Additional Information
Security Consideration for Dell Discovery Utility
When you run Dell Discovery utility on any system, to discover the MD storage arrays, there is a delay of
40-45 seconds to launch the utility if the system does not have access to the internet. The delay occurs
because in the .NET Framework 2.0, when the CLR loads an assembly into a process, if the CLR finds an
Authenticode signature (which involves a Certificate), it generates Publisher Evidence from it and
validates the Certificate by contacting the issuing authority to ensure the Certificate has not been
revoked. When validating the Certificate the operating system scans the chain of Certificates and tries to
download the Certificate Revocation List from a server on the internet. If you do not have internet access
or network is too slow, then this process is delayed - thereby delaying start of the application.
Note: When you disable signature verification, the .NET Framework 2.0 managed application no longer
receives publisher evidence. This behavior affects the .NET Framework 2.0 managed application only
when you use publisher evidence or when you use the PublisherIdentityPermission class.
To avoid the delay in launching the utility on a system without internet access:
1. Open the DellDiscoveryUtility.exe.config file from the location where you have extracted the
contents Dell_MDStorageArray_ABB.exe.
2. Set the value of <generatePublisherEvidence enabled="True"/> to "False".
