I found the old thread here: https://discussion.dreamhost.com/thread-134870.html
It’s not directly relevant, as it doesn’t move you much closer to a solution. The key tho is that it seems to require access to the ajaxexplorer server component, and I suspect that in securing webftp dreamhost made that unreachable from outside, other than thru the specific web interface they provide.
You don’t say which flavor of tablet you are using or why ajaxexplorer is important to you. If it’s just because its the same name of dreamhosts webftp client, then find another one, dreamhost webftp has many limitations.
