Yes the path is C:\Program Files (x86)\In-Synch\RMSDBSyncService.exe.
I set up a File System Shield exclusion for C:\Program Files (x86)\In-Synch\* so it stopped deleting the executable.
It's not disabling the service constantly, just every now and then. I haven't found a pattern yet. I spoke to the software vendor and they've noticed it on other networks. Apparently if you re-enable it several times it eventually stops disabling it.
