RE: Workflow Maintenance Window taking to long to load.
Hello Romryan,
When you open the Workflow Maintenance Window, GP makes AD calls for every single user you have setup in workflow. It does this for every single step, and every step under those. This means that if you have a hundred steps, with a step under each of those, for just 2 different Workflows (like POs and Purchase Reqs), then you are making basically 500 AD calls the moment you open that window. If you have ANY delay between the SQL server and your AD server, then you need to multiply that delay by 500 to get how long it should take to open the window.
This all said, this is only really a problem when you have lots of steps, lots of users, AND a delay in your AD responses. It can happen with less users if you have a multi-domain setup, which is outlined in detail here:

Hope this explains what you are seeing.
Thanks!
