CRM 3.0 Authentication Error

I'm using the CRM 3.0 Laptop client. It works fine while on the network, but when I synchronize with the "Go Offline" button, I get the following error the next time I try to access the information offline:

Microsoft crm could not log you on to the system. Make sure your user record is enabled and that you have been assigned at least one security role. For more information, contact your system administrator.

The synchronization shows as complete and successful. Any thoughts?

Thanks,

Brandon
