Publishing CRLs

Hi,

Many guides point to publishing CRLs on web servers that are NOT the Subordinate CA's IIS. So if we use another web (IIS) server, and in the CDP and AIA point to, for example,http://anotherIISserver/... how does the CRL/CRT actually get there? Do we have to manually copy it across everytime?

I mean, if its published on the Subordinate CA's IIS, then the IIS virtual directory already points to the /CertEnroll folder...so how does it work if the IIS server is on another computer and not the Subordinate CA?

thanks,

SK
