Windows XP Service Pack 2 includes a communications 'Firewall' to protect
your computer from malicious communications. By default, this firewall is
turned on, and so will block all OPC and DCOM communications.

• Completely disable the firewall as follows. Note this can leave your
computer vulnerable to attack so consult your computer documentation or
IT administrator if you are unsure:
a. Open Control Panel followed by Computers.
b. Right click My Computer and select Security Center
c. Select Windows Firewall
d. On the General tab choose option Off
• Alternatively, on the Exceptions tab you can configure specific programs
to permit communications
