You must create an allow rule. One of the following prerequisites is needed to create an allow rule:

• An IP subnet mask 
  Or
• A process name

Example: Subnet 192.168.173.0/24 or process name WUDFHost.exe.

The allow rule will not work if an appropriate IP subnet mask or process name is not provided when you create the rule. For example, suppose that the process name is set to SVCHOST or the IP subnet mask is set to 0.0.0.0. In this case, the allow rule will not work effectively because the configured process name and the IP subnet mask are not accurate. 

To create network rules that WiDi can use when creating the ad hoc wireless network:

NOTE: These rules must be created alongside the existing rules. Do not remove any existing rules.
