[Cannot connect to server "Windows"] pop up for no explicable reason

Windows 10 on parallels on mac, Suddenly on startup I get a pop up box that says [there was a problem connecting to server "windows"] and below it the standard server may not exist, check ip etc. But I have NO CLUE what or where this is trying to connect. I have no server with the actual name "windows". I can't think of anything I did differently between before this this message popped up and after. It comes up on startup from sleep or from reset or stop and restart. there is an image in the message of a disk drive looking thing with three silhouette people on a blue background. Seems like I've seen it before but can't place it. I'm betting it's generic but just in case I hunted for it as a logo but didn't find it.
Any ideas on how I can find out what is generating this?

Parallels access does not seem to be running on this device. Worse the Parallels article you referred too said turn off everything else AND disable your firewall. That sound's like it's asking for trouble.

I'll go to that forum but I don't see how you are jumping to the conclusion that this is coming from Parallels? unless you recognize the three silhouettes on a blue background as parallels, which I don't. Trouble shooting 1 is don't jump to conclusions so I have to assume you must recognize that icon?
