Re: [Wrapper-user] Mapping network drive issue..

[Leif M. <le...@ta...>]

Anil,
You aren't going to like my answer.  Windows places restrictions on what 
a service is
allowed to do.   By default, the wrapper runs using a SYSTEM user.  This 
user is fairly
powerful within the current machine.  But it is not allowed to access 
network files or
printers.  It is however, allowed to become interactive and thus access 
the desktop.
http://wrapper.tanukisoftware.org/doc/english/prop-ntservice-interactive.html

In order to be able to access the network as a service, you need to 
configure a
specific account to run the service as.   That account is set up to be 
able to access
the network devices you want to access before the service is started.
http://wrapper.tanukisoftware.org/doc/english/prop-ntservice-account.html
http://wrapper.tanukisoftware.org/doc/english/prop-ntservice-password.html

Unfortunately, if you have configured a non-SYSTEM account to run the 
service
as, it is no longer possible for your service to interact with the 
desktop.  This
means that your service is able to access network drives OR display a GUI,
but not both.

This is a restriction placed on the service API by the Windows OS.  It 
doesn't
make a whole lot of sense why the interactive feature would be disabled.  At
least not if the logged in user is the same as the service user.  I have 
not yet
figured out a way to work around this other than to break out the network or
GUI features into a second service and then run them both.

Most non-java services seem to handle this by having a service which is 
installed
and always running.  Then they register another non-service application 
to start
when a user logs in.  This second app creates a tray icon and or 
displays the GUI
while the service does much of the work behind the scenes.

If you or anyone else has any other ideas on how to solve this, it would be
a great improvement.  Also if you have examples of other services where 
this is
possible, it may give me hints on how to get working.  As far as I know 
though,
it isn't possible.

Cheers,
Leif
