REST service API not exist or is inaccessible

Discussion created by sealjack on May 9, 2012
Hi, For some reason I got the following error when browse ArcGIS Service Directory (REST API) on web browser

"Service 'ProjectFolder/project1' of type 'MapServer' does not exist or is inaccessible."

Does anyone had this issue before and know how to fix it? I googled around and have tried logging to REST/Admin to clean the cache but it doesn't work. It worked after I reboot the server, but the problem comes back. Need help! Thanks in advance.
