router logs DoS attack from a local PC....

Well you did not say that you don't really know what you are doing. It's not a problem of course, but it changes things a little.

It's not even clear if the PC or the router is the problem at this time, so I suggested that you disable some unnecessary things which are usually known to cause many problems, sorry if those were too complicated.

• You could reset some network related stuffz on the PC as a next step. Open an elevated command prompt (run as administrator), and enter the followings on the PC:
  netsh int ip reset reset.log
  netsh int ipv6 reset
  netsh winsock reset
  netsh branchcache reset
  netsh advfirewall reset
  (note: You can export your current firewall rules in the "group policy" before the reset if it's needed for some reason)
  
  
• Btw, Would it be a problem to reset the router to the default settings if the things we are trying will not help? There is a menu point for that called "factory settings" (and also a little hole on the back if you prefer that one).. the Administrator username in the router after the reset would be admin and the password is probably on a sticker at the bottom of the router (special settings needed to go online with your ISP might be also necessary)
  This is not needed now (not yet), but perhaps the source of the problem is at the router and not the PC in question, so we may come to that eventually.

ps.: Do you have a second network card you could test in that PC and a different cable to rule out some hardware issues on the PC side?

Cannot reset pc due to no administrator account, tried different optio

I need help please with a windows 10 pc, I think I messed it up, i think i accidentally deleted administrator account and made a local account but now I cannot reset the pc back to factory because when the window pops up there is only the NO option, the yes option is not there to allow the pc to reset, it says enter a admin username and password, but no box to put it in, I also tried the safe mode with command prompt and typed in "net localgroup administrators (name of admin account) /add and it just says "there is no such global user or group" or "the specified local group does not exist" I just want to reset the pc back to how it was so I can start fresh? Oh I have also tried give admin rights to the local account but when I press apply it says access denied.
Please help me someone, I've had enough now.
Thanks in advance guys
