SP2 installed - now unable to RDp

Hi there,

I installed SP2 on a 64bit Windows Server 2003 server. As a result i am
unable to RDP to the server even though the firewall is set to allow RDP.
Even if i switch the forewall off i am unable to RDP. The only way i am
currently getting round this issue is to disable the firewall service (which
is far from ideal!!!).

Can anyone help?

Many thanks in advance

Check the settings on your NIC. SP2 changes some settings that can cause
issues. Specifically:

netsh interface tcp set global autotuning=disabled
netsh interface tcp set global chimney=disabled
netsh interface tcp set global rss=disabled

This turns off RSS, TCP Offload and TCPChimney. You can also do this in the
registry, at:

hklm:/system/currentcontrolset/services/tcpip/parameters.

Charlie,

Many thanks for this, can you tell me what the
hklm:/system/currentcontrolset/services/tcpip/parameters should be as i.e.
name, type and data values?

Many thanks.

Just run the netsh commands - they'll fix it, or should.

For the registry settings, there are three "enable" parameters - set them to
"0" to disable them. They are:
EnableRSS
EnableTCPA
EnableTCPChimney

But the easy way is to run the netsh commands - they set the registry for
you. Once you've done this, reboot the server.

Yep, that did the trick. Many thanks Charlie for your quick response and
helpfulness.
