I have searched high and low and have found no references for this ANYWHERE: I have searched everywhere, including Microsoft Technet and Partners support areas, and the Citrix Knowledgebase and support forums and through Google and Dogpile for this, and haven't found anything even mentioning ddeexec_backup - so we're making history here, people! We have Netscape installed on our servers. Don't ask, it wasn't my idea. Of course Netscape takes over file associations and file types, so I've changed them back with assoc and ftype. In registry, have a look at HKCR\http\shell\open\ddexec\ and \command\ Here's the weird thing: when a USER starts up IE, it RENAMES the ddeexec key as ddeexec_backup, and doesn't create a new key ddeexec. It also creates command_backup, but leaves command there. After this, users can't click on a URL from Word to open a web site. It just sits there and does nothing. There has to be a ddeexec\Topic entry that reads WWW_OpenURL. I've changed the permissions in registry to allow Authenticated Users access to READ these keys, and only Administrator to make changes, and Removed all other users from the Permission list, but it still renames the key. Short of uninstalling Netscape (I'm not sure even that will do it), does anyone have any other suggestions?
