This is my situation:

HP ProLiant DL140, plenty of RAM and CPU. Win2003 x64 Standard R3, VMware. ZCM (on Win2003 x64) updated to 10.0.2, test workstation updated to 10.0.2. Patch Management active and running, all vulnerabilities downloaded to server. I tried to deploy MS patches but with no success. On my test workstation page -> relationships I see my ZPM assignment but deployment status is red and "Not effective" (at first was pending). I tried to deploy in two ways: scheduled on fixed time and when device refresh (did manual refresh to start deployment) but with no success. After that, vulnerabilities that I wanted to deploy disappeared from vulnerabilities page but test workstation wasn't patched. Any suggestions?
