To all the SharePoint developers
Due to our least interest in Administration of SharePoint. The three R’s holds the key for making our head save from banging into the wall.
1. Recycle App pool: Needs to do more often then pressing f5 key for the browser.
2. Reset IIS: If Recycle doesn’t work as it suppose to do, restart the IIS.
3.Restart the machine: If the problem persist, and your server is behaving like a mad cow :), Restart the machine
Hopes that it will work in your case as well
