I have a weird permission-related problem. My account is entered as a local administrator, just to be on the safe side.

If I want to retract or remove solutions within the CA I am getting either an Access Denied (remove) error or an Exception stating that only machine administrators can create SPJobDefinitions (retract).

The exception message for retracting has the following wording:

Access denied. Only machine administrators are allowed to create administration service job definitions of type: Microsoft.SharePoint.Administration.SPSolutionDeploymentJobDefinition, Microsoft.SharePoint, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c.

Unfortunatlely, there is nothing to be found in the logs for the above error, only for the Access Denied error when removing:

02/10/2015 11:02:38.14  w3wp.exe (0x10F0)   0x1F70  SharePoint Foundation   Topology    8u9s    Medium  Solution Deployment : Global solution mysolution.wsp, deployed to 0 servers. Deployment config object is null   48d45ec2-3ab6-4990-a6ae-4e59ae384ffd    
02/10/2015 11:02:38.14  w3wp.exe (0x10F0)   0x1F70  SharePoint Foundation   Runtime 6615    Critical    Access denied.  48d45ec2-3ab6-4990-a6ae-4e59ae384ffd    

If I just fire up Powershell and use the two appropriate commands:

Uninstall-SPSolution -Identity mySolution.wsp -allwebapplications
Remove-SPSolution -identity mySolution.wsp -force

Everything works. How is this possible?

  • Have you opened Central Admin window (Internet Explorer) as Administrator ("Run as administrator")? Feb 10, 2015 at 10:30
  • Yes Robert, sorry I forgot to mention this. I have tried it with IE and Chrome run explicitly as administrator.

I don't know what the reason for this was: but a simple reboot did the trick.
