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
 
Re: SP2 installed - now unable to RDp

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.

Re: SP2 installed - now unable to RDp

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.
