XP Service Pack 2 enables a firewall that prevent local Web Servers from being accessed from other machines. Because SFLM is a Web server, it can not be access by other machines once Service Pack 2 has been installed. To overcome this problem, the following four commands should be issued. SIPC may also have problems so opening its port is also included.

• netsh firewall set portopening proto=tcp port=3162 "SFLM-Standard Floating License Manager"
  
• netsh firewall set portopening proto=udp port=3162 "SFLM-Standard Floating License Manager (UDP)"
  
• netsh firewall set portopening proto=tcp port=111 "ONC/RPC portmap"
  
• netsh firewall set portopening proto=udp port=111 "ONC/RPC portmap (UDP)"
  
• netsh firewall set portopening proto=tcp port=2809 "SIPC-Corba Name Service"

XP Service Pack 2 enables a firewall that prevent local Web Servers from being accessed from other machines. If you wish to be a little more secure and willing to go through some extra hassle, you can enable certain programs to receive messages through the fire wall. Since these programs are versioned, you will have to perform these proceedures again when a version is installed.

• C:\Silvaco\bin\rpc.sflmserverd -WV

  Substitute the number returned for 6.4.2.R below.
