I was doing SQL server 2012 installation for my lync server 2013 lab and I ran into this error "Error while enabling Windows feature: NetFx3, Error Code: -2146498298, Please try enabling Windows feature: NetFx3 from Windows management tool and then run setup again."












Started the server manager and tried to install the .Net Framework 3.5 with SP1 and it failed with error “Do you need to specify an alternate source path? One or more installation selections are missing source file on the destination”














Now the only choice I had was to install .Net Framework 3.5 was using Deployment Image Servicing and Management (DISM). For more information on DISM, refer to this article. I tried to install it using DISM by running the command dism /Online /Enable-Feature /FeatureName:NetFx3 /Source:D:\sources\sxs but it failed with below error.


As it say “Error itself has solution in it” indeed it had the solution. I just had to modify the command and run it with /all switch like this, dism /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:D:\sources\sxs and it will complete successfully, as you can see.
Note: Make sure you have Windows Server 2012 media in the drive before you run this command.


After this SQL Server 2012 installation completed like a charm :)

Continued my Lync Server 2013 installation and completed with Archiving and Monitoring server roles.

Cheers,

I came across with this error "Command execution failed: Error Constructing or Publishing Certificate" when requesting certificate from internal CA server for Lync server 2013 running on windows server 2012.


After digging into the issue and the error I found that I will have to restart the Active Directory Certificate Services on CA server. Looked into application log and found the event id 53.


























I checked and found that Active Directory Certificate Services service on CA server service is already running.
































Now I just had to restart Active Directory Certificate Services service. After restarting the service, request the certificates again from Lync server and it will complete successfully.
