Hm Ntwk 3 XP-SP3 PCs, but only 1 is inaccessible
The spec-built PC with the problem is this: http://speccy.piriform.com/results/6...h8uyoHLX5JpWGi Environment: ----------------------------- 3 PCs in home network, all of which run XP SP3, AVG9 Free, and Kerio Personal Firewall PC names: Rapido, ESI-RENE1, Ironman 2Wire Gateway DSL home networking router from AT&T w/ WiFi & 4 LAN ports - deployed within the last year Simple file sharing is enabled Home network range has been added to allowable address list in all 3 firewall filter lists and to safe network lists on all 3 All 3 PCs are on WORKGROUP (name of the workgroup is WORKGROUP) No VPN or proxy Symptoms: ----------------------------- ESI-RENE1 can see all the shared files on Rapido and Ironman ESI-RENE1 can read/write to Rapido and Ironman Rapido and Ironman can read/write all the shared files on each other ESI-RENE1 shows in WORKGROUP via Network Places Properties on Rapido and Ironman, but when you click it, it errors out. Search for computer ESI-RENE1 from Rapido and Ironman returns null even though it displays in the GUI Troubleshooting done so far: ----------------------------- Verified ESI-RENE1 has internet connectivity Made sure sharing turned on with ESI-RENE1 for My Documents folder and other desired folders Verified simple file sharing set everywhere Tried disabling simple file sharing on all 3 to see if it would let me connect and authenticate w/ UID/pwd @ ESI-RENE1 -- NOPE Re-enabled simple file sharing - reattempted access to ESI-RENE1 shared files - NOPE Dropped firewalls on all 3 PCs Tried pinging - can ping everything except ESI-RENE1 Tried RDP - can use RDC to connect to anything except ESI-RENE1; cannot VNC to ESI-RENE1 even though VNC is running as service; only way I can connect to ESI-RENE1 is join.me or Team Viewer checked "arp -a" from ESI-RENE1 and they're all there checked "net view" from ESI-RENE1 and they're all there Checked NetBios - it's enabled Did ipconfig /release and ipconfig /renew on all 3 boxes then reverified all are showing in net view Made sure Windows Firewall and Windows Security services (My Computer Manage) are disabled, so it's not conflicting with Kerio Made sure all TCP/IP advanced properties set to automatic - just like Rapido and Ironman are (and they have no problems) Rebuilt TCP/IP stack Ran chkdsk /r Typical clean-up work on ESI-RENE1: Ran CCleaner, cleaned out unneeded programs and typical Windows trash, Ran MalwareBytes scan, Ran SuperAntiSpyware scan, defragged, got rid of temp junk, validated paths and application MD5's in Kerio, trimmed down what loads at startup Opened Home Networking and Firewall areas of router to check file sharing accessibility, and from the router all 3 show and have accessible files - viewed from ESI-RENE1's browser, \\Ironman and \\Rapido and \\ESI-RENE1 PINGing: can ping Ironman and Rapido from each other and from ESI-RENE1, but can't ping ESI-RENE1 from anywhere, although it resolves as correct IP address. Guess that means the router's doing right and the problem is within ESI-RENE1. There are 2 NIC cards in ESI-RENE1: made sure one is enabled other disabled and that enabled one has the cable connected; then switched the cable to the other NIC card and switched which one is enabled/disabled, but all the same symptoms persist - so it's not a flaky NIC card in ESI-RENE1 Unplugged the cables from the router and switched them all to different ports - same problems persist unchanged. So now I'm scratching my head - Looks to me like all the settings are correct, same for ESI-RENE1 as for Ironman and Rapido, and only ESI-RENE1 has these problems. If not for the very, very lengthy installation and customization process for ESI-RENE1 (due to special industry software and tons of plugins and scripts to make it fly fast), I'd just blow away the OS... but that would literally require over 2 weeks to get the system reinstalled and reconfigured, let alone figure out how to back up data beforehand with this kind of networking hamstring. What do I need to do to get ESI-RENE1 showing *and* accessible to the other PCs in WORKGROUP? Thanks, Rene "If it ain't broke, don't fix it." Fine - now it is, so I gotta fix it. |

Whoa!!!, you got a bad one there.
If Rene1 can use resources in the other PC's, Rene1 network is working OK. Since you cannot PING Rene1 from the outside, there is a Firewall setting in Rene1 blocking 'inbound' connections to Rene1. A procedure I had use to resolve some problems like that is: From control panel (on Rene1), run 'Network Setup Wizard', make sure you change the parameters to match your workgroup, and select share folders and printers, apply those settings, do not create floppy. That should clear whatever is blocking Rene1. Hope will work for you.

Just a thought, I know you said that you are running Kerio firewall - it isn't possible that Windows Firewall has turned itself on as well? I had something similar once (think it was SP2 though and can't remember the other type of firewall). Windows wasn't picking up that another firewall had installed itself so it turned itself back on. |

: Dropped firewalls on all 3 PCs Tried pinging - can ping everything except ESI-RENE1 Symptoms all point to a firewall. Somewhere. Do you have the Cisco VPN Client installed on that computer? If so, it contains a Stateful Firewall that is always enabled even when the VPN client isn't running. If this is your case, startup the VPN client, click the "Options" menu and un-check the firewall entry. HTH, JW |
