What you have described is a great example of why everyone should enable wireless encryption on their networks.
You started on the right track by changing the workgroup name because everyone's workgroup starts as mshome, so unless you change it you're inviting everyone else to be a member of your workgroup.
You have two PCs with wireless cards (NICs) in them?
There is no wireless router or access point involved?
Turn off Zone Alarm while you do the following.
You need to define a name for your wireless network - called the SSID.
I think you have to manually enter the SSID on both NICs and, if asked choose the Ad-Hoc networking.
Your network will then be a bit more exclusive but anyone who "sees" it can still join it if they want.
Now you need to set up encryption on your network - what options you have depends on the manufacturer and type of NIC that you have. The best encryption to choose is WPA-PSK but I don't know if that is available with Ad-Hoc setup. If not choose WEP encryption. Usually you have to type in a number or a passphrase to generate encryption keys. Whichever it is write it down
and store it somewhere safe so that when you come to add a third PC you will know what your encryption key was.
After you have entered the same data on both PCs you should have your network back operating but this time without any of your neighbours shared folders available.
If that all looks good you can set up Zone Alarm on both PCs.
Click Start>Run then type cmd
and hit enter.
In the black window that opens type ipconfig
Depending on your network you should see headings like:
"Ethernet adapter Local Area Connection" or "Ethernet adapter xxx Wireless Connection" or similar.
Below each of these headings will be a list of names followed by numbers, such as:
- there may be other entries. Make a note of all the "IP Address" numbers and "Default Gateway" numbers.
You should have two IP addresses for your PCs and you need to enter those addresses or that range of addresses in the Zone Alarm's "Trusted Zone" . I don't have Zone Alarm at the moment so I cannot 'talk you through it'. Your best bet is to go to the ZA help or their website for instructions.http://www.zonelabs.com/store/content/supp...en&lid=zasupp_h
