Error message when executing Certificate Authority Monitor script

Hi all;

I have Windows Server 2008 Enterprise CA. According to this link , when I execute the script by using the following command, I see an error message:

C:\>cscript camonitor.vbs /CAAlive /CACertOK /CACRLOK /KRAOK

I have also installed Microsoft CAPICOM 2.0 . Does this version of the CAPICPM does not supported in Windows Server 2008.If so, which version is compatible?

Thanks
