I hit this problem and found it was due to Kaspersky’s internal firewall that was blocking inbound TCP/UDP network traffic on the lan. This post here had the solution – see the comment by Dr Maveras near the bottom, which details how to reconfigure the Kaspersky Firewall to allow the traffic:-
I found the solution to _MY_ problem… I had been experiencing the same issue as in the original post – I could not access the XP pc from the W7 pc. But I could access the W7 pc from the XP pc.
I checked / tried these things first:
-Network Troubleshooter (W7 pc)
-Network Discovery turned on (W7 pc)
-Simple File Sharing (I could not even find this option anywhere on the XP pc)
-I was NOT able to ping the XP pc from the W7 pc
-I was able to ping the W7 pc from the XP pcSolution:
When I disabled my antivirus’ (KIS 2011) built in firewall, I immediately regained access to the XP pc from W7.It turns out that KIS 2011’s built in firewall had both “Local Services (TCP)” and “Local Services (UDP)” blocked under the “Packet Rules” tab. After changing the settings from “Blocked” to “According To Application Rule”, the problem was resolved.
I also had an issue where the XP pc did not always appear on the W7 pc network map. I resolved this issue by creating a shortcut to the XP pc on the W7 pc.
I hope this helps someone else.
