Tell  you  what,  rather  then  just  knocking me back like that. Take your main
machine  it  happens with and try it. FYI I'm a Senior Support guy and the first
thing I teach my staff under me is to attack a problem from all likely angles.

ANd  you  say  its  impossible  to  have  bad  ram  on  three computers - no not
impossible. Unlikely, but not impossible.

Remove  the  impossible  and  whatever  is  left,  even  the  unlikely - must be
suspected.

I've seen stranger things that happen.

Lets look at what you've said.

Attachments  come  in and on those machines they seem corrupted. JPG's show some
file corruption within them right?

Documents don't open.

Therefore  something  isn't  being  read from message store correctly. Seeing as
(IIRC)  you're  storing  attachments  with  the message in the store its safe to
assume  that  for  some  reason the decoding of the attachment from store is not
going right.

I said that I suspect

a) Its being corrupted in memory as the attachment is being reconstructed.

Because  its  obvious (as other people can read your attachments when forwarded)
that  the  deconstruction  process  is  going  wrong.  If they are stored in the
message  base  coded then there is no real reconstruction going on in forwarding
them - they are merely block copied and sent out.

Also  you  mentioned  ZA  and  mail checking - well I had to rebuild an exchange
server  with  a  12gb  database  because a virus checker was silently corrupting
attachments due to what is called (oh how I laugh) "Known Issues"....

So any software that sits between you and the mail store is also suspect. Mainly
because  the process of "checking" goes on (1) when writing the message to store
and (2) retrieving from store.

So there are several angles to try.

Me  -  I'd isolate the easy ones first. Change the RAM - try it. Still the same?
then  strike  ram  from  it. Check to remove overheating from the equation. Many
people just slam in any old RAM into their PC's without a second thought for the
issues. Mismatching RAM is a big troublemaker....

If  you  have  three machines then strip one down to windows and TB!. Remove all
extraneous  software  from  it.  You  may,  for example, have an esoteric bit of
software that conflicts.
