I need help due a my silly mistake!

So for long time i have a dedicate server hosted by register.it

Usually i access remotly to this server (Windows 2008 server) by Terminal Server. Today i wanted to block one site that continually send request to my server.

So i was adding a new rule in the firewall (the native firewall on windows 2008 server), as i did many time, but this time, probably i was sleeping with my brain i add a general rules that stop everything!

So i cant access to the server anymore, as no any users can browse the sites, nothing is working because this rule block everything.

I know that is a silly mistake, no need to tell me :) so please what i can do ?

The only 1 thing that my provider let me is reboot the server by his control panel, but this not help me in any way because the firewall block me again.

i have administrator username and password, so what i really can do ?

there are some trick some tecnique, some expert guru that can help me in this very bad situation ?

UPDATE i follow the Tony suggest and i did a NMAP to check if some ports are open but look like all closed:

Question: The provider locally can access by username and password ?

If you can't get in remotely you will have to get your provider to fix the problem for you by connecting locally.

  • @lain That's clear and evident and thanks for your answer, i was thinking if exist some that i can do by have the administrator privilege in hand. There are backdoor ? vulnerability ? something that i can do ? poor me really ;(

  • Not likely to work but you could do an nmap scan against it to see what holes are open. If you hoster can't help this may be your only chance. but on the other hand if you really did shut down all ports then this might not work! I'd hire a hacker to see what they could do...

Your provider does not provide remote console access to its servers. This means your only option is to request that they reinstall the operating system. Once it is reinstalled, you can restore from your backups.

You may wish to shop for another server provider who offers remote console access to their servers.


Not so much an answer as a suggestion for the future.

Have some sort of additional way into your machine. IE: LogMeIn, TeamViewer, VNC, anything that causes the connection to established out from the server to the interent should prevent firewall mistakes like this one from preventing your access.

  • yes i accept your suggestion for the future, this mistake teach me well
