Hi, when I'm trying to setup socket connection to outside world through the ISA server using winsock's blocking connect call, it fails with the error 10050 (WSAENETDOWN). When I try to setup the same connection using telnet or from a Java application it works just fine. The same C program with blocking connect works fine if the connection doesn't have to go through ISA. So I'm thinking I have some socket options set incorrectly... but have no idea what could it be. I would really appreciate any help! TIA -mk
