Another reason I hate dealing with MS. I have had this issue with every version of Windows as far back as I can remember so obviously they will never fix the code. So, you want to reconfigure a non-working printer or remove an old entry in the printer server “Ports” tab. But Windows won’t let you – it says that the “Resource is in use.” Huh? I deleted the printer, now I just want to delete the local/TCP port. Turns out there might have been old jobs sticking around and they need to be cleared out first. Uggh.
This isn’t my solution, but I just want to give a shout out to the guy who posted it and hopefully one extra link will give him that much more Google ranking cred.
