Windows 7 workstation is only accessible from local subnet

I have a windows 7 workstation and we can't ping and access the share folder in this workstation from different subnet. I have tried turning off the firewall, and inbound ICMPv4 rules are set to allow incoming from any IP Address. I still can't ping this workstation from different subnet.

However, I can ping other workstation on different subnet, from this WIndows 7 workstation.

Try clearing the arp cache on the workstation that you CANT ping the Win7 pc from..i.e. not the issue pc, but the other one

arp -d *

this is down to your ip routing - you have ip routing set up one way - what you using to connect those subnets - if router check its config.

or you can add manually route

cmd (as admin)

route add 10.0.0.0 mask 255.0.0.0 192.168.0.1 metric 2

Also you can try


cmd  

tracert  Fullyquilifiedcomputername

(like pc1.domainname.com)

Truthfully, unless if someone was messing with Win7 on that PC, this sounds more like a router/switch configuration issue.

Other PCs on that subnet can ping it and the one computer that cannot ping the Win7 PC can ping other PCs expect the Win 7. I turned off the firewall and does not seem to help. It something about computers on different subnet not able to ping. The network layer is fine I really think it something with Win 7.

Are they on same switch?
If so reboot switch

Is it just ping that isn't working?

This sounds like a name resolution issue.
Can you ping using its Fully Qualified Domain Name rather than just its Hostname?
Can you ping by its IP?

If so, then it is name resolution.  Do an  ipconfig /all  and see what its primary DNS suffix is and which DNS and DHCP servers it is using.  Is its name registered in DNS (look in the DNS GUI or use nslookup)?  Is your DHCP server informing the workstations of a suitable DNS Suffix search list so others know which DNS zone to query?

I had a machine that was XP with same IP and all network config.  We replaced it with Win7 and put same network config and it stopped working yet PCs on the same subnet can ping this PC. I thought it was a Windows firewall issue and turned it off but that did not help.

smckeown777Commented:
Ok, so you had a working XP machine, then replaced with a Win7 and set the IP the exact same?

So basically this is an arp issue, either on one of the switches or the router that connects the 2 subnets the arp cache hasn't expired properly - have you rebooted your switches/routers?

To break it down to simple terms when you ping an IP it sends a broadcast message out to ask 'who is 192.168.0.3' for example
When it finds out it links this IP with the pc's MAC-Address(this is the arp process)
PC's have an arp cache, so do switches/routers
So if you replaced a working XP machine with a Win7(this has a different mac) this can happen if the arp cache isn't clearing properly

How many switches/routers have you?

Have you checked DNS like I said?

If you ping it by hostname (and FQDN) from the other subnet, does it resolve to the correct IP?

Hello everyone, I did not see how it can be DNS issue as this was from IP. The switches and routers were restarted which also did not help.

What it turned out to be was the Kasperskey AV which was blocking connections from other subnets. Thanks for all the possible fixes.
