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.

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 paused when asking for a admin credential

Is there any solution from microsoft side for the above mentioned question?

Not at this time. It was reported that running Lync as administrator could help, but this hasn't been a reliable solution.
Edit: I just reran this to see what it looked like for me as a refresher. When Lync is run as administrator, the remote user can't click the UAC boxes that allow the program to run in administrative mode, however if I as the sharer of the desktop click
Yes, then the remote controlling person then seemed to have access. Again, it's not a great solution, this is by design, and not slated to be changed in Lync 2013.

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

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??

It was WAN optimizer which was causing this issue.

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.

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

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.

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.

Lync Application and Desktop Sharing - Restrict remote access/Telnet

I have a customer and they are paranoid about using Lync application/desktop sharing which could potentially enable remote users from getting into their internal IT systems. They are asking if we could restrict application/desktop sharing specifically
for appls with remote access capabilities (e.g. Telnet, etc.)? Anyone could share any information relating to this? Thanks!

We can’t do this with Lync Server natively. Maybe you want to vote idea at

Disbale Desktop Sharing in Jabber for Windows for single users

Hi,
is there possibility to administrative disabling the desktop sharing feature for selected users?
CUP and CUCM is 8.6. Jabber is 10.5. Use DesktopSharing via Chat without any phone or deskphone only.
Regards

I am referring to the new Screen Sharing way in Jabber 10.5 for screen sharing without having a video call running:
"In addition to the video screen share (BFCP) feature that is available to video-enabled clients when on a call, users can now screen share directly from an IM conversation when video share is not provisioned or available."

Hi Narmadha,
Your issue seems to be out of the scope of this forum. We only focus on issue about RDS/VDI deployment, management and operations. For development and API issue it is appropriate to ask in our MSDN Forum:

Will this version of XP Home work for Parallels Desktop 3.0 for Mac?

For Christmas, I received Parallels Desktop 3.0 for Mac because I need Windows XP for certain reasons. First, I have several neat programs that only run on DOS and second, I miss MS Paint (I hate Seashore or Piantbrush) and Finally, I like MS Movie Maker better then iMovie. When I opened it, I got furious because found out that XP Home doesn't come with it, so I must purchase it online. I really need XP Home with SP2, and not XP Pro. I looked in the manuel and it says I cannot use OEM copies, but I looked at another discussion that said OEM copies were OK. Now I'm very confused, so I decided to make this post hoping that I can get a good final answer. Here is another problem, I only have $100 to spend because I'm saving up for a bigger gift that has nothing to do with computers. I want to know which copy will work.
Copy No.1
http://cgi.ebay.com/NEW-Microsoft-Windows-XP-Home-Full-SP3-FREE-S-HW0QQitemZ330294685997QQcmdZViewItemQQptZUS_Software?hash=item330294685997&_trksi d=p3286.c0.m14&trkparms=72%3A570%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1309%7C301%3A1%7C293%3A1%7 C294%3A50
Copy No.2

Copy No.3

If you know a better copy under $100.00 that will be even more compatible with Parallels, tell me.
Thank You and I hope you can answer my questions.

You have an intel based mac. that is one particular Original Equiptment Manufacturer. Now, what parallels does is build a vitual machine inside your mac to make it OEM compatible inside the mac Operating System to make Windows XP Home to work within the mac environment. Once it is fully installed, you can use mac and windows XP home together at the same time. You can also install XP home in mac boot and use it separate from mac as well to do your work separate of being on mac ss well. carefully read the instructions and the key part again is putting in P.T, for it to work properly.

What port number for Desktop Sharing using in Lync Server 2013 and Lync Online

Dear All,
My environment using Lync Server 2013 and Lync online on Office 365. I don't want my user using Desktop Sharing feature. then I need to know what port number for Desktop Sharing using in Lync Server 2013 and Lync Online.
I will deny this port on personal firewall each client.
Thank you for your advise.

Hi,
I'm not sure you'd be able to do this with ports without impacting other application sharing features such as Q&A, Whiteboard, Poll etc - I'm pretty sure they all come under the same umbrella of ClientAppSharing.
Ordinarily you would create or modify your conferencing policy to restrict sharing to single programs only using a cmdlet similar to below;
Set-CsConferencingPolicy -Identity "Global" -EnableAppDesktopSharing SingleApplication
This would disable desktop sharing but enable users to continue sharing other single programs. If you want to remove that functionality too, then replace the 'SingleApplication' parameter with 'None'. Then users won't be able to share any programs either.
This is the correct way to do it as the icons will be greyed out for the users. Doing it your way, they would still be able to click them, and it would throw an error - this will lead to a lot more support calls and people assuming a service is broken.
I hope that helps some.
Kind regards
Ben

How to block file transfer and desktop sharing in Lync 2010 for Fedrated and Guest Users

Dear,
Can anybody guide me how to restrict desktop sharing and file transfer for federated and Anonymous logins in Lync 2010.
I have tried to apply this policy through “Conferencing Policy”, but this gets applied to all users including corporate users.
Please help in this.

Hi,
As my knowledge, the CsFileTransferFilterConfiguration and setting in confercing policy are used to block transfer file between users. So if the policy is applied to user, the user would not transfer file with anybody. Since all Federation and Guest
Users access thought the Access Edge service, here is a update that helps to enable the control of the file transfer through the Access Edge service.
http://support.microsoft.com/kb/2621840
The update helps to define the file transfer policy between users on the local area network and users that connect through the Access Edge server in a Microsoft Lync Server 2010 environment. It helps protect Microsoft Lync Server 2010 deployment against
the spread of the most common forms of viruses with minimal degradation to the user experience.

Kent Huang

[Lync 2013] - Desktop Sharing and taking control

Hello,
In Lync 2013 when someone shares his/her screen and I'm taking control of the shared screen I have the following problem:
Everything works fine when I'm in control with other person's desktop, however when the Lync IM/Sharing window looses focus and then the focus is regained by clicking on the shared desktop, all the input is frozen in the Lync IM window.
for example:
I take control of shared screen, do something on the shared desktop, then I open something on my own PC (the Lync window is loosing focus at this moment), then when I click on the shared screen inside Lync IM window to continue controlling the remote desktop
any input to the Lync window is "frozen".
There is some error sound comming everytime I click in the Lync IM window during this time - just as there was some invisible popup that is blocking interaction with parent window
to solve this I have to once again loose focus of Lync IM window and then regain it again.
This is on many machines (Windows 7 64bit / Windows 8.1 Preview 64bit) using Lync 2013 32bit with and without updates
I'm using multiple monitors, but it's the same on a single display - just open Lync IM/Sharing window in one half of the screen and open notepad on other half (don't minimize windows, just switch between them during sharing)
Best Regards

Hi Bartek,
Did the issue happen on Windows 7/8 32 bit using Lync 2013 32 bit?
Try Clean Boot to disable all non-Microsoft services and start Lync again:
How to Clean Boot:
http://support.microsoft.com/kb/929135
Since the OS is 64 bit, please remove Lync 2013 32 bit and install Lync 2013 client 64 bit and apply the latest update then test the issue again.
