could not RDP (remote access) to the win2008 standard server

Hi
I could not RDP to the server 2008 standard few days ago.
netstat -a on the server shoow it listen to 3389.
I disable the firewall manually in control panel  and still could  not access
The server is on the same domain, same subnet. I could access the server such as share folders . Just RDP suddenly not working. I reboot the server and still the same , even with the server firewall off.

I have looked in to some users at this site with the same problem but I have no luck with the server firewall off.

Hi,

Do one thing, telnet your server from where you are accessing it on 3389 port.

Like as follows:

telnet serverip 3389

if it gives blank screen, it means 3389 port is open, otherwise you have to contact your network team to open port 3389.

Hi Peteryau,

Since You are able to listen to 3389, can You try to re-enable RDP on server? Try multiple times because it may not work from frist time. Had same issue on 2008 R2, and after 5th or 6th time it started. Sounds stupid but, it worked. Also I would uninstall any newer updates a day or two before issues started, because it may not work because of them.

Thanks,
D.

1. Have you installed any antivirus and security software's ? If yes, please check that security software settings, is there any thing blocking your RDP.

2. Please check 3389 port is using for RDP only, I mean any application or setting over written port number or any other application is using 3389 port.

Please make sure that 3389 is configured for RDP only.
Please check your registry settings:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
the value should be 3389.

Please check Remote desktop and firewall services running.

terminal services is enabled, telnet server_ip 3389 gives blank screen. ,  RDP_tcp is using 3389, firewall is disable,  it works few days ago and no change in security policy, firewall rules.  
Restart terminal services many times but the same result.

I assume you've already tried RDP using IP address instead of Hostname? Just checking...

Peteryau,

As I said, try to find out from which day in past week or two it stopped working. Than uninstall any windows updates the day before that, or few days before the "day" when it stopped. Restart server and try RDP.

Thanks,
D.
