If you have very slow access to your network computers through "My network Places" and have already deleted the Registry entry calling for a check of Scheduled Tasks on the other network computers (documented elsewhere on this site) AND you have multiple network adaptors (i.e. a cable or DSL connection through one NIC and an internal network using a second NIC) check the following.

Right click on "My Network Places", go to properties. Right click on the NIC that your cable/DSL connects to, and chose properties. Select Internet Protocol (TCP/IP), and click on properties. Click on "advanced", go to "WINS" tab, and chose Disable NetBios over TCP/IP.

When you are back at your Network Connections page, right click on the Broadband selection, chose "properties" click on the networking tab. Again, chose TCP/IP, properties, advanced, WINS, and select "disable NetBios over TCP/IP"

Worked for me!

BTW, I don't use ICS (can never get it configured right) and instead use Sygate for my Connection Sharing, so I can't verify that with ICS netbios is enabled in the broadband connection and the modem NIC.The Wizard might catch it, but take a look just in case.
