Dear experts,

I have installed a Windows 2008 Server which works fine 4 months, but today it make a problem. I loose the connection to the server, when I go personally to its physical location and power it on I see that all is working, but the problem was that the firewall was reset – two ports that have been open are not present – so I make them again and now all is working. More detail - 2 specific ports are lost /allow rule/ and the FTP passive mode - in short all custom settings that I make for this server.

I wonder – how this is possible and what it mean? A problem with hardware, a bug in Windows 2008 server or some attack via Internet? Please share your experience with me … what to check?

The server is with 2 LAN cards – one for WLAN with real IP, second is for LAN access via office – and it provide FTP server and SQL Server. By the way, the problem start while I have been connected to the server with RealVNC and have been working, but not change any settings…

And I wonder – is there better stability with 2008 R2 ?

I'll just comment on the stability:
2008 = vista
2008r2 = win 7

So just based on that, I would defiantly recommend r2.

I'm agree with you, my next servers will be R2.
But the primary question is - do you face with such problems /reset firewall to default/ and this is due to hardware problemm, due to bug or due to attempt for crack /the server is on real IP/

What and where I should check ?

If the network type gets changed from public to private or to domain, each has its own set of firewall rules. Any chance this happened?

Well, this look possible to me ... But it happend due to a bug in 2008, not by me. Actually I was openned the realVNC to both this server and a Virtual machine working on it, but 2 min. I talk via phone with busy hand, so it is sure I do not send any such command ...
