After installing your product, my two computers can no longer access each other.

This article applies to: BlackICE Defender.

SUMMARY

Good. This means that hackers anywhere in the world could probably have accessed your machine before you installed the firewall portion of our product.

DETAILS

Microsoft "File and Print Sharing" can be installed in either a "local" mode or a "global" mode. In the "global" mode, anybody anywhere on the Internet can access your machine. Upon installation, the product immediately blocks access to this.

The best solution is to reinstall the option in "local" mode by unbinding from the TCP/IP stack and rebinding to the NetBEUI stack. A good website that explains this is the "ShieldsUp!" site at http://grc.com.

Another solution is to "trust" your internal machines to allow them to bypass the blocking setup by the product. This is described in article q000051.

You can also go to the Protection configuration screen and re-enable "Internet file sharing". This is not recommended, though. If you've shared disks with no passwords, there is nothing the product can do to stop anybody in the world from accessing that share. However, if you enable passwords on that share, the product will warn you of people trying to break in.
