Seems like rsh is not an option by default within windows 7 enterprise. You can install the Subsystem for UNIX-based Applciations as a feature but that still does not seem to do the trick. All I get after trying it is - "RSH to filer xyz.company.com fails! Quitting."
I've checked my rsh options and the host.equiv file. The rsh is set to legacy. It would appear that everything is fine. So, if you have this working with Windows 7 please document how you got it to work. I'm going to keep digging around for an answer.
The first thing that comes to mind is to install PuTTy or some similar ssh for windows and see how that goes. I would have thought that windows finally would have gotten a secure remote command line shell included by now...
Similar won't work, perfstat.exe on windows expects plink.exe for SSH access. Actually, plink.exe is all that is needed, but it alone does not support passwordless authentication on filer. To setup public key authentication puttygen.exe is needed additionally.
