Hi Arkady,

I tried using blocking and non-blocking sockets and the problem still
occur.

Thanks,

Hi Aakady,

We have no special LSP installed (i double checked and view
sporder.exe). It shows the expected LSPs:

MSAFD TCPIP TCP/IP
MSAFD TCPIP UDP/IP
MSAFD TCPIP RAW/IP
RSVP UDP Service provider
RSVP TCP Service provider
MSAFD NetBios....

Thanks,
Yair

Hello,

I have a packet filtering firewall that blocks outgoing connection from
my machine.

I have an application that sends UDP packets. Apparently sendto()
function fails with error code 10004 (A blocking operation was
interrupted by a call to WSACancelBlockingCall).

It happens both on WIN2KSP4 and WIN2K3SP1

1. I am not using blocking hooks at all
2. As far as I understand, sendto() function should send packets and
succeed as soon as they leave the tcpip/ip stack (even the packets are
blocked in lower level by the packet filtering firewall).

Does anyone have any explanation for this behavior?

Thanks,
Yair
