Windows 7 Problems access computers on my network.

[emolina]

Hello, when I upgrade my computers to Windows 7 at the beggining every was good but after I install yesterday Kaspersky internet security 2010 now when I try to access some computers in my network I receive an error message : "Windows cannot access \\computername , check the spelling of the name. Otherwise there might be a problem with your network" also I have a media server from Netgear and before yesterday was showing on the network with an icon like computer so I was able to access to the storage very easy just grag & drop files, but now just show like media device no like computer, so I dont have access anymore to the files. Can someone tell me if is a way to reset all this?
Thanks

Have you checked Kapersky to set up your network, or have you checked the logs to see exactly what is being blocked?
