IISREST.exe permission denied

All,
Our unix guys hit my Windows 2003 R2 box via rsh, and when they attempt to run an IISRESET command, they get a permission denied, and a message that states that the user must be a member of the domain admins or local admins.  Other commands work fine.  They log in with a local user that is a member of the local admin ("servername -l servername+username"), and as I mentioned, other commands do work.  Anyone experience this or found a workaround?  Thanks.

It may be a function of how the security token is getting created.
On that machine, for the specific user, was the regpwd command run?
This securely stores the password to the local machine only allowing for a full security token.
(I'm assuming they are doing the 'rsh' login without a password).

no we are not using a password--just using .rhosts with the machine name + username.  I will give the regpwd a shot.  thx.

That did the trick--I had to enable the SETUID option, then do the regpwd, and also had to run the command in a "wrapper," but it got the job done.  Thanks for the help.
