DisableTaskOffload in my VM and HOST

[SirBrand]

Hi to all and sorry for my English please.

I have a Virtual Server 2005 R2 ENT host, running on W2k3 R2 ENT SP2.
The host emulate 3 virtual machine: ISA 2006, AD, EXCHANGE 2003

I notice some performance issues in my connectivity, the performance are
very poor.

I read this
http://www.markwilson.co.uk/blog/2008/03/problems-with-hyper-v-isa-server-2006-and-tcp-offloading.htm, but I don’t understand something about this:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"EnableTCPA"=dword:00000000
"EnableRSS"=dword:00000000
"DisableTaskOffload"=dword:00000001

Is it a best practice for may case:
- Update these value on ISA (VM GUEST)
- Update these value on PHISICAL HOST
- Update these value on ISA (VM GUEST) and AD (VM GUEST) and
EXCHANGE (VM GUEST)
- Update these value on ISA (VM GUEST) and AD (VM GUEST) and
EXCHANGE (VM GUEST) and PHISICAL HOST

Thanks!

Thanks for your reply but I found this post
http://xpworld.spaces.live.com/blog/cns!3110BDF94643CB31!354.entry were
authors said:
“I was handed the solution: Disable TCP Offloading in the VM in stead of on
the host”

Can you confirm for “Update these value on PHISICAL HOST” only please?

Thank you enough

No, I cannot, but hopefully someone else will answer.
