writing a file to a network fileshare **SOLVED**

[Sgt-Peppa]

Hey all,
I am trying to write a file to remote Fileshare on the Network. I mapped the Share as NetworkDrive. Now I am writing the file as usual using

FileStream streamWriter = File.Create(filepath);
streamWriter.Write(data, 0, size);

This works on a local drive but not on the Network drive.
I checked the Permissions on the Network Drive and did set those to Everyone Full Control.
Any idea what I can try to make this work?

Thanks, Stephan
