SfB 2019 Install Help
Hey everyone! Happy Monday! I'm trying to install a handful of on-prem Skype for Business 2019 into a lab environment and I'm falling at the second hurdle when running 'Setup or Remove SfB Server Components'. I'm getting the error: 'Error 0x8007054b (The specified domain either does not exist or could not be contacted) setting launch conditions on DCOM layer during action SetDCOMSecurityEx. CustomAction CA_SetDCOMSecurity returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox) Error returned while installing Server.msi(Feature_Server, Feature_HealthAgent), code 1603. Error Message: A fatal error occurred during installation.' All of the servers are part of the same domain. I can log into the skype servers with a domain account, DNs all seems to be working, nltest commands seem to come back normal. Things that I've tried: - Adjusting the COM Security settings for launch and Activation Permission to include RTCUniversalServerAdmins and my admin account to allow local/remote launch, and local/remote activation - Setting a group policy to allow the group EVERYONE to make remote SAM calls (this seemed to have a broken a lot so reverted... I saw it on an MS forum that fixed it for someone) - Run the installer as admin, run it w/out admin - Put the server into a 'staging' area in AD with no policies applied. Fortunately this same error is happening on all servers, which implies that there is a policy, registry key or some permission that's getting in the way. Does anyone have any ideas of some other things that I can try? Thank you! Edit: I know Skype 2019 is old, I know I should be using something else. I'll be moving to Skype SE in Oct.
How to Remove Skype for Business
Skype for Business currently installs as a packaged product with Microsoft 365 Business Professional desktop apps. The installation does not install Teams as a part of the Microsoft 365 Business Professional desktop apps. Additionally, Skype for Business has its own installation which is separate from Microsoft 365 Business Professional desktop apps installation. Windows OS: 11 Pro w/ Windows updates. Issues: Users are unable to remove Skype for Business from their desktop by clicking “Uninstall” located on the Windows Start menu. Teams upgrade requires Skype for Business settings to be set manually via the Teams Admin Center. Using the PowerShell command: uninstall-package 'Microsoft Skype for Business MUI (English) 2016' to remove Skype for Business requires NuGet to be manually installed prior to performing a removal task or does not remove the application at all. The odd thing about this is that the system recognizes that a 2016 edition of Skype for Business exists. Note: Microsoft Word reads with the following version number: Microsoft 365 MSO (Version 2508 Build 16.0.19127.20082) 64-bit Granting and then revoking API permissions via Entra Admin center does not separate Skype for Business from the Microsoft 365 Business Professional installation. Uninstalling Microsoft 365 Business Professional desktop apps only removes the Skype for Business app temporarily until reinstallation occurs.

Hi everyone, I wonder if someone could help me. We‘re using Skype for business OnPrem 2019 and some of our customers complaining about joining meetings. Sometimes it takes several minutes to let you join a meeting. Have you ever experienced something like this delays? We can’t really see anything on the Skype for business server. Could it be related to the hardware itself for example drivers? Thanks in advance.Response Groups and Not Ringing a Person in the Group
We have have response groups set up for almost two years. Recently, I have started having reports that some people in the group do not get calls to the response group. I confirmed that the response group is set up as parallel routing method. I cannot get the call to go to their phone. I signed on a test phone in my office and the call never rings their phone. However, the other three people in that office their phones ring. I have tried removing and adding them back to the group. I have tried changing from informal to formal participation policy and it does not work. Currently, I have a group of four people in the group but one person calls to the response group does not work. Has anyone else had this issue or have any suggestions on what to check? We are hybrid set up. This is the second or third response group where I have had this issue. One other group, I ended up changing them to formal, had the people log into the response group, and they have been working fine ever since (about two months). This group is not working and I am not sure why. Any assistance would be appreciated. John

White screen if use local web client in S4B 2019
I would like that my users don't use MS CDN and use only local S4B web client . 1. I have a link for meeting https://meet.exchlab.ru/test01/5V854YXZ?sl=1 2. If I follow it I see white screen. 3. But this page a not really empty it has a html code. 4. If I set UseLocalWebConfig to $false, web client S4B is downloaded from MS CDN and works perfect, but I need local client, because not all of my internal users have access to Internet. Why I see white screen instead of normal web page?

Hello all, Issue with my LyncClient is that I have observed a 2/ 3 minutes delay in getting event for SkypeForBusiness SignedIn after restart from sleep/ hibernate. This issue is not observed on development machine but in customer environment. I read somewhere that these events are received from SFB server and the delay can be because server takes time to sync the events with the client. I am registering for the event using following code during app startup Client.StateChanged += new EventHandler<ClientStateChangedEventArgs>(Client_StateChanged); Any assistance will be helpful.
