Wednesday, March 28, 2012 11:05 AMI have a lab of 30 computers, on just one of the pc's I have this strange problem, when any network user logs in the mapped drive appears fine but when they try and access the shared drive they get an error Location is not available.
Wednesday, March 28, 2012 11:12 AMIn addition, I would like to suggest the following:
Enable NetBIOS over TCP/IP:
1. Go to “Control Panel\Network and Internet\Network Connections”.
2. Right-Click on the connection and choose Properties.
3. Click “Internet Protocol (TCP/IP) Version 4” in the list.
4. Click Properties, and then click Advanced.
5. On the Advanced TCP/IP settings windows, go to “WINS” tab.
6. Under NetBIOS setting, click “Enable NetBIOS over TCP/IP”, and then click OK.
Face the fact tat we all have plenty to learn about this field. Deal wit the failures, use tem as motivation, learn something new everyday. Claiming false credentials & phantom skillsets will not get you far, especially when 63248651487512645876531864 people in the universe know how 2 use the internet

According to your description, I suggest to perform these tests to troubleshoot the issue:
First, please check whether the “Client For Microsoft Networks” is installed or not.
1.Open the Network Connections folder and view available connections
2.Right-click a connection, then click Properties.
3.On the Networking tab, in This component uses the following items, click Client for Microsoft Networks.
If not installed, use the install button and restart your PC.
If installed, please Temporally disable firewall and antivirus program to test the issue.
Then, Open gpedit.msc on this Windows 7 cilent, go to Local Policies | Security Options and choose the "Network Security: LAN Manager Authentican Level" item
Set it to "Send LM & NLTM, use NTMLv2 session if negotiated"
Meanwhile, you try to use Group Policy to remap this drive to test whether we can access the Mapped Network Share on this computer.
Using Group Policy Preferences to Map Drives Based on Group Membership
Hope it helps.

Thank you for your help!
Client for microsoft networks was already installed.
I have now set the Lan Manager Authentication level as you sudgested
I have also remapped the Network share, (\\servername\share1, I still have the same problem.
Just to recap, the other two mapped drives work fine (\\servername\share2, \\servername\share3)
The firewall and antivirus are disabled!
\\servername\share1 works fine on all other computers.
I could probably just re-image this computer to resolve it, but I have seen this problem once or twice before on other sites with Windows 7 computers so would like to know what has caused this issue and how to resolve it.

It seems this computer don’t have the NTFS permission of the \\servername\share1.
Please try to grant the computer Full Control NTFS permission on this share
For detail steps:
1.Right-click on that share
2.Click the Properties option,
then click the Security tab in the Properties window.
3.The Properties window
will now display those users (or groups of users) who have access to this
4.Click the Add button.
Ensure the “Computers” is in the object type and then add this computer.
Hope it helps.
