Either something went wrong with zpm or I missed a change in functionality. I have a test zone running zcm11.2.4 which seems to have "lost" the file /opt/novell/zenworks/zpm/signatures/mcescan.cab. DAU bundles also no longer have the step to install this cab file into the zpm folder. Managed devices still have a cab file dated from Dec 17 2013 located in their zpm directory. I checked a 11.2.3 zone and it has the mcescan.cab file located in /opt/novell/zenworks/zpm/signatures with a recent timestamp. Reset patch the option here??
