Hi Michael,
Try the netscape developer site for a bit more info on dde and netscape:
http://developer.netscape.com/docs/manuals/communicator/DDE/abtdde.htm
Ddeexec is used to send an execution string to a DDE server application. So
netscape is basically registering itself to handle http-related requests.
Since netscape is setting up its own parameters, the course of events
"ought" to be renaming ddeexec to ddeexec_backup, followed by creation of
its own ddeexec key.
What happens if an admin runs up netscape, are you still stuck with with no
ddeexec key?
I suspect your non-admin default registry access permissions might be
allowing key rename but not key creation and that's why you end up nowhere.
Regards,
Rick

Subject: [THIN] Default browser and ddeexec_backup
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?
Regards,
