Unable to map a network drive

I am trying to map a network drive with an address like this:

It's basically a folder on the school network, I can access this folder and view its contents perfectly fine through an internet browser, but when I try to map a network drive to it, it doesn't work, I keep getting errors like this:

Quote:
A device attached to the system is not functioning
Why do I keep getting this message? And why am I able to access that folder through a browser but not through windows? I am using Windows 7 btw.

Any help much appreciated.

Netbeui and Windows 7

I am interested in this subject as my company supplies the CNC systems with Netbeui interface. It is possible to install XP netbeui on Windows 7 and tis appears to work Ok for direct PC to CNC connections using our PC interface, however wireless does not work and drive mapping is not possible.
If you share a disk on the CNC you can connect it on Windows XP, you can continue to connect it on Windows Vista but you can’t connect it anymore in Windows 7.
This is due to the fact that we used (and we do not have alternative choices) an old (today) Microsoft DOS disk server to share the disks on the CNC.
The protocol between that server and Windows 7 is not supported anymore by Microsoft itself because it is too old (please note that both software “sides” are from Microsoft so we can’t modify them).
We already asked them several times to make it work with Windows Vista but they always replied that it is too old and they do not support it anymore.
We are working on a solution that will allow connection using our WiNBI PC interface. In the meantime embedded XP looks like the best solution.

@emkay
When you open map options, can u browse thru the path and see the folder u r trying?

Basically, I dont provide the path myself, rather than browse and selecting it.

Hi there
The Browser can access the file via the URL - .

However when you need to map a network drive you need to know the REAL name of the Disk / folder or the Share name that is on the server.

If the DISK directory hasn't been marked shareable then you are out of luck.

The browser can access the folder since this will have been set up as a "page" you can access on the remote server -- the same way as you can access other Internet addresses.

The real foldername might be something like \\schoolcomputer\disk3\mainfolder\subfolder1 etc etc.

If it's a UNIX or Linux server then unless the file is shared via SMB protocol or similar you won't be able to address it from a Windows machine as a Disk drive or map it to a letter on your PC.

Cheers

Is it a Linux or Unix box you are trying to map to???

I discovered this while trying to get Windows 7 to map to shares on a Buffalo TeraStation (which uses Samba I believe). Win 7 has issues mapping drives on Linux/Unix boxes... this cures the issue!

You need to edit the Local Security Policy of any machine that you are going to map...
  1. Run the Local Security Policy App (secpol.msc), Start --> All Programs --> Administrative Tools --> Local Security Policy
  2. Go to Local Policies, Security Options and choose "Network Security: LAN Manager Authentication Level"
  3. Set it to "Send LM & NTLM, use NTMLv2 session if negotiated"
That's it... worked like a charm for me!

Thanks for the suggestion but it is not a Linux system but DOS 6.2! It uses Microsoft DOS networking

network Win 7 and XP by creating logical drives

I was able to fix a similar problem between XP Pro and 7 Home Premuim. Go to the 7 Start menu Search Box. Type in "\\PCName\" OR "\\IP Address\".

This brings up a list of shared drives and folders on the other PC. Write down the name of one you want to access. Then click it to find out if it is accessible. Some may be listed but not accessible.

Then open Windows Explorer, Right-Click on Computer, select Map Network Drive. Choose a drive letter and then type in the exactly same thing you did in the Start menu Search box. That will create a logical drive on the Win 7 PC that will be permanently accessible when you open Windows Explorer or any other program.

I also used Map Network Drive as above to create logical drives on the XP Pro PC to access the 7 PC. It was harder there, because I could not find a list of names and just had to guess.

I did it this way because XP and 7 could ping each other but could not otherwise "see" each other.

Thanks to aem for the idea.

Try changing these settings in Control Panel>Administrator Tools>Local Security Policy:

* Computer Configuration\Windows Settings\Security Settings\Local Policies\Security
Microsoft network client: Digitally sign communications (always): Disabled

* Computer Configuration\Windows Settings\Security Settings\Local Policies\Security
Network security: LAN Manager authentication level: Send LM & NTLM - use NTLMv2 session security if negotiated

Restart the system after making changes.
