Problem : WSUS 3.0 Error 12012. The API Remoting Web Service is not working.

I have installed WSUS 3.0 on a Windows Server 2003 SBS but I am unable to connect to the administration MSC*.

I have the follow error in System Logs > Application.

Event Type:      Error
Event Source:      Windows Server Update Services
Event Category:      Web Services
Event ID:      12012
Date:            04/10/2007
Time:            14:02:30
User:            N/A
Computer:      ASYNTSERVER
Description:
The API Remoting Web Service is not working.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

I have used wsusutil checkhealth to make sure there are no other problems and this appears to be the only error I have.

I have uninstalled and reinstalled both version of the ASP .Net frame work (1.1 & 2.0) with no fix.

I started to follow the Microsoft Help & Support document regarding this error message, but when I was asked to compare 3 vbs files, Microsoft only listed partial parts of these files, making it impossible for me to tell if the vbs files are correct.

I have, however, checked the cacls on the WebServicesApiRemoting30 and can confirm these ACEs are correct.

I have reinstalled WSUS 3.0, but still no luck!

Any ideas?


 

Solution : WSUS 3.0 Error 12012. The API Remoting Web Service is not working.

Tried everything, my last resort was getting in contact with Microsoft Support (thankfully we are a partner so support was free !)

After 3 – 4 hours of them remotely trying to resolve the problem, it was a little tick box in IIS that eventually gave us the results.

I/You need to ensure that HTTP Keep Alive is ticked within IIS.

To do this…

Open IIS > right click WSUS Administration > click properties > on the Web Site tab under Connections tick Enable HTTP Keep-Alives.

Fixed the problem!!
