Unable to recieve incoming connections (RDP/Terminal/Telnet/ETC)
Posted on 2010-01-13
I have run into a problem with a dell Powervault NF500 running server 2003 storage edition. Earlier this week it stopped accepting connections to it via remote desktop for no apparent reason, and I have been unable to find a solution. The only change that I know we made when this went down was a change of password for our admin account, which should have had no effect on this problem.
It is a server 2003 storage edition dual nic setup. It has the Trend Micro client/server security agent on it. It is browseable and can be pinged by name and on either IP address.
These are the steps I have taken and things I have tried to diagnose this problem.
*Verified that remote is enabled
*Unchecked remote/rebooted, re applied remote/rebooted
*Verified that terminal services is still running with no instances in the event viewer
*Verified that tcp 3389 is listening
*Tried to telnet to 3389 on this server and the connection failed
*Removed the Trend Micro client and tested with telnet and remote desktop. Still failed
*Changed the listening port for terminal services, rebooted, and tested via telnet
*Changed the port back and tried setting the connection in terminal services to each nic individually and tested. Failed on both nics, nic 1, and nic 2.
This server is up and running at the moment, the shares are still active and running fine. I am still unable to remote into it however. I need to get this going for the back-up solution that we use.
I should also note that the rest of our servers are still running fine and able to be remotely administered.
Does anyone have any suggestions or ideas? I will have to try anything that requires a reboot after working hours.
