On our HP Compaq Thin Client t5530 machines we are using the installed Internet Explorer 6. We have recently set up the proxy for our location and are requiring that IE go through that proxy.
When IE is first opened it asks for a username, password and domain. This is no problem - I enter it for the particular user of that thin client, click save password and they're all set.
The problem I'm having is that when a thin client is assigned to a different user - we try to avoid this but it has to happen when people leave and new people are hired - I can not find where I can enter the new user's information for the proxy.
