Hi there...

I am having trouble getting VNC to run in vista64. I have it installed
on a few XP systems and a few vista 64 systems.

Everything "works". As I can connect and use it as VNC is ment to be..
but I am having trouble with VNC when installed on the Vista64 boxes.

Basicaly the connection runs "slow". On the XP boxes the screen lag
over the LAN is almost not even noticiable. While on my Vista64 box the
delay in screen draw is so slow it is really hampering my use of these
other remote systesm in the LAN network.

I found this post though google 'Vista Remote Desktop Connection Client
runs slow @ mydigitallife.info'
(http://www.mydigitallife.info/2007/0...4-edition-rdp/)
Witch basicaly says that I have to turn off "Receive Window Auto-Tuning
Level" and "Receive-Side Scaling State" to fix this... I have tried this
with the command "netsh interface tcp set global rss=disabled
autotuninglevel=disabled" but it dose not seam to help.

Dose anyone have any fix for this.

Thanks in advance.

Hi Jyujinkai,

I just want to point out VNC *is not* Vista Remote Desktop so doing
that will not help you at all for VNC and probably make things worse so
undo the AutoTuning and Receive Window settings (Receive-Side Scaling)


Try turning off Differential Compression since XP does not use it...

Click Start and type optionalfeatures.exe into the searchbox and press
enter, then just untick "Remote Differential Compression" then click OK


If your using VNC in a LAN environment this will help but if your using
it over the internet this will not help...Also make sure you have your
manufacturer video card drivers installed on each computer otherwise VNC
will lag regardless

ok... i got that command from the above website.. I assume the command
to ren-enable it is "netsh interface tcp set global rss=enable
autotuninglevel=enable" But i get a error "The parameter is incorrect"

This seamed not to do anything.

I am only interested in using vnc over a LAN, but like i said disabling
that thing did not help. Also I have the latest drivers for my card
installed on the vista64 system.

Vista`s builtin Remote Desktop should work better than VNC in this case


Well basicaly I just use various software that utilized CPU resources
over a network (I do 3D rendering for a living on my home network) So
the second vista64 system is basicaly a render box... so I only really
use it as a remote desktop pumped out to my main workstation as a vnc
window when i wish to load up diffrent software for my workstation to
connect to....

In otherwords I do not need internet remote desktops....

This is all I want so if this other remote desktop thing works fine
then I will just use that.... but i do not know how.

Thanks for your reply

In short, VNC is just slow. Use Remote Desktop instead.

Yes...on sunday I tried to install ultravnc on my notebook (vista home
basic...no rdp) and got disconnected very often. I was testing it in lan
environment!!
So I downloaded Teamviewer....with a completely different result.
