Network account keep losing access to network share folders on windows 7.

Lately, we started to get about couples of users each week unable to access any network drives on their laptop
We running widows server 2012 on windows 7 64bits.
If anyone who logged into faulty laptop no one can access any network drives. Can ping the server with no issue.
The only work around we found out so far is to un-installed All Network Adapter ISATAP under device manager click on View tab select show hidden devices and reboot . Screen shot attached
But after couple days it revert back to the same issue.

The permanent fixed is to re-image the laptop and not issue so far.

Could you please assist me on how to solve this issue without imaging the laptop?
Also I would like to understand what the symptoms and causing this issue.
And just to let you know – I’m a newbie with technology. So I’ll need the steps to be fairly simple

maybe there is a script we can run it remotely to fix the issue :)

Thank you so much for your help

This could be a potential IP address issue, Can you confirm that your internal network is configured correct:

- Server has a Static IP address
- DHCP Scope enabled with Reservation for Server address (of the address is outside of the Scope)

I also see the image shows VMware Virtual Ethernet Adaptor, have you a VMware test setup  that could be impacting the local network (is that image the Server or Laptop?) If you are running a VMware setup on a local Laptop that could also be causing an IP conflict and so more information on this could help.

Sorry did not mentioned this screen shot has been taking from my personal laptop sorry for the confusion.

I do not think I have access to the server but I will try tomorrow.

Could you please tell me what sort of information or trouble shooting detail would you like me to provide it to you.

On one or two test machines:

1. Run TCP/IP Reset and DNS Flush

Open cmd.exe with Run as Administrator
Then: netsh int ip reset c:\resetlog.txt
Then: ipconfig /flushdns
Then: restart the computer

2. Make sure you are mapping drives properly

Net Use Z: /Delete
Net Use Z:  \\server\folder  for all drives Z:

Do not browse for the network connection. Not a good method anymore.
Hi John,

I.have tried those command line in the past without any luck.

But I will try again on faulty laptop and advice with the outcome.

Do you know if there is any script or command line I can run and remove MS isatap adapter from device manager instead uninstall them manually.

Open cmd.exe .  

In the black command window, type:

Net Use  Z: \\servername\folder    ,  Enter

What numerical error do you get, if any?
