E-Mail Attachments using Outlook 2003

[Ronnie]

I cannot send e-mail attachments using outlook 2003. The error message I get is that my server keeps timing out. I am on a broadband connection, so I find this a little unusual.

Can anyone help me with this please?

Many thanks

Try adjusting your MTU value. (You didn't state what operating system you
are using, so it is difficult to give specifics.)

Thanks for the reply, but I am sorry to say that I do not understand the MTU Value? Secondly, I am using outlook 2003 on Windows XP (Home Edition).

Again many thanks

Open Regedit and go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Set/create two values (these are both DWORD values)

EnablePMTUDiscovery = 1
EnablePMTUBHDetect = 1


Reboot the machine and then try sending an attachment.

Thanks again. Got as far as tcpip/parameters? Then I become a little unstuck; Not quite sure where I create these two values, sorry for being a pain.

No problem, if both are missing just do this.

* Open regedit and go to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
* Make sure the folder above is selected
* Select Edit > New > DWORD value
* Change "New Value #1" to EnablePMTUDiscovery
* Double click on EnablePMTUDiscovery and set it to 1
* Repeat 3 steps above for EnablePMTUBHDetect
