System has Internet, but can't browse Lan...?

[Kenneth]

Howdy,

We have six systems behind a router.

All can browse Internet, and all but one can browse the Lan
reading, and writing, to one another.

One system (an XP box - all others are Win 2000 Pro) can
browse Internet, but cannot browse our Lan.

When, from that machine, I attempt to explore the workgroup,
nothing shows up. When I attempt to ping other systems, (say
one called "Joe" I get the error: "Could not find host Joe."
If I attempt to ping the offending system from another on
the Lan, I get "Unknown host Sue."

I should also add that when I go into that system's Control
Panel | Windows Firewall it shows that the Firewall is OFF.

But, it I go into Control Panel | Security Center, it shows
Firewall ON and explains that Norton Internet Worm
Protection is activated. (I have no idea what that Norton
product is, and cannot find it on the system in any case.)

And finally, all this is new. That is, this one system had
been able to browse the Lan properly. I just discovered the
problem because we had it set to backup to another system on
the Lan, but new it is generating backup errors because it
can no longer see that other system.

I would welcome any assistance on this hassle...

Sincere thanks,

Looks like a firewall/NIS [Norton Internet Security]issue, yet you say
you are unaware of it's presence ?, do some more digging and remove
Norton's.

Hi Roberto,

Originally, I thought just as you did...

But, I looked in All Programs but other than Ghost, nothing
from Norton is listed.

Then, I looked in Add Remove Programs with the same result.

Might you have any further thoughts about this?

Sincere thanks,

Have a look in the registry for instances of Norton.
Start > Run> regedit [enter]
Goto Edit > find > Symantec [hit F3 to continue if anything turns up]
Then do the same using Norton as your search term.

Hi again Roberto,

This is getting stranger and stranger...

First, when I do the searches you suggest, I get lot of hits
for Norton, and a few for Symantec.

This despite having run the Symantec Removal Tool...

Are you suggesting that I remove these manually?

Next, (and weirder), as I have said, the system in question
has access to the Internet, but cannot browse our Lan. That
continues to be true, but only when I try to access the Lan
via Cat5.

I just brought the system to my home where we use wireless.

To my surprise, when I switched the system to access via
wireless, it had Internet, and also could browse our Lan.

Can you suggest anything that could cause this situation?

Thanks for any further help,

Removal tool eh !!! [it's a joke they aught to be ashamed of
themselves ]
Since you have Ghost, some of those entries will be for it -err on the
safe side and leave them for now.

I would try
1. different CAT5 cable
2. different NIC or see if there is an updated driver for the
current one.

Hi again Roberto,

I have (finally) had some success...

I un-installed, then re-installed File & Printer Sharing.
The moment I had done that, the Network Places field
populated, and I had access to my Lan.

I have no idea what caused the problem initially, but
apparently something became corrupted. Now, it is working
again.

I will also mention that I removed Ghost, ran the Symantec
removal tool <g>, and then manually removed all entries in
the registry with "Norton" or "Symantec". (There were a few
that could not be removed.)

Then, I installed True Image. We have been very happy with
that product for backup on all of our other systems.

All the best, and thanks again,
