Hello, New here to the forum, and I have a recent issue regarding one of the computers on my network (home). I will try to make it as short as possible. I have two PC's running XP, A Linksys WRT54g Router, a PS3 and a Roku Soundbridge(media streamer) on my network. Suddenly I noticed that the PS3 and the Roku(SB) no longer "see" computer#2, but computer#2 "see's" both of these devices. I can see computer#2 on computer #1 and vise versa. On computer#2, I can successfully ping every computer/device on the network. Computer #2 shows on Linksys Easylink Advisor as connected. I can print from computer#2 across the network.(printer is hooked to computer#1). I made sure File sharing is "on" and checked windows firewall to make sure the required ports are open. Also made sure that "windows media player network sharing service" is running. I have tried to reset the Roku and PS3 with no luck. What have I not tried yet? Sorry if this is confusing and/or any of my terminology is incorrect, but I am frustrated with this issue. Thanks in advance!
