If Vista users using firefox 2.0.0.3 are having problems with a website you are running on an older Linux server, upgrading the kernel from a 2.4.xx to a 2.6.xx kernel will fix the problem.

Forgive a newbie, but if we've got one application in particular giving us trouble, is there something less 'global' than "netsh interface tcp set global autotuninglevel=disabled"?

I tried it, and it fixed my problem. (My problem was with Subversion.) However, everything else seems to be working fine. Am I fooling myself? If not, can I turn off autotuning for a particular application or for particular destinations/ports?

We were having problems connecting to servers with RDP during a Remote Web Workplace session. The RDP logon screen would hang. This only happened when our Vista laptops were connected to the domain either on the local network or with VPN. Disabling TCP autotuning did the trick:

netsh interface tcp set global autotuning=disabled

Hi, regarding the note about IE7 using highly restricted autolevel. How can I force my application to to do the same without changing global tcp stack settings ?

For application developers:

use SIO_SET_COMPATIBILITY_MODE option of

WSAIoctl function.

Is there any way that we can get rather more help from Microsoft on this disastrous issue?

Wishlist

i) a comprehensive test tool to definitively identify this specific issue in routers, with very detailed reporting,

ii) MS to help build up a definitive list of known good/bad router firmware versions, to save us all having to repeat the same tests,

and

iii) using Microsoft's might to put pressure on specific router manufacturers to get timely firmware fixes? (most important of all)

Ran into this issue on a network of Windows 2000 servers, and one Server 2008. Workstations had some wild network browsing issues, extreme delays, some freeze ups for 5 minutes at a time with auto tuning enabled.

Hi,

how is Auto-Tuning technically working? The Cabel Guy Article is not very informative. When is Auto-Tuning done? Only at the beginning of a TCP (SYN) connection or while the connection?

How is it realized (TCP Header Window-Field)? If the RWND is not dynamicly tuned while connectionis established is just a TCP Scaling Option thats working per-connection an not set globally.

Questions and more questions.

Mark

I'm experiencing extremely slow performance when using the subversion repository over a network drive. Normally accessing the drive is fine, but checking out a small project can take several hours. Unfortunaly this tip made no difference. I see several other people with this problem but have found no solution.

Try disabling rss also for the person having the subversion problem.

I had the same problem and that fixed it.
