Windows server 2019 - Cannot install features

Question

I am getting below error while trying to add either WAS-NET-Environment or NET-HTTP-Activation features in windows server 2019. I have to install these features using powershell since I have to do it on number of servers? Any ideas?

Add-WindowsFeature : The request to add or remove features on the specified server failed.
Installation of one or more roles, role services, or features failed. Error: 0x800f0954

Answer 2

I mean to say that this server is configured to connect to a WSUS server to get updates. Server itself is not running WSUS role. My objective is to install .Net Framework feature on it without bypassing wsus server which is the workaround suggested in the link LimitlessTechnology-2700 shared.

Answer 4

Server is reinstalled but still I am seeing same error. WSUS server is configured on this server via GPO and this server can reach it. I can see patches can get installed. What could I do to install .Net framework 3.5 with wsus server configured?

Answer 5

Hello,

Thank you for your question.

f the error 0x800f0954 occurs installing optional Windows features, it may be because the system is unable to access the Windows Update server. This is especially true in case of domain-joined computers which is configured to downloads updates from a WSUS server. It could also be possible that your computer was once a part or a corporate or domain network and the group policy setting is still in place.
