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 ?
