problem with the certutil -crl command

hey

i configured the CA to publish CRL to this location: c:\inetpub\publish\crl

through the certsrv.msc when i do publish the crl are getting publish.

if i run the command: "certutil -crl" i get the error:

CertUtil: -CRL command FAILED: 0x80070057 <WIN32: 87>

CertUtil: Te parameter is incorrect.

but if i run the command like this: "certutil -crl -config "<server name>\<ca name>"

then the crl are being published

what is the cause of this?

thanks for the help
