This is not a native windows file. It's a common program name and may be different file from different, possibly legit, vendors--but some are malware. Registry entry in HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Currentversion/Run for Name=DHCP and program C\WINNT\System32\Client.exe should be removed (IMO). Attempts to access internet on its own. ZoneAlarm detects and blocks attempt by MM2B_Client. Will generate error message "Runtime Error 10061 Connection is forcefully rejected." if it is blocked.

Best practices for resolving client issues

A clean and tidy computer is the key requirement for avoiding problems with client. 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 doing a repair of your installation, or in the case of Windows 8, 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 client.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. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
