So ever since I installed Windows Vista, I’ve been having problems connecting to our Windows Server 2003 workstation through terminal services. Looks like I finally found an answer to the problem. After connecting to the server, I am able to see the desktop, but the connection typically freezes on this screen for about a minute with the following message:
The connection has been lost. Attempting to reconnect to your session…
Connection attempt: x of 20
Apparently this problem is because Windows Vista has a low initial setting on it’s Auto Tuning feature. What Auto-Tuning does is continually adjusts the TCP/IP receive windows size based on current (and changing) network conditions. It seems that many people have reported problems with auto-tuning causing various network timeout issues with some applications and routers. If you’re experiencing any of these problems, you can turn off Auto Tuning as described below.
Here’s what I did to fix this Remote Desktop Connection problem:
netsh interface tcp set global autotuninglevel=disabledHere’s another version of how to disable auto-tuning as seen on ComputerBits
netsh interface tcp set global autotuninglevel=disabledAnd if you find that disabling auto-tuning doesn’t fix your problem, you can turn it back on as follows:
netsh interface tcp set global autotuninglevel=normalAnd if you’d like to just view the states of your current TCP parameters, you can use this command:
netsh interface tcp show global

1Wanted to drop a ‘thank you’- I work from home, haven’t been able to connect to the office w/my laptop since my Vista upgrade. Surfed around a bit this afternoon to see what I could find. Quick, easy fix, outstanding!

4What was weird is that to some servers (win2k3), it was working fine, and I had no trouble, but certain ones I did.
This fixed the problem. THanks muchly.

7Excellent results here. I’ve been coming very close to removing Vista in favor of XP over this and a couple of other annoying problems. Many thanks. Unfortunately, we remote desktopers will have for forfeit the benefits of Auto Tuning, whatever they might have been.

8I haven’t yet missed out on any “benefits” of having autotuning enabled.
Let me know if you come across anything that is lost by disabling it.

15You know what… this doesn’t work for me either. I think it could either have to do with a networking issue (either at your location, or at the location of the remote computer) or someone has suggested to me that it is due to a lack of resources on the remote computer. Either way, I have not yet found a solution to my problem and I am getting very frustrated.

16For me a similar solution worked, see:
http://www.vesic.org/english/blog/networking/vpn-remote-desktop-vista-and-mtu/#comment-6827
netsh interface ipv4 set subinterface “Wireless Network Connection” mtu=1440 store=persistent
(presuming your wireless interface is called Wireless Network Connection

19Thank you Marcel. It was driving me round the bend. Vista Remote Desktop would work wired connection to XP , but not via Wireless. Changing the MTU size of the wireless connection worked great. This should be a technet article…

23This is the best post I have read all year.
If I had one dollar for every minute I sat waiting out the freeze in remote desktop I’d be rich.
