No, though obsolete browsers like NN4 will not utilise id attributes
properly. They don't implement the document.getElementById method, anyway.

You should test for methods before using them:

var user, password;

if(document.getElementById) {
user = document.getElementById('ftpuser');
password = document.getElementById('pssword');

if(user && password) {
/* Use user.value and password.value */
}
}

See below, though.

The name attribute was designated for backwards-compatibility only on
many elements a long time ago. It acted as a unique identifier;
precisely the purpose of the id attribute. It hasn't been formally
deprecated, though it only applies to certain elements under XHTML
Strict (though it is still present in HTML Strict).

Do not use element minimisation with elements that do not have an EMPTY
content model. This is clearly stated in the Appendix C compatibility
guidelines of XHTML 1.0, and the route of your problems with IE.

Neither the id nor the name attributes are necessary, and your site
should not depend on scripting:

function loadFTP(form) {
var elem = form.elements,
user = elem.ftpuser.value,
pass = elem.pssword.value;

if(user && pass) {
location.href = 'ftp://' + user + ':' + pass + '@os2.no-ip.info';
} else {
alert('Please enter your user name and password.');
}
}

<form action="redirect" onsubmit="loadFTP(this); return false;">

where 'redirect' is a server-side resource that will perform the
redirection in place of the client-side script should it fail to execute.

Using the above, you could remove the id attributes from the INPUT
elements, too.
