The binaries for 2.0.51 have been removed from the www.apache.org/dist/ site, you can still find them in archive.apache.org/dist/.
However, due to CAN-2004-0811, I would strongly discourage you from using these binaries. I believe it's a disservice to repackage with the patch, since it's ambiguous to the user if they have the original, or patched flavor installed on a given box. The patch referred to is here: http://www.apache.org/dist/httpd/patches/apply_to_2.0.51/CAN-2004-0811.patch I'm prepared to reroll the Win32 installers this week for 2.0.52 - the only question is, what other regressions did 2.0.51 introduce? May as well fix all the newly introduced bugs and roll out 2.0.52 in the next day or two. Bill
