When I try to run the upgrade solution command on my server I get following error:
The timer job for this operation has been created, but it will fail because the administrative service for this server is not enabled. If the timer job is scheduled to run at a later time, you can run the jobs all at once using
stsadm.exe -o execadmsvcjobs. To avoid this problem in the future, enable the Windows SharePoint Services administrative service, or run your operation through the
STSADM.execommand line utility.
