Update SQL Server 2014 SP2 constantly fails on Skype for Business Server

Recently i had set up a new Skype for Business Deployment, with a Front-end (Standard Edition) and Anywhere365. After installing Skype for Business roles, Windows Update popped up with SQL Server 2014 Service Pack 2 (CU 1) (KB3178925). I tried to install the update using the Windows Update, but everytime i got the error code: 84B30002 When looking at the log files from SQL i did not found anything spectacular, the only strange message is “user has cancelled”

DNS configuration is preventing you from presenting content

It looks like the file is not automatically updating after DNS changes. Some users will get the following error: You can solve this by deleting the “EndpointConfiguratation.cache” file. Sign out of Skype for Business Click File Exit Open File Explorer Go to “C:/Users//AppData/Local/Microsoft/Office/16.0/Lync/sip_@sipdomain.com” Select File: EndpointConfiguratation.cache and delete it. Launch Skype for Business client and sign in. When you have a older version of Office running change the 16.

Skype for Business environment running with just one Public IP

For quite some time I’m running a home lab, first on a big server (HP Proliant DL360) and since beginning of this year I have a Intel Nuc, saves a lot of energy costs 😂 Domain Controller and CA on Windows 2016 Core Edition Skype for Business Front-End Server on Windows Server 2012r2 standard SQL 2014 std for monitoring and persistent chat on Windows Server 2016 Exchange 2016 on Windows Server 2016 Skype for Business Edge on Windows Server 2016 IIS ARR (Reverse Proxy) on Windows 2016 PBX on Windows Server 2016 This lab was great for testing purposes but the problem was always, no connection to the outside world with Skype because of the requirement for at least 2 external IP’s with the use of Skype for Business.

How to enable a Domain Admin for Skype for Business

Perhaps you have seen the error message below when trying to enable a Domain Admin (not recommended) in the Skype for Business control panel. Active Directory operation failed on “DC01.skypedev.nl”. You cannot retry this operation:_ “Insufficient access rights to perform the operation_00002098: SecErr: DSID-03150F93, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0__ “.You do not have the appropriate permissions to perform this operation in Active Directory. One_ possible cause is that the Lync Server Control Panel and Remote Windows PowerShell cannot modify_ users who belong to protected scurity groups (for example, the Domain Admins group).
