"unknown publisher" on exe run from 2003 server network

We have an application that is distrubted as compiled exe's. Clients
download the exe's in zip files from our web site.

Today, we had a client that downloaded the zip file using a Windows XP
client with SP2, unzipped it, and put the exe on a Windows2003 server share.
>From that point on ALL clients that tried to run the exe were getting the
pop-up box of "the publisher could not be verified". If they said "run" then
it would come up with something about "operating system blocked access to
this file".

I copied the exe from my machine (also XP/SP2) to the server, and it did the
same thing. Eventually, the client re-downloaded the zip file directly from
the 2003 server workstation, and then the problem went away.

In searching the web, I saw a lot of references to this error and lack of
digital signature on our exe's downloaded. It almost sounds like XPSP2 is
somehow "marking" the exe (even though it is inside of a zip file) as
downloaded content. However, if you run it from the XPsp2 clients C: drive,
it runs fine. It only fails when it is run from the 2003 server share.

So, C: drive of XPsp2 is fine. File downloaded via 2003 is fine. File
downloaded via XPsp2, and executed from 2003 share, fails.

I'm concerned this may affect more clients, or if 2003 is "patched" like
xpsp2, then it may start "marking" them exe's as downloaded content also.

I saw some references to changing the group security policy to turn off this
warning/check for attachments, but would that then disable it on all
workstations in the domain when they open attachments in mail or the internet?

Anyone have any ideas of what causes this or what we can do to get around it?
