Answer 1

This could be several things;
1. If there is a pending Windows Update you might need to restart to install the updates. In any case, a restart could help
2. Try to use ResetSRS Tool -
http://technet.microsoft.com/en-us/library/bb309637.aspx (SCOM 2007, but still applicable for SCOM 2012)
3. Check that the Reporting Service is running
www.coretech.dk - blog.coretech.dk
there isnt any updates that stay pending on the server.
and yes reporting service is running. but when i try to run resetsrs i have got the error message.
