PM'ed you the following as well
----------------------------------------------------------
Sorry, I never logged back in to see if someone was really interested.
Here is the link to the setup that will install it as a Windows Service called "Prevent Sleep".
http://www.4shared.com/file/ObQx4iUc/PS ... Sleep.htmlAfter you install it, go to: "C:\Program Files (x86)\SumitSoft\PreventSleep" and edit the PreventSleep.exe.config file. Under the IPAddressList key, add the IP address(es) of the devices that if running should prevent your PS3 Media Server computer from going to sleep.
This comes with non warranties and if someone really needs a source code, I can provide it too. It is a .Net application that requires .Net framework 2.0 that all windows machines should have.
Sorry again and hope this helps someone in need!
