Can't connect to windows 8 share from any remote source. "The user name or password is incorrect." error

I have a problem sharing my folders on local lan from one Windows 8 machine to.. practically anywhere (tried Android phone and other Windows 8 machine).

As far as I know I do everything right: - When sharing I go to folder's Properties, go to Sharing tab, click Share.... I don't do anything since me (owner) is already set up and I just click (admin)Share.

• I can view this share on local machine by putting \\localhost or \\Ares (name of my computer) in address bar

• My sharing options *Network and Sharing Center * > * Change advanced sharing settings * are as follows:

  • Turn on network discovery
  • Turn on automatic setup of network connected devices
  • Turn on file and printer sharing
  • Allow windows to manage homegroup connections (recommended)

• I do not have homegroup and I'm on a private (home) network. I've already tried this with disabled firewall and I have no other antivirus nor firewall software installed (I'am beyond NAT) and windows Server service is up and running.

Yet still every time I try to connect to this windows 8 shared folder I got login prompt and after typing in ARES\<username> and <password> i got "Incorrect user name or password" error message. I've tried this also on Android phone with similiar result (only there I got connection error message).

I'm not sure if this might be related but it seems that every time I try to access share this error message is being logged in windows Event Logger:

Failed to schedule Software Protection service for re-start at 2013-11-21T19:01:24Z. Error Code: 0x80041316.

Unfortunately I kinda made fool of myself.

I tried to restrict users that are able to login into my computer to just me, and I clicked Select users.... It's was written there that User already has access.

I was thinking.. what user, and then it hit me.

Don't laugh since I've checked this like 3 times, but my username on this computer is not what it's displaying. In control panel it's written that account name is Darnok (local account), but the actual login is User (this is folder name in C:\Users) and also name of actual account.
