Cannot Remote Desktop to home PC after installing XP SP3

[Evan Kaye]

I know Remote Desktop isn't strictly speaking "Terminal Services", but it
seemed to be the closest match. After installing Windows XP Service Pack 3
on my home system, I cannot connect to it by Remote Desktop. The client seems
to be trying to connect for a moment, and then automatically cancels less
than a second later, with no error message (whereas I DO get an error if I
try to connect to the wrong machine or port). I have tried connecting from
outside my home network, from another PC on my network over the router's WAN
interface, from the other PC directly to the local network address, and from
the PC in question itself to the WAN interface (it won't let me try to
connect to its own local address); same result every time. Remote Desktop
worked fine before I installed SP3.

I have rebooted my system, disabled and re-enabled Remote Desktop in System
Properties, and added accounts explicitly to those allowed to logon over
Terminal Services using secpol.msc (they were already members of Remote
Desktop Users). I used to connect over a non-standard port for security
reasons, which was mapped to 3389 by the router. I changed it so the
non-standard port is passed straight through the router, and changed the PC's
RDP port in the registry; issue unchanged. Windows Firewall was and is
disabled.

Using Wireshark, I can confirm that the RDP client packets are reaching the
serving PC. If I post the capture here, will someone be able to look into it
and tell me what's wrong?

hey evan,

edit the rdp connection and look on the last register "performance". there
is a option which controls the behaviour when the security constrains are
not met. im from germany so i can't tell you the exact text. the dropdown
box should have selected to something analogous to "connect und don't show a
warning" instead to "do not connect". this is new in the rdp-6.1 client.

Re: Cannot Remote Desktop to home PC after installing XP SP3

Is the PC listening on the rdp port? When you type "netstat -an"
(without the quotes), do you see something like:

Prot. Local address Ext. address Status
TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING

or whatever port you have configured for rdp?

Are there any Events in the EventLog on the PC which can't be
reached?
Are you connecting from a client which runs rdp 6.x? What are the
settings under Advanced - server authentication?

I found the problem. Apparently the latest nVidia drivers break Remote
Desktop unless a registry tweak is made. I'll give it a try and report back
if it doesn't work.

Re: Cannot Remote Desktop to home PC after installing XP SP3

OK, nVidia again, eh?
I would appreciate it if you could post the exact registry key and
the version of the nVidia driver which is causing this problem!

Cannot Remote Desktop to home PC after installing XP SP3- Vera Noest [MVP]

Here's the registry key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]

Edit/create the DWORD Value: "SessionImageSize"
set it to 20 (which equals 32MB).

If that doesn't work, try increasing the size...
20 = 32MB
40 = 64MB
60 = 96MB
80 = 128MB

Thanks, micah! I'll keep that for later reference, I've seen a few
more posts about nvidia drivers causing rdp connections to fail.
