Fixed! Remote Desktop Connection (RDC) SLOW/NO Connection Issue

07-21-2007

http://blog.tmcnet.com/blog/tom-keat...lem-solved.asp

In the above-mentioned article, Tom Keating describes how he has found the
issue in Windows Vista which causes Remote Desktop Connection (RDC) to either
fail to connect, or operate extremely slow.

In my experiences, I was trying to connect to Windows 2003 Server and
Windows XP based systems from my Windows Vista (Home Premium) operating
system using RDC. Each time I would try, the connection would stop
completely after opening the window and drawing a small portion of my remote
system's desktop.

After searching the internet for over an hour, I found Mr. Keating's article
and executed the following instructions:

1) Open Command Prompt (START - PROGRAMS - ACCESSORIES - COMMAND PROMPT) as
an Administrator by right-clicking on Command Prompt.

2) Type: netsh interface tcp set global autotuninglevel=disabled

This command disables TCP Auto Tuning which is the cause of this particular
problem. To re-enable it, execute the following:

1) Open Command Prompt (START - PROGRAMS - ACCESSORIES - COMMAND PROMPT) as
an Administrator by right-clicking on Command Prompt.

2) Type: netsh interface tcp set global autotuninglevel=normal

If you're technically savvy, there's much more to this issue (fine tuning
the problem, etc), so I recommend reading this article in Mr. Keating's blog.
But for the layman, this quick fix will solve the problem of not being able
to connect to <Vista Operating Systems.

And to Microsoft - recognize this problem and PUT A SOLUTION IN THE
KNOWLEDGEBASE!

Enjoy and good luck!

when i try to disable the autotuninglevel, it said:
set global command failed on IPv4 The requested operation requires elevation.

i am running as administator.

anyone knows how to solve this problem? i read microsoft's article. i am using Cisco 800 series router (supplied by my cable provider). my RDP session has this problem: when i RDP to my office pc from home, everything is fine; however, when my remote RDP is on (from home) and i come back to office and log into my pc, i get the problem you guys mentioned. The pc only shows small portion of screen. It takes 10 minutes to return the normal state.

I use Vista Ultimate. 32bits Dell PC.

thanks,
Dan

Logon administrator is not good enough. You need to run elevation command
prompt. This link may help.
