Some users may have noticed problems loading this website.

I've been getting 0xc0040034 and FWX_E_SEQ_ACK_MISMATCH on my ISA 2004 Server (Enterprise) on Windows 2003.  IIS/ISA returns 404s on every other request on the published IIS webserver.

Relevent Network layout: DSL --> ISA (not-teamed)--> (teamed)IIS

I suspected that this was due to the network card teaming present on my published IIS box.  I've gone to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, created a DWORD value called DisableTaskOffload, and set it to 1, on both my ISA and my IIS 6.0 box.  This setting did nothing.

I've also tried to change to DISABLE TCP/IP filtering on my gateway/ISA box!  (Properties of the NIC).  Still seems to be doing the same thing =(

ISA 2004's IP Preferences also has any filtering disabled on it now.
