Cannot share files between 2 laptops

[PeterCaldwell]

OK, I'm a VBA programmer, been programming for 30 odd years, but I cannot get our two laptops sharing a Public folder.
I have a Vista machine, fully updated. The other machine is an emachine with Windows 7 starter, again fully updated. We have one internet connection in the flat that is connected to the Landlords router to which I do not have access. I got a Dlink hub (8 port desktop switch), both laptops are connected to that and the hub to the internet point. Both laptops have internet no problems at all, but neither laptop can see the other one. I've even pinged each others IP addresses and they just time out.
They both have the network set as private/home, they both have network discovery on, public folder sharing on, password protection off. The public folder on the vista machine has sharing on and Everyone having full control. Workgroup name is the same on both machines. The vista machine calls the network - Network 10 and the other machine calls it Network, but I can't find a way to change that if it's a factor. Windows Firewall is off on both machines. Comodo Firewall is on but I quit that on both machines and it didn't make any difference - so I assume that isn't the problem. Each machine can see itself under Network but that is it.
Any ideas, anyone?

can you type the ipconfig /all
make sure that's you set the class IP address and the subnet mask.

sorry for the late reply, you're set the ip address manually. but it's seems not problem at there.
anyway you're using hub 8 port on it? can you change to the other port..and see below work or not.
and also make sure that's the firewall is off(on your system and antivirus)

 

[PeterCaldwell]

a) what "below" and b) I'm not turning off my firewall and antivirus, why would I have to.

 

[ryo]

ups sorry..i means below is see that the connection is connected or not.
and try to turn off your firewall.

 

[PeterCaldwell]

Again what "below" and again I'm not turning off my firewall. You are beginning to worry me? You've said nothing of use yet, all you've done is post adverts for .pst file repairs as far as I can see!!!

Try this link, you may want to consider that Comodo is causing this problem in which case reconfiguring the firewall or uninstalling it may be best.

As chev stated, uninstall Comodo and re-enable the Windows firewall. When it comes to networking, nearly all of the problems are related to third party security applications that are not properly configured.
