Receive-side Scaling (RSS) on Windows 2003 R2 SP2

[chriswu11111]

Hi All

have anyone been able to enable the RSS side of thing on the VMXnet 3 adapter on a Windows 2003 R2 SP2 box within vmware?

I havent had issues with doing this on windows 2008 R2 vmware machine but this option doesnt even appear on a Windows 2003 R2 SP2 machine.

Has anyone had problems with this aswell? any solutions?

I need to use this to speed up our SQL and dynamcs AX application thanks!

We just did this in our AX 4.0 QA environement on an AOS. We have updated our SQL from 2005 to 2008 R2 and Win2008R2 OS in ESXi 4.1.

This is the order we did it in, on an updated (previosly P2V VM) AX QA AOS Windows 2003 server SP1:

KB913184. An RPC client cannot connect to an RPC server that is running Windows Server 2003 SP1.

OK, - Newer version of Rpcrt4.dll installed with SP2.

KB912222 Microsoft Windows Server 2003 Scalable Networking Pack

OK - Installed with SP2.

KB950224 Scalable Networking Pack (SNP) hotfix rollup package is available for Windows Server 2003.

Installed.

KB967723 Security Update.

Reinstalled because of problem with KB950224.

Changed adapter to VMXNET3

Register settings for RSS:

reg add HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0010 /v enable_rss /t REG_SZ /d 1 /f

reg add HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v EnableRSS /t REG_DWORD /d 1 /f

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\0010\ndi\params\enable_rss]

"paramDesc"="Receive Side Scaling"

"default"="1"

"type"="enum"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\0010\ndi\params\enable_rss\enum]

"0"="Disable"

"1"="Enable"

Next step is to enable more TCP features.

What version of AX are you on?
