We are using IIS 8.0 in Windows 8. One of our costumers want to connect to our server by SSLv2 protocol, because it supports an old system.
I have tried to enable SSLv2 in the Registry Editor:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Client]
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server]
"Enabled"=dword:00000001
But it doesn't work. I have tried to enable SSLv2 and to disable the other protocols and it has also failed. When I connect using openSSL:
openssl s_client -connect xxx.xxx.xxx.xxx:443 -ssl2
CONNECTED(00000003)
write:errno=104
Can anyone point us in the right direction to troubleshoot the issue.
