SYMPTOMS
In Microsoft Virtual PC for Mac Version 7, you may experience poor network performance or Internet access issues.



CAUSE
This problem may occur when you run third-party firewall software on your computer. The Virtual PC for Mac Version 7 program connects to your local network or to the Internet by using either the ethernet network connection or the Airport network connection on your Macintosh computer. Third-party firewall software may interfere with this connection and cause reduced network performance and Internet access issues.



WORKAROUND
To work around this problem, you must switch to the built-in firewall in Mac OS X. To do this, follow these steps:
 * 1) Disable and then exit your third-party firewall software.
 * 2) On the Apple menu, click System Preferences.
 * 3) Under Internet & Network, click Sharing.
 * 4) Click the Firewall tab, and then click Start.
 * 5) Close the System Preferences window.
