You are using E-WMS 'Auto fulfillment', which means the E-WMS Fulfillment RF service is running, and the settings to allow for automatic validation and processing are enabled. The Exact Globe Next user setting 'Print preview' is disabled for the user account configured to run the service.
However, the delivery note is not printed automatically, and the service seems to be 'frozen' and does not read back new fulfillment lines.
The Exact Globe Next user setting to disable 'print preview' is saved in the file exactusr.ini. The default location of this file will depend on your operating system, this can be the folder C:\Documents and Settings\Default User\Application Data\Exact\Exact for Windows\4.0 (Windows 2003), or the folder C:\Users\(USERNAME)\AppData\Roaming\Exact\Exact for Windows\4.0 (Windows 7 and Windows 2008).
When an Exact (SDK) process (like fulfillment processing) is run from a Windows service, it turns out that the first location checked for the file Exactusr.ini is C:\Windows\SysWOW64\config\systemprofile\AppData\Roaming\Exact\Exact for Windows\4.0 (on a 64bit machine). When a user changes the 'print preview' setting in Exact Globe Next, this will be saved to the Exactusr.ini file in former mentioned location and not in the 'systemprofile' folder.
If for any reason (which is unclear at this time) an Exactusr.ini file exists at the 'systemprofile' location, the user settings are read from this file. In this file, the 'print preview' may still be switched on, and thus the service process applies a 'preview' for the delivery note. The service does not show the preview because it is a background process, but somehow still waits until the 'preview is closed'. This appears as if the service is frozen, but it just 'waiting'.
To solve this, you can manually copy the exactusr.ini file from the 'correct'
folder to the folder used by the service process. This would have to be done for
every (printer) change done in Exact Globe Next by this user. For this specific
problem, you could manually change the print preview setting in the file in the
'systemprofile' folder to 'off ('UsePreviewer=0').
