Unable to connect to shared directory, shared files from XP Pro client to XP Home Client on simple L

[Ted Levy]

I have a simple LAN with four clients and wish to share "My Documents" among
the four. Two are XP Pro and two are XP Home. This was working with no
problem prior to some point in the recent past which may or may not be after
I installed SP2. None of the clients can view, open, read, change, etc.
files on the "shared" directory on either of the two "Home" machines. All of
the clients can view, open, read, change, etc. files on the shared directory
on either of the two "Pro" machines.

A printer connected to one of the two Home machines is shared and accessible
by all four with no problem. Any of the four machines displays the shared
directory in View workgroup computers. The directories can be selected and
added to "Network Places". When double-clicking on the "shared" directories,
the error is

"\\computername\My Documents is not accessible. You might not have
permission to use this network resource. Contact the administrator of this
server to find out if you have access permissions.

Not enough server storage is available to process this command."

Sometimes the same message appears with a different last paragraph, "Network
path not found." I cannot reliably reproduce the appearance of the second
message; usually it is the first one which shows.

All clients are fully updated to SP2 and all subsequent fixes. All clients
have been VERY thoroughly virus-checked with the latest update of NAV Pro
2004 or 2003 and malware checked with the latest updates of Ad-Aware SE,
Spy-Bot, Bazooka, and Registry Mechanic and they are clean.

I thought this might have been a ZoneAlarm problem but the when ZA is turned
off the problem is the same. I have ZA on all the machines normally (latest
5.5 release) and the connection is via a Linksys WRT54G wireless router with
one of the Pro clients and one of the Home clients wired and one of each
wireless. In any case nothing there has changed for more than a year and
this problem is at most 3 - 4 months recent. My Internet connection is via
cable (Comcast). Simple file sharing is enabled on all four computers which
are virtually identically configured network-wise.

I am at a loss. Any ideas would be appreciated.

Here is the fix ...

http://support.microsoft.com/default.aspx?scid=kb;en-us;177078. The problem
evidently is caused by NAV. The KB Article is headed, "Antivirus software
may cause Event ID 2011." It can be found by searching the KB for the text
of the error message "Not enough server storage is available to process this
command" searching Windows XP as type Full Text using Any of the Words
Entered.

The candidate articles were this one and another, #106167, but the Antivirus
header discussed NAV so that is where I went. The article describes a
further confirming symptom which is the occurrence of an event ID 2011
visible in the Event Viewer "System" category. When I checked there, I found
a slew of these events, going back to 7/30/04. I applied the fix and found
the suspect key (something called the IRP Stack Size among the lanmanserver
parameters, whatever they are) just where the article said it would be and
changed it as indicated; the problem went away.

The error message was correct, evidently ... Not enough server storage is
available to process this command. But what is that supposed to mean, and
what am I supposed to do about it? In short, a semi-useless message. The
trickiest part of finding this answer is realizing that the message pertains
to the machine where the share is, not the machine that displays the
message. Perhaps some day, some genius will figure out a way to provide
error messages that actually contain within them a means to fix the problem.
Oh well.

Evidently the suspicious factoid that the inaccessible shares were on the XP
Home machines vs. the XP Pro machines was a red herring.

I subsequently found a post on this board from Ron Lowe dated mid-October
(about 15000 posts back) which had this answer also.
