Hi, I struggled with the same problem, and
found that you need to copy the file from \php\phpts.dll to c:\windows\system\
If you are loading modules, remember to edit php.ini in the [path] section. extension_dir="c:\php\extensions\"
I had lots of probs. setting up domxml ext., and if you are interested, then take a look at my site at: www.mdz.dk
