win2k3 scep problem

hi group

am using IE Vol 1 for Security .. my hardware emulated using Dynamips/PEMU

i have connected a real PC that has win server 2003 to act as a CA server...
however, when i try to get the CA Certificate on the PIX.. i get no response
from the CA

i searched on the internet and found that i have to install an add-on to
enable the scep on win2k3 ... "cepsetup.exe" specifically...

still.. the pix firewall and so the IOS cannot get any response from the
CA... i did packet capture.. found that the pix issue this http command:

GET /certserv/mscep/mscep.dll/operation=GetCACert message=XXXX

however, the response from the server is simply a 404 error.. which is file
not found...

did anybody experienced the same problem before? or did anybody successfuly
managed to work on dynamips and solve the vol 1 labs

please help
