Recently I rplaced my motherboard, upgraded my CPU, and Ram. After about 1 week I realized I had forgotten to install Norton Anti-Virus 2002. I reinstalled the Anti-Virus with no problems. (No viruses detected after all updates.) Then when I opened Outlook 2000 and it checked for email I got the Windows System Message, "DWUSPLAY.EXE has generated errors and will be closed". This raised an eyebrow and I decided to try to find out what DWUSPLAY was. There is no file of that name on my computer. There is no information about DWUSPLAY that I can find on the internet. This message appeared about 4 times whenever I would open Outlook 2000. The message no longer appears. (It stopped on it's own.) Just curious if anyone may know what this may have been??

If you didn't reinstall Windows after replacing the motherboard (I'm assuming you used a different model) then you may get all sorts of weird errors. Back up your data and install a fresh copy of Windows would be my advice....

It was a fresh install of Windows 2000. The only change that may have caused this...as near as I can tell, is the installation of Norton Anti-Virus or something that rode in on an email that Norton did nothing about. *shrug* I use Cloudmark SpamNet to filter out spam mail. Perhaps it was part of a spam email that came in and SpamNet deleted it before the execution completed? Even though my Outlook config forbids .exe content in emails.

It seems, just in case you havent figured it out yet, that this is just SpamNet's auto-update program trying to execute. I dont know what was stopping it on our systems but I am sure that if you make sure it is updated you wont get that message anymore.

Got the same Problem, but I am using WinXP and Norton IS 2003. The Prozess "dwusplay" is started when I start Outlook 2K (with Cloudmark SpamNet), but is not stopped, when I close is (this is weird). Also there is no exe named like this anywhere on my HD. This warning came today firsttime - but I am running Spamnet on exactly the same installation for month now. SpamNet was looking for Updates using the InstallShield updater (agent.exe) all the time. And more curious - no where in the Inet is a thread or discussion about this. Sounds more like a trojan with an altering name to me. Any idea?

I just recieved an error with dwusplay as well. I do not have any new hardware, I have been running XP on my laptop for sometime now. I ALSO run cloudmark spamnet, and when I did a google search on this, this forum was the ONLY hit. Sounds like from what I have read thus far its a spamnet issue. Anyone have any ideas?

I've had the same experiences on two different systems. Definitely seems to be SpamNet, but I've not made any recent changes to either system and both have had successful SpamNet updates in the past. Curious....
