Hi,

I have a small (3 computer) wired Peer/Peer TCP/IP LAN and am trying to add
another computer to it. The other computers all see each other, can browse
to each other, and appear under View Workgroup Computers.

The new computer appears under View Worgroup computers on the other
machines, and can be browsed to. However, if I try to connect to one of the
other computers from the new one I get the message "Rudby is not accessible.
You might not have permission to use this network resource. Contact system
administrator. Incorrect Function". Even the new computer itself doesn't
appear under its own Worgroup Computers.

I have set the new computer to share files, and given full permisson to each
drive. The Computer Browser service is running on all machines. I have
tried changing the Advanced WINS TCP/IP setting for each machine to NETBIOS
over TCP/IP (on the advice of KB318030 but still the same problem.

I am connecting via an OfficeConnect switch and Draytech ADSL router (acting
as DHCP server), and have tried dissabling the firwall on the router and
allowing NETBIOS. I have McAfee AV & Firewall installed and the LAN setup to
be allowed, but have also tried dissabling this firwall to bo avail.

On one occasion, after removing and reinstalling Microsoft File & Printer
Sharing I was able to connect from this computer, but on the next reboot I
was back to only being afle to connect to the new computer not from it, so
this may be irrelevent.

The new machine can acess the internet fine and ping the othr computers, and
the others can access it. It is only the ability to connect to the
othercomputers from the new one that doesn't work.

Any ideas what might be wrong or how I might cure it?
 
Hi Again,

Since posting this nI've run Browstat and find that there seems to be a
problem getting the list, but have no idea how to cure it? TResults as
follows:

Status for domain RUDBY on transport
\Device\NetBT_Tcpip_{93CB1A82-2D38-4AAF-A6F7-624008C6DF0E}
Browsing is active on domain.
Master browser name is: JANET
Could not connect to registry, error = 53 Unable to determine build
of browser master: 53
Unable to determine server information for browser master: 1
1 backup servers retrieved from master JANET
\\JANET
Unable to retrieve server list from JANET: 1

Thanks for any thoughts,

Phill.

Enable the firewall on the router! It protects all of the computers
from Internet hackers, and it's not causing the problem

The McAfee firewall on the new computer is probably causing the
problem. Un-install it.

Thanks for this Steve, don't know why I didn't try uninstaling McAfee
firewall - I guess I assumed disabling it did the same thing. Any idea why
having McAfee firwall enabled (or disabled for that matter!) would prevent
the new computer from seeing the others even when the LAN adresses are
entered as safe?

Thanks,

Phill.

You're welcome, Phill. I've seen several cases where firewall
programs (especially ZoneAlarm, Norton, and McAfee) interfere with
normal network access when they're apparently configured properly, and
even when they're disabled. Uninstalling them usually gets the
network to work again.

I attribute that problem to bad design and/or implementation, and the
problem seems to be getting worse as vendors add more "features" (some
of them verging on being nothing but marketing gimmicks) to their
firewalls.

I don't think that a knowledgeable user like you needs those features.
I recommend using a combination of hardware firewall (home broadband
router) and simple software firewall (Windows Firewall in XP SP2).

Thanks again Steve.

My router's firewall seems mainly to restrict Netbios. It has a "call
filter" than blocks Netbios and a "data filter" that blocks xNetbios > DNS.
To be honest I'm not really sure what that means or if that's enough (coupled
with Win XP SP2 firwall), or for that matter what Netbios over TCP/IP means.
The router does use NAT to allow a single IP to be used for WAN so I guess
that helps too?

Thanks again for al the help,

Phill.

You're welcome, Phill. File and printer sharing uses NetBIOS. I
don't know why it would be useful for a firewall to block NetBIOS
between computers on a typical home network.

As a byproduct of NAT, your router acts as a firewall between the
Internet and your computers. It only allows data in that one of your
computers has requested.
