This is odd/unexpected. My guess is that the termination itself might not have completed and that BatchPatchRemoteAgent.exe is actually still running on the target. The reason I say this is because I can’t think of another reason why there would be an access problem all of a sudden. It seems like the Remote Agent is still sitting there and Windows has it open/running, so it can’t be overwritten. This is similar to the behavior that I would expect if you tried to delete an open Word document, for example. I would start by rebooting the target machine and see if that does the trick. Let me know how it goes.
I know you said other actions appear to work, but if that doesn’t fix it, could you please test “Services > List all services” and let me know if that also doesn’t work, and if so what is the error message?
Thanks,
Doug
