Issue/Introduction
When attempting to copy large files to an SMB share, the file transfer fails with "Error 0x80090006: Invalid Signature."
Disabling Endpoint Protection (SEP), disabling Intrusion Prevention (IPS), or withdrawing the IPS policy resolves the issue.
Environment
Release : 14.3 RU4
Component : Intrusion Prevention
Resolution
Broadcom is currently investigating this issue. As a workaround, you can disable the Out-of-band Scanning feature within the IPS policy.
