Another one of those RDP issues
Posted on 2009-06-29
I have an odd issue. I have 5 servers out of 64 that are sitting on the same subnet/VLAN that I cannot RDP to. The server are HP BL460c blades. They are running Windows 2003 x64 enterprise. They are citrix servers. When trying to connect using mstsc the connection times out and states that "This computer can't connect to the remote computer"
* The VLAN/subnet is not behind a internal firewall.
* Microsoft Firewall service is NOT started.
* 3389 is listing on 0.0.0.0 when doing a netstat -an
* RDP is enabled under the remote tab of system properties
* I have deleted and recreated the RDP-tcp connection under Terminal Services Configuration
* I have completly uninstalled all Cirtrix related software from the server
* NO. I cannot connect via the ICA-tcp connection either
* I have changed the port number for RDP to 80 which did not allow connections either.
* The server does have dual production NICs that are usually teamed. I have unteamed the NICs and just manually IPed one NIC and disabled the secondary
* I have reteamed the NICs using diffrent Teaming algorithems with no luck
* When trying to connect via mstsc I do a netstat -an on the server and see a entry for the remote client computer in the table trying to establish a session via port 3389
* ran microsoft NetMon 3.5 on the server. Can see the server recieveing the RDP connection request and sending a response to the remote client that is trying to connect.
* I get this same issue from multiple desktops, laptops, and servers sitting on the same VLAN and subnet.
* there are no errors in the system or application log.
* IPsec is working fine on the server and I decided to register polstore.dll just to make sure.
I am at the point where I need to get Microsoft support to help, but I wanted to post the issue here first to see if anyone else has run into this issue before. Overall teh server is communicating on the network just fine except for this problem.
