Windows 2003 SP2 beta testers just received notice that 'SP2 RC - Refresh 1' is available on Microsoft Connect. The build number is 2845, and the x86 download weighs in at 370MB.
Refresh 1 isn't widely available (public SP2 RC link) - unless you have access to SP2 on Connect you're out of luck. However, from the brief change log I saw, Refresh 1 is simply a bug fix release.
