This is caused by the scan engine running into a loop in a folder containing a junction point.

To solve this issue, add the following registry key:

1. Download and extract this scan engine file (VSAPI-KD-AMD64-9.720-1010.zip) to a temp folder.

   Verify the contents of the file:

   1. tmpreflt.sys
   2. tmxpflt.sys
   3. vsapint.sys
2. Stop the ServerProtect Normal Server service.
3. Back up the original scan engine file and replace it with the downloaded file.
4. Modify the registry:

   Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\tmxpflt\Parameters
   Key: BYJP(DWORD 32 bits)
   Value: 1

5. Reboot the operating system and reload the engine driver.
    

   The reboot is necessary. Otherwise the new engine won't be loaded and the registry modification will not take effect.
6. After the reboot, open the management console and check the engine version of the Normal Server that the engine has replaced.

   Make sure that the version is 9.720.1010.
