Question : Need help with Get-Contact powershell command

We have about 1200 Contact objects in our AD. I need an Exchange Powershell command (Probably the Get-Contact) to search through all these Contacts and find out which ones are members of a particular Distribution List. I am sure it's something like Get-Contact | where-object...etc.etc. Does anyone have this command available. Like if I want to find out all Contacts that are members of the Distribution Group "All Employees". What would the command be.
Of course, if I have to approach it the other way, like search all DL's where membership contains a certain Contact or group of Contacts, that would work also but it would be more cumbersome because I would have to pass it a list of Contacts. LIke search all DL's and return a list that has any of these Contacts. Easy one for a powershell Guru. We are running Exchange 2007 SP1.

If you are trying to "Lockout" this person, click on the "Account is Disabled" option

The lock out option is for when that user tried to log in 3 times with the incorrect password
