I'm looking for a way to change the password for some user of a Windows box remotely from a Linux Box. Really I have to do it by running some program/system script on the Linux Box but without running anything more than standard services on the windows system.

Really it is a programming question, but SO people closed it as not "programming related" so I guess it belongs to ServerFault. I write that to avoid being sent back to SO. – kriss Jun 6 '11 at 22:05
So is a windows box or linux box? Your title and body say two different things. – EEAA Jun 6 '11 at 22:08
The Question on SO has been edited to be more programming related, but I'm still interrested by means to do that using shell tools on Linux. – kriss Jun 6 '11 at 22:23
@Erika: I'm running my script on Linux and the password of a remote Windows box should be changed. – kriss Jun 6 '11 at 22:24

You can update the "unicodePwd" attribute of the user object using LDAP over SSL to reset a user's password. This is probably the most straightforward "cross-platform friendly" way to make such a change because, on the Linux site, you won't need any MSRPC infrastructure.

Interesting, but the asker doesn't say whether this machine is joined to a domain or not. – gravyface Jun 7 '11 at 1:12
@gravyface: Good point. I'm so used to living in Active Directory environments that I can't imagine not having one. Definitely a good point. – Evan Anderson Jun 7 '11 at 2:42
Andersan: I should have said I already did that for machines that are in a domain, I'm looking for another solution for stand alone machines that are not inside a domain. But +1 anyway as I totally agree it's the best solution. – kriss Jun 7 '11 at 8:02

I am somewhat in doubt about what you are going to accomplish - changing a Windows user's password? By script?

If so, take a look into winexe - it uses RPC calls and allows you to run commands on the Windows machine without prior software installation (the Windows firewall must be configured for letting RPC through, tough). Running a net user <username> <password> on the Windows machine would do.

Thanks for the link. I was looking for something using the SMB API, but winexe could indeed another way to do it. – kriss Jun 6 '11 at 22:27
That would be really a SO question. But you always can take winexe's source code and incorporate it into your project to run a command. In theory, you should be able to use RPC for changing the SAM account information directly - I do not know if Samba's rpcclient would support that. – the-wabbit Jun 6 '11 at 22:48
