System error 67

[paul]

We seem to be getting the above error appearing on quite a few client PC's, which is causing no end of problems as its relating to the workstation service not running, if you restart the service all is ok but this seems to keep reoccurring. The following MS KB matches my symptoms perfectly but the remedy does not:

SYMPTOMS
If you try to log on to a computer by using your domain account, the domain controller stops responding. Additionally, you cannot access your folder by using the universal naming convention (UNC) network path, and you receive the following error message:
System error 67 has occurred. The network name cannot be found

CAUSE
This issue occurs if one of the following conditions is true:• The network components on the domain controller are not configured correctly.
• You did not update the network drivers on the domain controller or the drivers do not work with Microsoft Windows Server 2003.

Method 1
Update the network adaptor driver on the domain controller.

Note Make sure that you use a network adaptor driver that works with the operating system that you are using.

Method 2
If Network Address Translator (NAT) is installed but is not configured correctly, disable the Internet Protocol (IP) NAT driver, and then restart the computer. To do this, follow these steps: 1. Click Start, right-click My Computer, and then click Properties.
2. On the Hardware tab, click Device Manager.
3. On the View menu, click Show hidden devices.
4. Expand Non-Plug and Play Drivers, right-click IP Network Address Translator, and then click Disable.
5. Click Yes two times to restart the computer.

Anyone experienced similar?
