Hi,
I have a network of 4
computers<http://www.anetforums.com/posts.aspx?Action=Reply&PostIndex=185888&ThreadIndex=42837&ForumIndex=30&redir=%2fposts.aspx%3fThreadIndex%3d42837%26ForumIndex%3d#>(3
laptops, 1 pc) connected to a 10Mbps hub. Let's name them pc1, pc2,
pc3,
pc4.
3 of them have OEM Windows XP Pro EN w/SP2. 1 have window 2000 pro
All have TCP/IP and NetBios installed.
All get IP from DHCP (ADSL modem/router also connected to the hub) in range
10.0.0.1 - 10.0.0.4.
All in group Workgroup (no domain).

Ping by IP address and computer name works great between all computers (each
way).
E.g. pc1 can ping pc2, pc3, pc4 and vice versa.

Each computer has at least 1 shared folder (Simple File
Sharing<http://www.anetforums.com/posts.aspx?Action=Reply&PostIndex=185888&ThreadIndex=42837&ForumIndex=30&redir=%2fposts.aspx%3fThreadIndex%3d42837%26ForumIndex%3d#>in
Win XP). Each computer can see all the other in "view workgroup
computers". All can access shared folders of every other computer except
one! pc1 can't access pc2 and after about 1 minute of "thinking" it writes
out:

\\pc2 is not accessible. You might not have permission to use this network
resource. Contact the administrator of this
server<http://www.anetforums.com/posts.aspx?Action=Reply&PostIndex=185888&ThreadIndex=42837&ForumIndex=30&redir=%2fposts.aspx%3fThreadIndex%3d42837%26ForumIndex%3d#>to
find out if you have access permissions.
The network path was not found.

I tried changing computer names, changing IPs, switching cables in the hub -
nothing works.
Turned off all the firewalls.
Unistalled NetBIOS on all the computers for a while (works even worse!).
I even tried to connect the the computers (pc1 and pc2) directly through a
cross-wired cable. And still the same result: pc2 can access pc1, but pc1
can't open pc2. (pc3 opens pc1, pc2, pc4 without any problems, etc).
I tried changing NodeType and DhcpNodeType in windows registry
(HLM\SYSTEM\CurrentControlSet\Services\NetBT\Parameters) to 4 (mixed) on all
computers so that "ipconfig /all" looks almost absolutely the same (even
though I don't exactly know what it is for [image: Emoticon] ) - didn't help

Booted in Safe Mode with
Networking<http://www.anetforums.com/posts.aspx?Action=Reply&PostIndex=185888&ThreadIndex=42837&ForumIndex=30&redir=%2fposts.aspx%3fThreadIndex%3d42837%26ForumIndex%3d#>-
well I didn't even find the "view workgroup computers" there but the
mapped drives didn't work (one way again).
I changed network adapter in pc2 (pc1 is laptop).

I'm clueless and desperate! Please help!

I don't want to reinstall Windows on pc1 and I don't even know if actually
it isn't a problem of pc2 ???

Interesting conclusion: if you got my point right then you will realize that
removing ANY of the two computers (pc1, pc2) leaves me with a perfectly
working windows network of 3 computers without any problem [image: Emoticon]
