otherwise the only thing i can suggest is changing function discovery provider host and function discovery resource publication to automatic.

that often helps with discovery.
Actually I have already done that. Even created a batch file to run on the computers that were not visible. In what I found "function discovery provider host" was fine when starting automatically but "function discovery resource publication," after starting automatically, in the bat file it had to first be stopped and then restarted for it to do any good. That worked for a little while but then after another MS update or two even that stopped working as intended. Right now they are both set to automatic again but the problem persists.

Thanks for your help.
