Windows XP networking problem

[BCC]

Hi,

I have a netgear wireless router, which I use to connect my desktop machine
via cable, and my laptop via the wireless card. The ip address of the
desktop is 192.168.0.2, and the laptop is .3.

Everything works great, except sharing files/folders/drives between
machines. So here's what I see going on:

From the desktop, I can see, and access files/folders that are shared on the
laptop. But from the laptop, I cannot access any of the shared stuff from
the desktop. If I go to 'network places' -> 'View workgroup computers', I
can see both machines under my domain 'MSHOME'. But if (from the laptop) I
try to open the desktop machine, I get the 'You might not have permission to
use this network resource' error message.

I have run the network wizard, disabled all the xp firewalls, rebooted the
machines several times with different network settings, but nothing changes.

I can ping each machine from the other without a problem, so from what I can
tell, the machines are clearly on the same network, and both machines are
clearly under the same domain.

Help! Ive googled like a nut and scoured the forums for a solution, but no
luck.

Thanks,
Bryan

Bryan,

Are the two computers on a domain, or a workgroup?

Please provide ipconfig information for each computer.
Start - Run - "cmd". Type "ipconfig /all >c:\ipconfig.txt" into the command
window - Open c:\ipconfig.txt in Notepad, copy and paste into your next post.
Identify operating system with each ipconfig listing.

On any XP Pro computer, check to see if Simple File Sharing (Control Panel -
Folder Options - View - Advanced settings) is enabled or disabled. With XP Pro,
you need to have the SFS settings properly set on each computer.

With XP Pro, if SFS is disabled, check the Local Security Policy (Control Panel
- Administrative Tools). Under Local Policies - Security Options, look at
"Network access: Sharing and security model", and ensure it's set to "Classic -
local users authenticate as themselves".

With XP Pro, if you set the Local Security Policy to "Guest only", make sure
that the Guest account is enabled, and has an identical, non-blank, password on
all computers. If "Classic", setup and use a common account with identical,
non-blank, password on all computers.

For XP Home, OR for XP Pro with Simple File Sharing enabled, make sure that the
Guest account is enabled, with identical, non-blank passwords, on each computer.

Is the XP firewall the only one ever involved on EITHER computer?

Chuck

Okay, output from the XP Pro machine (desktop connected via ethernet to
router). This is the one I cannot access from the other machine:

Nope, I have Kerio personal firewall on both machines. I disabled it on
both when I began trying to figure this out, but I could access ALN from
NICROS2 even with the firewall enabled.

Thanks Chuck! Look forward to hearing your response.

What OS is on ALN?

SFS was enabled on NICROS2. Is is supposed to be enabled or disabled?

If ALN is XP Pro also, IMHO you should disable SFS on both hosts. If ALN is XP
Home or any 9x variant (ME,98,95), you should enable SFS on ALN.

This is set this way.

computer.

If you use SFS (if NICROS2 is NOT XP Pro), make sure the Guest account is
enabled on both computers, and set a password.

Since you have a wireless network, if you can avoid using the Guest account for
network authentication (if both computers are XP Pro), you should do so. If
NICROS2 is XP Home or 9x, you are stuck with SFS, so you need to enable SFS on
ALN.

Here's two good articles from Microsoft:
http://support.microsoft.com/default.aspx?kbid=304040
<http://www.microsoft.com/downloads/...db-aef8-4bef-925e-7ac9be791028&DisplayLang=en>

If you disable SFS on BOTH computers (if NICROS2 is XP Pro), which you should,
make sure you setup and use a common account with identical, non-blank password
on both computers.

Nope, I have Kerio personal firewall on both machines. I disabled it on
both when I began trying to figure this out, but I could access ALN from
NICROS2 even with the firewall enabled.

Many personal firewalls (not Kerio as of yet) are known (I have advised others)
for not disabling properly - ie, when disabled, file sharing does not work. If
the above instructions about SFS do not help, you will need to recheck your
settings in Kerio - and configure each for file sharing, by opening ports TCP
139, 445 and UDP 137, 138, 445, and / or by identifying the other computer as
present in the Local (Trusted) zone. Firewall configurations are a very common
cause of (network) browser, and file sharing, problems.

Had the same problem with Mcafee's personal firewall.

the solution for me was simple. Under the NIC properties, WINS jus
enabled the NetBIOS over TCP/IP and it's working.

hope this will hel
