Cannot Map Network Drive to NAS

Hello everyone, i am having some issues mapping a network drive to a remote NAS drive, first of all machines are win7 x64 and NAS is a D-Link DNS 320
NAS unit is at my office and all computers can map drive through wired network using internal IP address, all machines have Z: drive showing which prompts for password then access is granted

I wish to connect to this drive from my home machine but i cannot figure it out, there is a static IP address in place and i can access drive via web browser using this static address ie ftp://86.xxx.xxx.223 browser will connect, ask for user & password then grant access, but i cannot map it as a drive which i need to

I am trying to map \\86.xxx.xxx.223\Volume_1 to access the whole drive not sub folders but if poss would actually like to have seperate mapped drives to access sub folders individually but thats a side note mapping anything would be great

When i enter this i get

If i click troubleshoot i get

Do i need to add user into map address ? when navigating manually it adds Paul@86.xxx.xxx.223

Hi Pauly,

I'm not sure if this is the same issue, but please see this short thread I started a few years ago - the solution is my post #5.

Problem : automatically reconnect mapped drives at login

Funny enough i was reading this earlier today in a last ditch effort to sort before starting a thread, but my problem is not (re)connecting at logon its connecting at all!, i know the IP is right as i can ftp in through browser but cannot save as drive which means when saving file in a program for example i cant send it straight to NAS i have to save to desktop FTP & log on to NAS then transfer file, its so annoying i been doing this for 6 months and enoughs enough my keyboard is gonna have a fist hole in it soon

Well i have tried every combination i can think of to include/exclude user names etc still no joy

I just have a few stand alone machines all connected to a wired switch along with NAS box
