Shared folders will not access on Homegroup after format

Hey guys, this one has me stumped.

I have a network of 4 pc's in my house. My main PC that has all my media failed and required a format. After fixing it all, re-joining it to the homegroup I receive this message (pic attached) when trying to access all my media on any other pc on the network. Ive set all security permissions and share permissions that I usually do that lets me use the pc on the network normally. Has anyone seen this? Is there a fix?

Welcome to the forum. Are you using short cuts set before format as they won't work as it's not the same server even if the names the same

Sorry, what do you mean by shortcuts set before format?

The photo looks like your trying to access via short cuts to the drives?

Oh right! No that's just the shared drive files via homegroup on my main media pc, not shortcuts. They show up as per usual as clickable folders, but as I said every time I try to open them now I get that message rather than them actually opening.

Well, i was able to fix my problem. Ill put my results in just in case someone else comes across this message, it may help.

What my issue seemed (?) to be related to was the name of the user account after my format. I had named my pc:

.EXE

I reformatted after my first problem and renamed the pc .EXE and the same problem happened again of being unable to access it on the network.
Upon a third reboot I named the pc Morpheus. And lo and behold all pc's could access the computer again. So it seems to me it was related to the naming of the user account. Maybe the . at the beginning of the named account had something to do with it? Im not sure but im all good now im not using that name. Maybe this helps someone someday!
