Zelius,

у нас сервисы работают без вопросов. правда логгирование я сам делал.

WaitHint, единственное, увеличил:

Specifies the estimated time, in milliseconds, between a call from the Windows Service Control Manager and the service reporting its status.

WaitHint specifies the amount of time, in milliseconds, that can elapse between a pending start, stop, pause, or continue operation and the service setting its status with a call to the Windows API. Normally this is handled automatically. If the service performs a lengthy operation of more than WaitHint time in one of its event handlers, you should call ReportStatus method to update to the Service Control Manager.
