Log Name: Archive Manager
Source: Full Text Index Service

Description:
FullTextIndex.Service: Error Starting Attachment Worker

DEP (Data Execution Prevention) is preventing the Full Text Index Service from launching the FTIAttachmentWorker.exe child process.

On Windows 2008 (64 bit), it is not possible to add an executable on the DEP, under the System Properties, as it gives the following "This program must run with data execution protection (DEP) enabled. You cannot turn off DEP for this program".

As a workaround, you may enable DEP only for Operating System Components, including the Windows kernel and drivers.

1.) Open Command Prompt as an Administrator
2.) Type in "bcdedit.exe /set nx Optin" (without the quotes)
3.) Restart Server

To verify that the setting had taken into effect after the Server reboot

1.) Open Command Prompt as an Administrator
2.) Type in "bcdedit.exe /enum" (without the quotes)
3.) Check on the NX value under "windows Boot Loader", it should be "OptIn"
