I'm using the SharePoint 2010 Health Analyzer and I've noticed that on some of the issues, when I open the Review window either or both of the Actions or Reanalyze Now options are grayed out. The pop up window says I may not have the right permission level to use this, might need to select an dobject or item, or the control might now work in this context. Can anyone explain why I wouldn't be able to do a reanalyze now? It seems strange this would be grayed out at all.
I know this issue is old but I was having the same problem.
Not only was the reanalyze greyed out but non of the scheduled tasks were running. I was able to trace it down to the account that was used to run "SharePoint 2010 Timer" service was not a local admin. I changed it to an account that is a domain service account that has local admin rights and had the rights outlined below:
1.Verify that the user account that is performing this procedure is a member of the Administrators group on the local computer.
2.Click Start, click Administrative Tools, and then click Services.
3.Right-click Windows SharePoint Services Timer V4, and then click Properties.
4.On the Log On tab, confirm that the account being used is a domain user account and is a member of the following:
dbcreator fixed SQL Server server role
securityadmin fixed SQL Server server role
db_owner fixed database role for all databases in the server farm
Here is the Microsoft link I used.
This resolved my issue. I hope this helps.
