Oh, well that makes sense, since they said ICS specifically. Can I recommended termination of the employee who wrote that worst in history KB? You can quote me on that. It's a travesty and makes MS look worse than Syphco or Czechpint. -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Jim Harrison Sent: Thursday, March 22, 2007 8:17 PM To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: You cannot host TCP connections when Receive Side Scaling is enabled in Windows Server 2003 with Service Pack 2 It's only "ISA-specific" because ISA performs NAT on the traffic passing through it. It's new code for WS03 Sp2 that breaks any scenario where traffic crossing the WS03 host gets the NAT hammer applied to it. -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Amy Babinchak Sent: Thursday, March 22, 2007 5:51 PM To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: You cannot host TCP connections when Receive Side Scaling is enabled in Windows Server 2003 with Service Pack 2 I couldn't make heads or tails of any of the RSS documents. There are quite a few of them on MSDN. I'm also hearing that it is hitting SBS Premium users hard. I've been asked if it's an ISA related thing. Since the RSS docs make no sense to me, I have no idea.

I think that this might apply to ISA, but given the SBSoid writing of this article, it's hard to tell. You cannot host TCP connections when Receive Side Scaling is enabled in Windows Server 2003 with Service Pack 2: http://support.microsoft.com/default.aspx?scid=kb;EN-US;927695 "SYMPTOMS You cannot host Transmission Control Protocol (TCP) connections when Receive Side Scaling is enabled in Microsoft Windows Server 2003 with Service Pack 2 (SP2). The TCP connections are reset. This problem occurs if you use Network Address Translation (NAT) and if the host computer is configured to be an Internet Connection Sharing host server computer." First, what does it mean to "host" TCP connections? Does it mean "terminate" connection? Does it mean something else? Second, "if you use a NAT" NAT where? In front of the box? Behind the box? On the box? At Tim's house? Third "if the host computer is configured to be an Internet Connection Sharing host server computer" Does this apply ONLY to ICS? What about RRAS NAT? What about ISA NAT? Someone needs to tell these guys that we really don't live in their heads, even though they might hear voices. ;) Thanks! Tom All mail to and from this domain is GFI-scanned.
