Cannot connect to Windows XP Client remote desktop

[Marcus]

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

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!

Have you tried disabling, hit apply/ok, then reenabling remote desktop? Can
you telnet to 3389?

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?

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.

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.

Marcus:

Did you ever get a solution to this, I am experiencing the same
issues.

Would appreciate if you have an answer.
