Does work­ing with third-party ven­dors require you to have the unfor­tu­nate plea­sure of work­ing with IIS 6? Do you need to dis­able SSLv2 and frus­trated by the use­less­ness of Microsoft’s sup­port doc­u­men­ta­tion?

Four sim­ple steps

1. Open regedit.exe (Start Menu > Run > regedit)
2. Nav­i­gate to HKey_Local_Machine > System > CurrentControlSet > Control > SecurityProviders > SCHANNEL > Protocols > SSL 2.0 > Server
3. Right-click on the Server key and choose New > DWORD Value
4. Name the key Enabled with the default value of 0

There is of course a fifth ubiq­ui­tous step when mak­ing Win­dows changes: reboot!
