How to block local hostname under wrokgroup

[rsumook]

Let me clear my sample hostname and IP Address
this is the actual happening in our network

Pfsense LAN Interfaces and Setup
LAN1: WAN ISP IP
LAN2: 192.168.50.1 - 192.168.50.254
LAN3: 10.200.0.1 - 10.200.7.254

OS: windows 7 pro
Hostname: pc50
IP address: 192.168.50.150 is belong to LAN2 Subnet

OS: Windows 7 pro
Hostname: win58
IP Address: 10.200.7.158 is belong to SUBNET of LAN3

here is my problem
from win58 using this command \pc50 or \PC50 in windows explorer username and password prompted See Attached file pc502.png
but using IP Address to access the shared folder to pc50 is Windows Cannot Access \192.168.50.150 see attached file 150.png

see attached win58.png for more info

from win58 ping

Something is responding same-subnet (local network, not through the firewall) as host pc50 on IPv6. When you connect to \pc50 you are connecting to whatever that is and are not going through the firewall.

but the IPv6 is not enabled in pfsense how does IPv6 can ping to our network while firewall rules is Denied for IPv4* and  IPv6*

so if thats the case how am i going to prevent that is the pFsense has capable to block the subnet?

any suggestions…

thanks

You have something hosed up at layer 2 or something else set to respond to that name.

Firewall can't help you there.

For now my temporarily solution is to pointed into wrong IP Addres like 127.0.0.1 to the hostname of pc50 thru modifying of hosts file from windows system.

But soon he will discover that and i dont want to argue with him. Can you please explain more details about hosed up at layer 2 well for me if possible one server to manage this kind of problem not one by one do modifying of hosts file.

Thanks

That IPv6 address starting with fe80 is on interface "11" as far as windows is concerned. That is a link-local address. The firewall is not involved in communication with that address at all. This is not a pfSense problem. Check your local network.

Hi

I dont know what would i check on our local network no idea where to start, the only i know he did something in windows services and windows firewall is disabled but still no idea i tried other windows system i disabled the firewall and access the hostname like \win45 i get access denied even in IP address and reboot many times.

This is not a pfSense problem. Check your local network.

What i do first is to review and check all connection cable from Switch HUb device and review one by one  unplugged and plugged it. then finally found the problem :)

so the problem is from the LAN1 LAN2 and LAN3 connected to same Switch HUB1,2 and 3 device so i removed LAN1 and connect to HUB1 Only and LAN2 to HUB2 Only same to LAN3 to HUB3

so HUB1, HUB2 and HUB3 are not connected to each other anymore then i tried LAN2 to access the shared folder from PC50 were the subnet is from LAN1 which is 192.168.1.10 whoaalllaaaa i get access denied

Thank you soooo much for giving me a time to understand and i learned so much guys
