Guest Marcus Posted August 4, 2008 Posted August 4, 2008 Dear Newsgroup I cannot establish a remote desktop connection on my Windows XP Pro base unit (10.0.1.241) from my Windows XP laptop (10.0.1.242). Connection is an internal one only on 10.0.1.x subnet via router. Windows Firewall has been switched off, checked that port 3389 is listening with netstat -a, RD is swithced on, check that relevant services are running, even moved the RDP port from 3389 to 4489. Ran wireshark to monitor network activity and have noticed lots of TCP checksum error, first 4 packets are good, then errors as below Source Destination Proto Info 10.0.1.242 10.0.1.241 TCP warmspotMgmt > 4489 [sYN] Seq=0 Win=16384 Len=0 MSS=1460 10.0.1.241 10.0.1.242 TCP 4489 > warmspotMgmt [sYN, ACK[ Seq=0 Ack=1 Win=65535 Len = 0 MSS=1460 10.0.1.242 10.0.1.241 TCP warmspotMgmt > 4489 [ACK] Seq=1 Ack=1 Win=17520 Len =0 10.0.1.242 10.0.1.241 TCP warmspotMgmt > 4489 [PSH, ACK] Seq=1 Ack=1 Win=17520, Len = 19 10.0.1.241 10.0.1.242 TCP 4489 > warmspotMgmt [PSH, ACK] Seq=1 Ack=20, Win=65516 [TCP CHECKSUM INCORRECT] 10.0.1.242 10.0.1.241 TCP warmsportMgmt > 4489 [PSH,ACK] Seq=20 Ack=12 Win=17509 Len=428 10.0.1.241 10.0.1.242 TCP 4489 > warmsportMgmt [PSH, ACK] Seq=12 Ack=448 Win=65088 [TCP CHECKSUM INCORRECT] Funny thing when a remove XP SP3 RD worked, but other problems occured which did not relate to RD. So I reinstalled SP3 and once again cannot establish connection. Would be truely grateful from help, lost on this one myself. Many thanks in advance!
Guest Jeff Pitsch Posted August 4, 2008 Posted August 4, 2008 Re: Cannot connect to Windows XP Client remote desktop Have you tried disabling, hit apply/ok, then reenabling remote desktop? Can you telnet to 3389?

Guest Marcus Posted August 4, 2008 Posted August 4, 2008 Re: Cannot connect to Windows XP Client remote desktop Jeff Thank you for your time, I am grateful. I have disabled and re-enabled the remote desktop as you suggested but still no better. Tried "telnet localhost 4489", soon as I press a key connection drops back to command prompt. Interesting if I carry out same procedure on laptop "telnet localhost 3389" the connection is still there when I press a key or sequence of keys. Even when I move RDP back to 3389 on desktop connectio still drops back to command prompt. Could this be something to do with security certificates / encryption?
Guest Jeff Pitsch Posted August 4, 2008 Posted August 4, 2008 Re: Cannot connect to Windows XP Client remote desktop There are security settings that can be set and forced. Is your laptop part of a domain? A level of required security may be set on either side that isn't compatible on the other.

Guest Marcus Posted August 4, 2008 Posted August 4, 2008 Re: Cannot connect to Windows XP Client remote desktop Jeff Neither the laptop or the desktop is part of domain. The network just consists of a cable modem router and two PC's. Once again I am grateful for your time. Regards Marcus

Would appreciate if you have an answer. Colin
