Here is the general description of the error message:
sqlservr (2320) An attempt to open the file "C:\Windows\system32\LogFiles\Sum\Api.chk" for read / write access failed with system error 5 (0x00000005): "Access is denied. ". The open file operation will fail with error -1032 (0xfffffbf8).
I see it in the logs serveral times. The server was off-line this morning and after reboot I started seeing these errors. Any ideas
