In the Windows environment, a job might not execute and exits with a code of 255. However, the job's command runs fine if you paste it into a Command Prompt window. This problem can be caused by two security issues:

• The permission for cmd.exe is set such that only an administrator can access it.
• The tmp location (for example, c:\lsf_6.0\tmp) does not have full control access for everyone

In the first case (permissions for cmd.exe), the installer normally adds Read/Execute permission to cmd.exe for local/User Groups. If that fails, then a warning message is issued during the installation.

To correct the problem:

1. Find the active cmd.exe file (Windows/System32/cmd.exe or WINNT/System32/cmd.exe).
2. Right-click and select Properties ► Security. The click Add.
3. Click Locations... and select the name of your local host machine. Click OK.
4. In the Object field, type users.
5. Click Check Names.
6. Click OK.
7. Click Apply.
