In my place of work, every computer from diverse workstation running on diverse operating system namely Windows 7,8 and 10 is connected in a HomeGroup network, my computer runs on windows 10 operating system. All this while i have been enjoying my sharing of files and printing through the network computer until this morning, i needed to pick up a document from a colleague's system but a pop-up from the system is requesting an access password. So i thought i have mistakenly left the homegroup so i went back to join again but couldn't see the join homegroup option, the only option there is to create a homegroup. But every other persons are enjoying their sharing except me. please any suggestion on how to solve this challenge?
