How to change the placeholder CONNECTIONSERVER_DIR

Hi, all

There is a corruption on our BOBJ 4.0 server. The DashboardServer is returning error:

The executable could not be launched. Possible reasons are insufficient RAM or disk space, or an invalid filepath or working directory. Actual reason: CreateProcess error=2, The system cannot find the file specified

I have already done a repair and it didn't help. When I look at the placeholder, somehow the placeholder CONNECTIONSERVER_DIR is pointing to a directory that doesn't exist. Can you advise how you can change that parameter? I just couldn't find a way to do it and no documentation is found either.

Thanks,

Jonathan.
