I have this EXACT same issue. I have 2 2600 series routers and it's like they are ghosts. You can't add them ass it' says theya re already there. You can't delte them or change them as they don't show up as being there. They are in permanant limbo. I have a TAC case open but my engineeer has blown me off for 2 days now so I don't think it's a good sign.
I have gone as far as running the resoreorigdb perlscript and reset the cmf and rme databses back to empty, But tstill have the same problem.
On one not ethough, I have found this problem only happens when you have incorrect device credentials or don't have reverse DNS for the hostname properly set up.
What makes it weirder is it shows up in RME inventory jobs as a failed evice, but not CMF device repository.
So far my overall impression of LMS 2.5 is don't isntall it if you don't have to yet.It is CHOCK FULL O BUGS.
