As stated above, it is a process that is used by your modem, and is usesless but harmless if you don't use your modem. It can be disabled in msconfig.
It appeared after configuring my blackberry 8700 as a modem on my laptop. Although I also have a modem installed, this did not appear until I made the change.
idk, its slowing my computerdown, how do i remove it?
if u dont have dial-up u dont need it. delete it
came pre-installed on my laptop, it is a program to switch b/t internet dial-up connection and incoming voice calls. I just rt-clicked on it in my sys tray to exit, and took it out of my start-up menu. Hasn't bothered me since.

I had MoH v92, just run MSCONFIG.exe in your start menu\RUN look for LtMoH application in the start-up menu and remove the check mark. it will not start up again unless you re-check the box if ever you need to use a dial-up connection.

Best practices for resolving Ltmoh issues

A clean and tidy computer is the key requirement for avoiding problems with Ltmoh. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the Ltmoh.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
