On October 18, 2016 I posted in this forum about trouble with a small network. The post had many lookers but no responders. Surely there must be someone on the forum who has some input to share. I am trying again to get any help I can get. I have three computers (two laptops and one Desktop) networked through Homegroup. The two laptop computers talk to each other in both directions. The desktop continually denies access asking for credentials or saying I do not have permission. Today was the first time it indicated that I might not have permission because because I have a blank password. I have never had a password on any of these computers. I am the only user and I have no system administrator. There's just me. I recently replace the desktop model because it could not update to the anniversary edition. Installing the new one went beautifully and I had no problem installing my programs and importing my data. But, once again, I have the network and credentials issue. Please somebody point me in a direction of an article or suggest how I may solve this issue. I am getting desperate to overcome this problem. File sharing is turned on, my printer is shared, my C drive is shared. What am I missing? I would appreciate any help. Thank you for listening.
