Hi Mostafa,

TCP 135 is used by Secure Exchange RPC publishing. The PIX isn't an intelligent firewall, so it does not know how to manage the RPC communications securely, move the PIX out of the way if you want to use Secure Exchange RPC publishing.

RPC/HTTP does not use TCP 135, it uses SSL, TCP 443.

HTH,
Tom
