how could I be sure the download of iAS is correct?

I have been trying to install iAS on Windows 2000 server with a fix IP and

appended domain name. The setup run nicely and said complete. However, there

is no files in the directory after installation. Ray, mentioned that it

could be due to the quality of download.

I have a cable modem here which I reckon has a very stable connection to the

internet. How could I know if the testdrive file I download is in good

condition?

Any assistance is very appreciated. Thanks in advance.
