IE6/7 SSL Problem

[RobWUK]

Hi, We have two Win2003 server with IE7 on. We recently installed an old
app which has broken SSL. One machine Ciper is shown as 0 the other shows as
128Bit but neither are working. Both machines are unable to access SSL sites
- and the vendor has long since gone bust but its and essential account app.

I have reinstalled IE and down graded to 6 on both but hasn;t resolved the
issue. I have used WinStaLE to try and stop what it changing but no luck.

Any ideas what dll or files this could have replaced which is causing it to
stop working following the install?

I have fixed this on our network having tried many many solutions posted here.

I renamed schannel.dll and copied the slightly older version from
Windows\system32\service pack.

Tried regsvr32 but got a entry point errror.

Also reg security.dll and secure32.dll - but error as well.

Rebooted and worked. Have repeated this on two machines.

I then renamed schannel.dll with the orginal version and it still works.

Only connection is schannel.dll is involved in the 128bit cihper.

I can only think a registry entry is somehow getting corrected by this.
