A number of other people have had this problem. I've attached the file that you should need - it should be extracted into the c:\lighttpd\php directory if you installed the SilverStripe system to the default location.
Usual rules apply - this file shouldn't contain viruses but if it does, I can't be held accountable. I would suggest scanning it just to be sure - I'm using Linux now and so don't run virus scans regularly.
this .dll solves everything i suggest its included when the package is updated
the reason the other one doesn't work is because it was an older version.
I'm also having this issue with dll files. I'm now recieving missing ssleay32.dll. I downloaded the dll and then came up with another error stating "the ordinal 113 could not be located in the dynmaic link library SSLEAY32.dll. Please help!!
The problem with these files is that it never seems to be quite the same between machines. For example, WAMP and Lighty seem to want different versions (even though the PHP version for me was the same). At any rate, try the following file I've attached deeman (no password on this ZIP).
