Windows service does not recognize network path. Whats the workaround?

We have a Buffalo NAS drive as a backup drive.

And when we map this drive as B:\ , our backup application seems to understand this and run as an application.

But when run as a service, it does not recognize the mapping and crashes.

I tried giving the path as \\\192.168.x.x\Backups\ as the backup path, the service runs but then a lot of submodules fail because it sees the \\\ as a escape character.

What is the workaround so that the windows service can see the mapped drive.

I am trying to run zip.exe via a CreateProcess();

""C:\Users\jvenkatraj\Documents\SQLite\Debug\zip.exe" -9 -q -g -u "\\\192.168.123.60\Backup\store\location1\50\f2\25\43\d8\88\b9\68\49\8d\2b\d0\08\9e\7e\df\z.zip" "\\\192.168.123.60\Backup\store\temp\SPD405.tmp\file_contents""

The backslashes are messing with the quotes. And it is a WCHAR type, and I can't change it to any other type, else I will have to redefine this elsewhere as well. How many backslashes should I use?

You can map a network drive inside the service itself using the WNetAddConnection2 API function.

The easiest way to do this would probably be to access the network path

string path = @"\\192.168.x.x\Backups\";

Another thing you have to make sure of is that the service has access to this path. If your service is logged in as a user that does NOT have access you have to change logon credentials of the service to a user/domain account that does have access to this path.

Try running your service under a user that "sees" the network, such as the "Network Service" user or even as the "human" user that mapped the network drive.

Create a symbolic link somewhere to the NAS share:

mklink /D c:\nas-backups \\192.168.x.x\Backups

and point your backup application to c:\nas-backups\etc.
