What OS is this? do you see these services in the console and start from there? Check if there has been any virus attack on this machine. What is your BL Setup?
These files dont get deleted on their own.
were there any recent changes made on the box? a reboot?
Tried a reboot didn't work.
Tried to manually re-create the services using an old appsvc.exe and spawnsvc.exe.
Ended up - reinstalling the application and copied over the config from a backup.
All seems to be working fine just testing different situations now.
Thanks for the help and ideas.
