I seem to be getting this error everytime I log into my work domain on a windows 7 machine... When I got a dedupe error when logging on with a windows XP machine in the past i took these steps to resolve issue 1. added [My work domain]\Domain Admins group membership to the local (Users) group 2. Added [My work domain]\Domain Users group membership to the local (Administrators) group Restarted then re-logged in and all is well!!! Firstly I get this error message 'Deduplication COM Server has stopped working' then the error message in the title after I close the first error!!! Can anyone advise as to why I get this problem and how to fix it..? I have searched TechNet and googled but there is very little information regarding the dedupe error. Please help!! Kind regards, Adge

Hi Adge, When the issue occurred? Have you installed any software or update recently? I notice DeDupe is a duplicate file finder designed to analyze duplicate files and increase the hard disk space. It deletes duplicate files and compresses into a zip file. If you are using this program, I suggest perform a Clean Boot to check the result. http://support.microsoft.com/kb/929135 Also, please contact domain admin to check the issue.

Hi Niki, Firstly thank you for your reply and support I very much appreciate your time. Secondly, I have already taken steps as set out in KB929135 (apologies for not advising in the first instance). But even after these steps I still get the error, even when all start up items and non windows services are disabled! Error detailed below.
