The Terminal Server configuration utility (Tscfg.exe) and User manager (Usrmgr.exe) do not seem to correctly communicate configuration information concerning modem callbacks.
Callbacks can be set for each connection by TSCFG or for each user by USRMGR. TSCFG should take priority, or the setting can be set to inherit from "User config" by selecting the Inherit User Config option. However, the Inherit User Config option does not work and is ignored. In all cases TSCFG options take effect.
The problem is caused by Winlogon and not by the configuration utilities.
