Question

How do I change a local user account password remotely using VB.NET/C#?

I have looked into the DirectoryEntry class and know how to add users to a group but cannot figure out how to change a (local) password.

Answer 1

Using .net 3.5:

PrincipalContext context = new PrincipalContext(ContextType.Domain);
UserPrincipal user = UserPrincipal.FindByIdentity(context, "user");

The user can change her own password:

user.ChangePassword("old", "new");

Or, if you run as AD administrator, you can reset it:

user.SetPassword("1234567");
