Can no longer access all computers/files/external hard drives

My computers crashed a few days ago - power failure -

when everything was back up, my external hard drives were no longer
visible on one PC in my network/homegroup

the files are still visible in homegroup - I just get an error when trying
to access.

The message reads something like "it appears that everything is properly
set up.. we just can't access the drives"

I tried a "fix" from a post in this forum and it didn't make any difference.

I have left homegroup and rejoined. tried turning firewall off

The same thing happened about a year ago... and i do not remember how
I regained access ;(

I have checked all permissions / sharing settings... just clicked on the folder
again and got this error message:

[Window Title]Open Folder[Content]\\SUPERCOMPUTER\Users\Karen2\Desktop is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.Logon failure: the user has not been granted the requested logon type at this computer.[OK]

I will appreciate assistance as I constantly access the files in these external
hard drives

Hi Bro67.
Sorry... I do not know what you mean?

Thanks Karen

I ran a troubleshooter on the pc that is connected to the
external hard drives.
