"Does not match actual sha1"

I create and upload a task via Windows Software Distribution Wizard like usual, but it shows Error processing completed download because of the sha1 not match. I have checked the file’s sha1 on root server; it is same. Any idea? Thanks.

Last time I troubleshot one of these, there was a proxy server in the way that was replacing the desired file download with an error message. unlikely here, but possible.

I agree that your prefetch command looks well formed and correct, but look at the file size… your sha1.exe shows size of 181 bytes. The file that the BigFix server is downloading is 3194 bytes.
