For these reason, it may be preferable to disable the Process Manager entirely in the Designer interface so that it does not attempt to connect when loaded.How do you disable Process Manager in Workflow Designer?
From the Workflow Designer machine, go to Start > All Programs > Altiris > Workflow Designer > Tools > Edit Local Machine Info.
At the top of the window, highlight "server: (local)" and then click Edit. Scroll to the bottom of the options window and deselect the checkbox for "LogicBase_ProcessManager". Then click OK.
This will require a restart of the Workflow Designer.
