@AlanM, ty, ill give it a go.
@JonL even though it isnt applicable to groups since Im using the API Im working around it by dynamically generating the computer name list from a specific group and populating the Action XML via templating so its not much of a big deal. Im not much worried about how long it takes as long as it gets executed against the known list of servers at time of execution. As for those that are missed that can easily be monitored later through checking the last updated timestamp for account passwords. Due to the large volume of servers just getting it done in an automated fashion is more critical than how long it takes, but I get what you are saying.
