Sorry - I realise this 'fix' is somewhat cryptic... Herewith some useful additional info:
I have found that when I install Norton Internet Security on a PC which is running a
customised network (e.g. static Primary/Secondary/Gateway IP Addresses), this network
configuration no longer works after the PC is re-started (as requested by the Norton
installation procedure). I then found that using the NETSH command to reset the WINSOCK
and TCPIP stacks to their default settings rectified the situation.
The NETSH (Network Shell) command is used to display or modify the configuration of
the network settings on a Windows-based PC.
To access the NETSH command, you have to initiate a 'Command Prompt' dialogue as follows:
Click on : Start
Click on : Run
Type in : CMD
Click on : OK
You can now enter various NETSH (and many other) commands via this Command Propmt dialogue...
The lines of text below can be copied and pasted into Notepad to create a script file which can
be re-used as required.
Alternatively, you can simply type in the lines which begins with netsh
___________________________________________________________
Rem ** The following command resets WINSOCK entries to installation defaults **
netsh winsock reset catalog
Rem ** The following command resets the TCP/IP stack to installation defaults **
netsh int ip reset reset.log
____________________________________________________________
After you have done this you should re-start your PC.
This will also re-start your Network with the newly reset settings.
