Our users are experiencing an issue in which the APN settings on their Samsung Slates appear to revert to their default values. For example, the APN is supposed to be Telstra.Corp, using an LDAP username and password to connect to our network. This connection is reset by something to Telstra.internet. They're then able to access the internet, but internal resources are obviously not available. Is this a known issue with Windows 8? Is there some way to automatically assign the correct settings?
