This week I had a migration where there was no high speed internet available, and the customer was renewing the computers from Windows 7 to Windows 10.

Due to these slow internet speed, we decided to install a WSUS server (server 2012 R2 based)

After the installation, the server didn’t finish the post installation tasks, and the server showed an error wile opening the WSUS console.

Error:

Post installation Tasks

Error:

Fatal Error: Failed to start and configure the WSUS service.

WSUS console error

Error:

An error occurred trying to connect the WSUS server. This error can happen for a number of reasons. Check connectivity with the server. Please contact your network administrator if the problem persists.

Solution

Go to IIS => select WSUS Administration => Remove this Web Site

Try to execute the post deployment configuration again

The post deployment configuration now works fine.

WSUS now works fine.
