I’ve got a local network at home set up through a Linksys router, with a cable modem on the other end. I’ve got a laptop, a desktop, and a DVR. Everything can access the internet just fine. The laptop can ping everything, including the desktop. The desktop can ping itself, the router, and remote sites on the internet, but attempts to ping anything on the local network just get “Request timed out.” Both computers run XP, but have different workgroups and domains. The desktop runs Windows Firewall, but turning it off didn’t help. My main concern is getting the desktop to talk to the DVR, but hopefully the answer lies in why one computer can ping the other but not vice-versa, which is a symptom I could not find in any help files or web searching. Thanks in advance for any help, because I’m stumped.
