I'm running Windows XP, and in my user area the internet connection works fine as does the outlook email. Other users of the pc, with their own user area can still use their outlook, but when using internet explorer they are getting forbidden access.
By the looks of it the pc is stopping those people accessing the web, but i don't know how to change it to run properly.
To change to a user account, access the Control Panel, click User Accounts, select the account to change and then choose the 'change my account type option'. If the users in question only have limited accounts which prevent online access then you can change the settings there.
