From the Microsft Download Center comes this...
"The MDAC 2.7 SP1 Refresh release provides an updated version of MDAC 2.7 SP1 that includes several important bug fixes."
Ok, now go back and read it again, got it.
Now, whatever happened to the increments normally used when releasing new versions of software. Oh wait this is the company that went from a version number, to a year, to another year (with random letters at the same time) then some random letters (now with a year name, released at the same time), then back to random letters again, (with a year version at the same time). If you did not get that then here is goes.
Windows 98 (NT, at the same time)
Window ME (2000, at the same time)
Windows XP (server 2003, at the same time)
Throw in some Windows Bob and Vista, and you really get a nice consistent company.
