Thanks, guys, for your indulgence. I now have a batch file running that can run either IE or Edge and will execute the Javascript code using ahscript.dll and then kill the browser task. It seems clunky, but it works. Hopefully it will continue working for longer than the simpler ahcmd.exe. Time will tell. I appreciate your help.

@russ Had to create a shortcut, then give it elevated status and run the .lnk file from Triggercmd. Unfortunately also had to set user account control to its lowest level to avoid the prompt, “do you want to allow this program to make changes to your computer.”

@tuicemen For anyone still interested, the problem was the x10nets.exe service hanging at random. I never did find a version of x10nets.exe that didn't, so my convoluted workaround is to include a taskkill command at the beginning of each batch file that kills the service. It automatically restarts with a new process ID upon receiving the next command from the dll. This has a number of drawbacks, including requiring elevated status for the batch file and slowing the entire process slightly. Oh well. It works for now.

@newstuffoldstuff As I look at the installer more closely, the version of ActiveHome Pro I installed WAS 318, but apparently the x10net.dll that came with that version was 313. So I seem to be as up to date as I can get. There's not much else running on the machine where x10net.dll hangs, so I wonder whether it would be worth trying different compatibility modes again.

@tuicemen Didn't take long. This one hangs too. It's strange because it will be working and then a couple of hours later, after nothing else has taken place on the server, it's not working.

@tuicemen If you happen to come across a place to download it, I'll try it. Thanks.

@tuicemen Ok...found ActiveHome Pro installer and am now running v3.0.0.313 of x10net.dll. We'll see how that goes.

@tuicemen I've been doing that. I got it from the SDK installer, but it's clearly the earliest version. Have been looking for a newer one. Lots of dead links out there. I'll keep looking.

@tuicemen Well, damn. Same behavior with the dll as with the exe. Works for a while and then doesn't. The x10nets service hangs and can't be restarted, disabled or anything else. Only remedy is to reboot. Now I'm stuck again.

@tuicemen You read my mind. Clunky is ok for starters, but it’s not elegant enough.
