Connection Manager Custom Connection Service Does Not Start During Winlogon (818874)


The information in this article applies to:

  • Microsoft Windows XP Professional
  • Microsoft Windows XP Home Edition

SYMPTOMS

When you use Connection Manager to build a custom connection service that runs during the Winlogon process, the connection service may not start during Winlogon. However, if you start the same connection service from the desktop, the connection service does start.

CAUSE

This problem occurs if the full path of the custom connection service contains spaces. When Connection Manager starts a custom action from WinLogon, the path is passed to the CreateProcess function without double quotation marks around the path. Therefore, if the path contains spaces, the path is split into separate path arguments at each space.

For example, the following path

C:\Documents and Settings\Application Data\microsoft\network\connections\cm\myprofile\custom.exe

is split into the following four path arguments:

C:\Documents
and
Settings\Application
Data\microsoft\network\connections\cm\myprofile\custom.exe
