It appears that you don't have your ssh keys setup properly for connecting
to indi.mshome.com. Until you can run:
ssh shwetank_at_[hidden] hostname
without it prompting you for a password, you won't be able to boot lam.
I'm not sure why recon would be passing if you are using the same hostfile
-- this is a problem that should cause both recon and lamboot to fail.
Hope this helps,
