not going to tell him
to type mine in.. so I either have to switch to LogMeIn, RDSH into his machine (more disruptive) or hike over to his office, (where our offices are on a 90 Acre park...if he's even on-site)
It would be most excellent if named users could be assigned permissions within 365 so that they could perform help desk tasks, where Lync recognizes admin credentials and allows administrative tasks to be performed on the host.
Bringing this feature to Lync would be a real benefit.
I would love to ditch LogMeIn as their business model is changing, and anyway, they're not free.
So what are the technical or security challenges here?
best regards.

External clients desktop sharing fails

After reading through various articles and forum posts I am desperate enough to contribute my first post...
The Problem:
We have successfully implemented a Lync 2010 infrastructure.
Internal to Internal works perfect
Internal to external (or vice versa) works perfect except for desktop sharing (Audio /Video works perfect)
(with external being an internal user in an external network)
I tried to narrow down the problem and found the following issues:
23; reason="Call failed to establish due to a media connectivity failure when one endpoint is internal and the other is remote";CallerMediaDebug="application-sharing:ICEWarn=0x800029,LocalSite=192.168.18.105:5388,LocalMR=xxx.xxx.xxx.xxx:3478(public

So basically a client connects from behind a NAT device to the external IP of the edge av interface and the internal client tries to connect to the same external ip?
Is that meant to be that way?
Second issue (or same issue but different perspective) same scenario(but network Sniffer on the firewall):
request reaches FW:
50.436292 port2 in Guest IP:35962 -> external AV Edge IP:59676: syn 2844552579
request routed through FW to the internal DMZ IP:
50.436857 Lync-extern out Guest IP:35962 -> 172.16.13.204:59676: syn 2844552579
session gets resetted:
50.437046 Lync-extern in 172.16.13.204:59676 -> Guest IP:35962: rst 0 ack 2844552580
This repeats very often till both clients get a notice about "Network issuses.
On the Edge Server I did an netstat -oa and found Port 59676 to be listening (TCP)
I read so much in the last days that I am totally confused by now and I think the documentation on tech net is faulty somehow.
(at least regarding port 50.000 ->59.999)
Maybe the issue is DNS related (we got split DNS in place)?
Any thoughts helping me out would be appreciated!
Thanks Gunni
Who needs a signature?

Hello Gunni,
please can you tell what is the vendor, model and firmware of your firewall? Are there any kind of "deep inspection" features enabled in the configuration of the firewall.
I am asking, as we have seen similar issues with an RST that seemed to come from the Lync Edge Server, but in fact the connection reset was done by the firewall. In the mentioned case the firewall is a Juniper, model SSG-5.
Two flow related settings activated in the configuration caused the issue, leading exactly to the ms-client-diagnostic: reason="Call failed to establish due to a media connectivity failure when one endpoint is internal and the other is remote"
“flow tcp-seq-check” - (TCP Sequence Check)
“flow tcp-syn-check” - (TCP SYNCRO Check)
Please check if your firewall has some similar or identical settings activated!
A lot of time, we investigated the Edge Server for any issues, - we even replaced it with a new one built from the scratch. Nothing helped, till we start looking closer at the firewall and disabled the settings mentioned above. I remember that we thought
the RST comes from the Lync Edge on the first look in NetworkMonitor and Wireshark. But when we started watching the Juniper reports, and comparing the time-stamps we realized that the connection was closed first by the firewall, not the Lync Server.
If your firewall offers a reporting feature (via webinterface, or SNMP, etc.) I recommend you to take a close look to check if the connection is closed here first.
Thanks and greetings from Berlin,

Control Lync desktop sharing between different subnets

Hi all..I want to control desktop sharing between differnet network.You consider this as we have multiple process.So desktop sharing should not work between other federated partners.
I have federation with xxxx.com for one xxxsubnet
another federation with yyyy.com for different yyysubnet
if i allow ports for desktop sharing with federated partner from both the network between theses partners all users can do desktop share.
But i neeed a solution like xxx subnet can share desktop only with xxx.com and yyy can share desktop with yyyy.com

Hi,
The feature is not available at present. But you can try to use lync Server SDK to customize this feature.

Discoverer Desktop Connections Fails With Invalid Username/Pass in r12

Hi all;
I have problem. I can login Discoverer Administrator from my localmachine and i can see what ppl did it there.. But when i try to login Discoverer Desktop from my localmachine its gives me Invalid Username/Pass. error.
I even cant login my system from browser :
http://xx.com:7778/discoverer/plus << pages comes and i fill in the blanks area like:
Connect to : Oracle Application
Username: sysadmin
pass: ***
Database: VIS
I found some document from forums. Whihc is :
Discoverer Is Unable to Connect to Oracle Applications database: invalid username/password Doc ID: Note:467919.1
Discoverer 10g (10.1.2) Connectons To Oracle E-Business Suite 12 Fails With 'Invalid Username/Password' Doc ID: Note:443661.1
But before i apply those patch i want to take advice from you. Coz i can login Discoverer Administrator and can use it but cant login Discoverer Desktop...its kind of wierd... i already checked what i have done in installtion and its all seems correct.
Any idea;
Regards
Helios

Discoverer supports two kinds of connections - database schema connections and apps connections. For Disco Admin, you login using a database schema, which, as you stated, works. For Disco User you login using an Apps user account (for which there is a no equivalent database scherma). To enable such a connection, you need to check the "oracle applications user" check box on the 10g Disco login screen. Also, under Tools --> Options, in the Connection tab, make sure that "connect to both standard and applications EULs" radio button is selected.

Powerpoint web sharing fails with "some presenting features are unavailable due to server connectivity issues"

Hi,
I am having problems getting PowerPoint sharing working with Lync 2013. My setup is as follows
Lync 2013 Enterprise pool (november 2013 updates) on Windows 2012 and
Windows 2012 webapp farm
Kemp HLB
Everything is working ok, including whiteboards and application sharing, but i cannot get the powerpoint sharing to work. I always get the "some presenting features are unavailable due to server connectivity issues" for internal or external
users.
The webapp looks healthy and there are no errors in the Lync server or the webapp event log. Discovery urls can be accessed and i have put the .net 3.5 as suggested in a few forums.
When a user starts the PowerPoint it successfully loads the file to the Lync file share and request goto the webapp server. I am using a HLB which shows me that requests are forwarded to the webapp farm. I have removed the HLB for testing and get the same
results.
I did log this with the forum a month or so ago, but I had a file upload issue then which is now solved, but the powerpoint sharing is not.
any ideas?
sg

I ran some diags on the client and i managed to find an error. This was in the client debug logs when trying to start a powerpoint presentation
54019;reason="The presentation at the WAC URL does not exist.";ClientType=Lync;Build=15.0.4551.1007
The url in the next line shows the paths which have the correct toplevel URLS (have changed the domain name in the pasted text)

Re-installation of Met Office Desktop Widget fails with the "installation file is damaged" message

However many times I re download the widget app I get the same result.
The reason for the download was that the previous installation started to behave strangely downloading a lot of stuff for no apparent reason. I have Kaspersky Internet Security which is up to date and Advanced System Care. None of my security programs report any malware.
Re-installation of windows is out of the question!!!
I have tried everything on the forum with no sucess - any help gratefully recieved. Thanks

I have EXACTLY the same issue, had issues with downloading excessive data. Uninstalled latest version of widget and latest version of Adobe Air. The I reinstalled them fresh...or tried too. The Met Office Widget failed exactly as yours did. My log looks like yours.
I contacted the Met Office and got this response:
Thank you for your email.
There is a known issue at this time with the Met Office Desktop Widget which is currently under investigation by our IT Team.
We hope to have this resolved shortly and we apologise for any inconvenience this may have caused you.
We just might have to wait they have no date for a fix yet!

Lync Desktop sharing is not working via Remote Access Server / VPN

Sometimes, few users using RAS (Remote Access Server) / VPN are not able to share desktop.
It is irrespective of other user (from other end) is using VPN or Office wired network.
Note - we have enabled VPN split tunnelling for our environment and the issue is happening after that only.
Also, it is happening with few users not all.
laptop is : HP elitebook 2570p
any resolution ?

Hi,
Did these issued users also meet the issue internal the corporation?
1. Please double check if the split tunnel VPN setting configure correctly with the help of the link below:
http://blogs.technet.com/b/nexthop/archive/2011/11/15/enabling-lync-media-to-bypass-a-vpn-tunnel.aspx
2. As the issue only happen for a few users who using VPN, please try to delete Lync user profile and then test again.
3. Please also try to change another computer with the issued Lync account using VPN to test the issue.
4. Please also try to test the issue with Internet network instead of VPN to test the issue again.
Best Regards,

Desktop Sharing Failure with one Federated Partner

Hi all,
We are running a single Lync 2013 FE and a single Lync 2013 Edge Server. We don't have a proxy server in the mix.
IM and presence works fine, but we are having issues with screenshare between us and all federated contacts in one domain.
Interestingly, while on VPN its fine, so it seems like its a firewall issue.
Following the
http://www.lync-solutions.com/Documents/Lync_2013_protocol_poster_v6_7.pdf I've had the firewall team open up all the required ports, but we still get errors when attempting a screen share stating that network problems are causing it to fail. Looking at
the topology builder, I see port 444 as the default port for the web conferencing Edge service, but I can't find any documentation indicating that this has to be opened up through the firewall.
Does it need to be opened from the internet to the IP of our access edge FQDN?
DQ

We've had the firewall support looking through the logs this past week, after replicating a screen share failure. They don't see any denies for traffic in between firewalls in the following traffic route I provided them.
Lync Federated traffic path: our client workstation -> our Lync (internal server) – IP -> our Lync Edge in DMZ
(internal facing NIC IP) -> (external facing NIC IP – public NAT
IP) –> And Out to the Federated Partner
When a screenshare is initiated, does the traffic still flow back and forth through the same (above) path, or could it be a different path (and trying to go directly to one of the Edge or Public (NAT)
IP for the screenshare service?
I'm wondering if it could be a routing issue. Because of our client requirements, network has some complicated routing in place, and maybe it's not heading out to the 'internet' or back from the internet
as it should be. Still no further ahead, but hopefully eliminating some possibilities.

Youtube sharing fails with correct passwords

Just wondering if the trial version does not allow youtube sharing. I have checked and double checked my youtube passwords, so I know they are correct, but FXPX returns with a fail and blames it on incorrect password/username.

There are many on this forum complaining about this issue. If you have not Compressor buy it. That is the way to go. Never fails.

When creating the desktop from a .portal file in the admin tools, the .portal file is parsed and validated before persisting to the database. It looks like this is failing and you are getting some fairly straight-forward messages. Check the format of the contents in the .portal file and make the necessary corrections.
