Accessing a network


Mac Apple

Hi all. Didnt know where to put thread so hope its ok here. Updated to 10.3.2 today and now I can see other computers on my network.
The attachment shows what I can see.
I click on connect and it says “ The alias “(computername)” could not be opened, because the original item cannot be found.”
Does anybody know how to access these?
My friend on his PC can access some but I cant!
any help appreciated.
Cheers :D
