Randomly happening on login, users are seeing failing to connect to printers. Looking closer, once it fails if I stop and start the print spooler the printers no longer show offline and can print and the printers are there. If I force a policy refresh it happens again and the printers show as offline until i restart the print spooler. Doing a restart usually fixes the issue until it happens again but could randomly happen after the restart. Does anyone have any thoughts. I've been beating my head against the wall with this. We went to Windows 10 1803 and started seeing this.
