XP unable to access networked computer

[cherkhan]

Hi

I have much the same problem as other folks on here. For some reason I have
lost access to the network and file sharing. Sharing printers works fine but
I am not able to access my wireless laptop from the desktop or vice versa.
This all apeared to work fine before I loaded SP2. I have disabled the MS
firewall and still the problem persists.

I have rerun the network setup wizards and ensured that both compueters are
running in the same work group, still no access. The message reads 'you may
not have authority to access this computer' or 'MSHOME no longer exists'
whilst it is actually staring me in the face. Another message states
insufficent storage on the server to complete the task.

I have to admit to being at a total loss now. Is there a chance that even
though I have disabled the firewall in the security settings screen, that
some strange quirk is still blocking access to the network?

I have even setup new directories and set them to file share and still the
same problem, no access!

Any advice would be appreciated before I go back to wet string and tin cans.

Dave J.

PS

I use XP Home edition both on the laptop and desktop.

Dave,

Please start by providing ipconfig information for each computer.
Start - Run - "cmd". Type "ipconfig /all >c:\ipconfig.txt" into the command
window - Open c:\ipconfig.txt in Notepad, make sure that Format - Word Wrap is
NOT checked!, copy and paste entire contents into your next post.

Make sure that the Guest account is enabled, on each computer. Enable Guest
with Start - Run - "cmd" - type "net user guest /active:yes" in the command
window.

Look at registry key [HKLM\System\CurrentControlSet\Control\Lsa], value
restrictanonymous.

The above articles refer to Windows 2000. Remember WinXP is NT V5.1, and Win2K
is NT V5.0.

Have you used the Registry Editor before? If not, it's a scary tool, but it's
pretty simple once you get used to it. Here are a couple articles that might
help:

<http://www.annoyances.org/exec/show/registry>

Just remember to backup the key (create a registry patch) for
[HKLM\System\CurrentControlSet\Control\Lsa] before making any changes, if
appropriate.

From the Annoyances article:
You can create a Registry patch by opening the Registry Editor, selecting a
branch, and choosing Export from the File menu. Then, specify a filename, and
press OK. You can then view the Registry patch file by opening it in Notepad
(right-click on it and select Edit). Again, just double-click on a Registry
patch file (or use Import in the Registry Editor's File menu) to apply it to the
registry.

Paranoia comes from experience - and is not necessarily a bad thing.

This error indicates that you are falling foul of the IRPStackSize bug.

The problem is on the machine you are attempting to connect to,
not the machine where you see the error message.

On the computer you are attempting to connect to,
Check the event viewer for an event ID 2011.

Usual fix :
You need to fix a parameter called IRPStackSize

On the computer you are attempting to connect to,
Set the IRPStackSize back to the default (15 ).
Perform the following steps:

1. Start the registry editor (e.g., regedit.exe).
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\lanmanserver\parameters.
3. Double-click IRPStackSize
(or if this registry setting doesn't exist,create it of
type DWORD and ensure the case is correct).
4. Change the base to decimal, set the value to 15, and click OK.
5. Reboot the computer.

Norton AV is usual suspect for breaking it.

There's a KB article about this, too.
