Can't send attachements greater than 50 KB

[Ken]

I have been banging my head on this one all day. I even
spent most of
today looking at netnews for a solution to this one.

I'm using XP Home, with cable modem service.

I have 5 email accounts with my ISP. We have a Netgear
wireless
network with three computers on the network.

I'm having trouble sending any type of attachment that is
over 50 KB
from my computer. The outgoing is SMTP.

My ISP has a 10MB email disk quota limit, which there is
no space used.
I can verify my mail box size with the web mail client.

I have no problems sending 100 KB attachments on my
spouses computer,
which is just using on the the five email accounts the
ISP provides.

I tried to send >50 KB attachments with Netscape EMAIL,
Outlook
Express, and Outlook 2000, which I normally use and have
the save
problem. The send/receive goes to around 94-97% and just
sticks in the
out box. I'm sending doc files and jpegs as test files.
These same files
types send
fine as long as they are < 50 KB.

I completly disabled my McAfee Internet Security package
and still
have the same problem.

I even called a friend who has the same ISP and ask to
use one of his
spare POP3 email accounts, which I configured on Netscape
email and
got the same exact problem.

I only have problems sending files > 50KB and no problems
receiving files
greater
than 50 KB.

I tried an experiment in outlook, under properties, where
I can break
apart the message sent. I set this to break apart
messages greater than 50
KB
and was able to send a 120 KB file. I really don't want
to have to do
this as the norm,

I'm wondering if there is some kind of TCP/IP setting
that messed up.
Any help appreciated.

Do you have any plug-ins installed in Outlook? Try starting Outlook in
its safe mode ("outlook.exe /safe").

Do you have some compression archive software, like WinZip, PKZip, or
QuickView? For example, QuickView can be configured for a threshold at
which to compress attachments. The default is 50 KB. If the attachment
is smaller than this then there is no compression. If the attachment is
larger than this, QuickView will compress the file into a .zip file and
then attach it to your e-mail. Obviously the compression must be
performed outside of Outlook and then QuickView has to itself add the
attachment. Maybe your .zip tool is screwing up your attachments which
results in a hang in Outlook waiting for the plug-in to complete.

Do you have anti-virus software? Have you tried disable its e-mail
scanning features, especially for outbound messages?

having the same problem with similair software (McAfee
Internet Security Suite 2004 & Microsoft Outlook 2003)-
try this webpage:

http://support.microsoft.com/?kbid=827349

I haven't downloaded this Hotfix as the instalation looks
a bit tricky for me

hope this helps ?

I brought up outlook in safe mode and emails greater than 50KB still
just stayed hung in the sent folder. The sent progress bar was about
1/2 complete but no further progress. This probally rules out the
plug-ins as the culprit if I understand your email correctly. I also
completely disabled my virus software (McAfee Internet Security 2004).
Thanks for your help so far. Do you have any other possible options?
I'm hesitant to try the hot fix mentioned later in this thread since
it doesn't directly mention any problems with sending different file
sizes in the email. What do you think? Thanks for your help Vanguard!

It's been way too long, but I recall a discussion with another user
where he couldn't send e-mails (body and attachment) that were over
something like 10 KB in size, then it went to 5 KB, and eventually he
couldn't send any e-mails larger than 2KB in size. Somewhere we got
talking about the TCP/IP parameters being screwed up, so he reset them
to their defaults and his e-mail was working again. I believe the
command you enter in a DOS shell (aka Command Prompt) is:

netsh int ip reset

Under Windows 9x/ME, you could uninstall the TCP protocol from Windows,
reinstall it, and then rebind it to your connectoid so reset all its
parameters. Not possible in Windows XP, so I think this is how you're
supposed to reset TCP to a clean state. You can enter "netsh /?" to see
the parameters it accepts, then "netsh int /?" to see what that one
takes for parameters, and then "netsh int ip /?" to note the description
for the reset parameter.

Or maybe it was:

netsh int reset all

I just tried "netsh int ip reset" and it wanted another parameter for a
logfile name. I ran:

netsh int ip reset logfile.txt

and it did run and created the logfile.txt file where it recorded what
changes were made in the registry.

Thanks Dean for finding a solution to this elusive problem! It looks
like the problem of not being able to send email attachments greater
than 50KB is caused by the new McAfee Internet Security Suite 2004.
This problem has been verified on Outlook 2000, Outlook 3000, Netscape
Mail, Outlook Express so far. The problem is caused by a feature in
the McAfee Internet Secuirty Suite 2004 called WormWtopper. Once this
was disabled, I was able send email attachments greater than 50KB.
According to Dean, McAfee is aware of the problem but a fix is not yet
available. Here is the workaround that McAfee provided to Dean. Thanks
Dean for following through with McAfee and providing the workaround.
Everyone who owns McAfee Internet Security Suite 2004 should call
McAfee so that they put resources on this bug and get it fixed.

===================================================================
Disable WormStopper
Open the Security Center, click on VirusScan on the left side.
Click on configure VirusScan options


Click on Advanced


Click on the WormStopper tab.


Disable WormStopper.
Kill the Email Scanning Process

WinNT/2K/XP: Terminate the process MCVSESCN.exe
Win 98/ME: CTRL + ALT + DEL, end task on Mcvsescn
