I have a wireless network setup comprising of a Windows 7 desktop and a Vista laptop
Everything worked fine but I suddenly have found that my computer sharing network setup is no longer working.
When I try to access my Desktop PC from my laptop the Desktop Computer PC icon shows,but when I click on it I get a message
“Windows cannot access Desktop Windows has sent the request to the DNS server and that name was unknown"
When I try to access the laptop from my Desktop’s Windows7 (control panel>network sharing center) the Laptop icon no longer shows as it did previously.
Any suggestions on what is wrong and how to fix the problem greatly appreciated!
