Endelig fandt jeg noget som ser rigtigt ud. På denne side:
http://www.data.net.uk/tcp_ip_faq.htmer denne tekst: (havde faktisk set den med ws2bakup.bat, men der var ikke en forklaring til)
Fatal Error! Cannot read IP configuration:
You may experience the following symptoms when you attempt to use a TCP/IP based utility or program:
When you attempt to use the winipcfg utility, you receive the following error message:
Fatal Error! Cannot read IP configuration.
When you attempt to ping a Web site name or TCP/IP address using the ping utility, you receive either of the following error messages:
Bad IP address <Web address>
PING: transmit failed, error code 10091
When you attempt to load a Web page using Internet Explorer, you receive the following error message:
Internet Explorer cannot open the Internet site <Web address>. A connection with the server could not be established.
When you try to uninstall Microsoft Personal Web Server 4.0, you receive the following error message:
WINSOCK2 is required to run this setup utility. Please click OK to exit setup.
To resolve this behavior, follow these steps:
Step 1 - Click Start, point to Programs, and then click MS-DOS Prompt.
Step 2 - At the command prompt, type the following commands, pressing ENTER after each command:
cd\windows\ws2bakup
ws2bakup.bat
exit
where windows is the folder in which Windows is installed. NOTE: If you are prompted to abort, retry, or fail the operation, press A. This causes the Ws2bakup.bat to continue restoring up all the necessary files. NOTE: If you receive sharing violation error messages when you run the Ws2bakup.bat file, continue with step 3.
Step 3 - Click Start, click Shut Down, click "Restart in MS-DOS mode," and then click OK.
Step 4 - Repeat step 2.
NOTE: If you receive error messages when you run the Ws2bakup.bat file stating that some programs cannot be run outside of Windows 95, disregard them.
In our experience, either one or other of the above will fix the most common TCP/IP errors, please also refer to Microsoft for other fixes, you can jump to the Microsoft Knowledge Base here.
