Two Computers on Network Not Talking?

Specs: Windows Vista
Hi all,

I have a network set up with about 7 computers connected through a Belkin Wireless-N+ router. All of the computers seem to work fine except two, which are unable to access eachothers files or see each other on the network. I should mention that every other computer on the network can access / ping these computers, but they can not access / ping each other.

Both are Vista computers with no firewalls (Windows or otherwise) and have no problem accessing the other computers besides each other. Computer A is the only computer wired via Lan and computer B is connected wirelessly.

When I ping Computer B from Computer A and vice versa, I have about 50% packet loss no matter how many requests I make. This all seems very strange to me since its only two computers that are incompatible with eachother while the rest of the network is fine? Any ideas?

netbios over tcp/ip enabled on both? Wins tab in tcp/ip properties
50% packet loss is not good at all. Have you tried having these both wired to the router?

Thanks for a quick response, wanderer.

Netbios was actually not enabled on both, which I just changed with no result. The computers now show up in My Network Places but are still unaccessable due to a timeout after trying to access them.

I have not tried placing both on LAN yet and think that might be the next step. It's going to be a pain to reach with cable but I can't think of any other solution.

what is shared on each?
any other protocols other than tcp/ip?

Both the computers have public folders shared as well as a folder on their Harddrives. I noticed they weren't in the same workgroup and changed that, but it didn't help anything. They both now show up without fail in Network Places but I still cant connect. The error is thrown "Windows cannot access \\ComputerNameHere"

create a matching user account on each and using the same password logon both. Now can you access the shares?

Shares set to everyone with full control?

Also, I dont know if this helps, but when I tracert any computer on my network I get something like
<1ms <1ms <1ms ComputerName 192.168.bla.bla
Trace complete

When i do the same to the computer that is not responding correctly I see

* 5ms * Computer2Name 192.168.bla.bla
3ms * * Computer2Name 192.168.bla.bla
<1 ms * 1ms Computer2Name 192.168.bla.bla

It seems like it's getting stuck and theres packet loss? Weird - anyone have an idea?

Both computers have a matching user account on each and all the folders are set to be shared with everyone.

Either way, I would assume I could ping the computer regardless of what is or is not shared.

What was the result of putting both together wired?

packet loss can be from faulty nics or congestion on the network.

You can only ping if the software firewalls are set to allow it.
