Information

This article provides information about the command CMSTART.

Purpose of CMSTART command

Cmstart.exe is a process that runs when you log on to the XenApp server. It is called by winlogon. It is associated with Wfshell.exe, CltMgr.exe, and Icast.exe files. The cmstart is controlled by the following registry key:

Caution! Refer to the Disclaimer at the end of this article before using Registry Editor.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon Value of AppSetup

The purposes of cmstart command are:

  • Cmstart.exe starts the client manager file Cltmgr.exe (checks the client version upgrades if needed). It is possible that the ICA Client Update Database might be growing large. Disable the ICA Client Automatic Updates to see if the logon process is quicker.

  • Cmstart looks for applications under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce and HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce. If any executables are listed there, try removing them one at a time. Reboot the server after removing each executable.
  • Entries under HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon Value of AppSetup will override similar HKLM settings.

Note: By default, the AppSetup Value does not appear in this HKCU key.

Disclaimer

Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
