network issues

[chris wooley]

i have several shares set up on my network. when i try to
access them, i get the error:

\\server\share is not accessable. you may not have the
permissions...bla bla bla.

an internal windows 2000 error has occoured.

1. i'm using xp on both machines. i know that xp is
basically 2000 with a new look, but it still seems
strange to say that.

2. full permissions are set, so it can't be a share
issue. the user has admin rights over the share. i have
checked and triple checked that.

3. there are no firewalls or other communication blocking
devices in place.

4. here is the kicker... sometimes the share will work
normally exactly like it is supposed to, but sometimes
70% it won't... in other words, sometimes it can access
the files on the remote computer, and, without anything
changeing, 20 minutes later, i can't.

what is going on here?

I had the same/similar probem sharing my USB 2.0 drive for backup purposes.
Actually
I had two problems and solutions are below.

Please let me know if the work - I'm keeping score!

Problem 1
========

If you are sure you have set up your accounts and shares correctly but you
still can't access a machine over your LAN and you get either access
permission errors or "Not enough server storage" (or perhaps other
messages?) then his might be worth checking.

Look in the event log on the "server". This might be an ordinary PC in the
case of a home LAN, either way it's the PC hosting the share you are trying
to contact. See if there is an entry telling you the irpstacksize is too
small.

I believe this problems may be due to Norton Antivirus S/W...

Norton have this advisory (long URL may wrap to new line and need repair)

and Microsoft have this one..

HOWEVER the above only mention the error message being "Not enough server
storage...". I found it can also give access permission errors (something
like "Access denied" or "Insufficient acesss", I can't remember exactly).
These are really confusing to someone trying to set up a home LAN.

Here is what I found...

irpstacksize = 11 (dec) causes access permission errors.

irpstacksize = 13/14 the error changed to "Not enough server storage" or
similar.

irpstacksize = 15 and my network shares now work fine.


Problem 2
========

Once I had fixed the above I found my backup would abort half way through
with a "Delayed Write Failure". This is tricky to explain. The problem seems
to occur because shared folders can cause excess network traffic. I read
somewhere that every time the content of a shared folder is changed messages
are sent to all computers/accounts that have access to the share (eg every
time Drive Image appends a byte or two of data to the backup multiple
messages are sent out and this slows down the LAN to the point that a "write
buffer" gets overwritten).

The fix for me was to restructure the folders I was using to hold backups
and "push the share down a level"....

Before...

I shared a folder called "Backups" on PC1 and arranged for PC1 to write to
subfolder "Backups\PC1" and PC2 to write to Backups\PC2 etc.

After...

I removed the share from "Backups" and shared Backups\PC2 only. (Backups\PC1
does not need to be shared).

This seems to have cured the problem.
