Getting Fiddler to work on the CRM 4.0 VPC

After loading Fiddler for the first time on the CRM 4.0 VPC, you'll likely see an error on startup. Fiddler indicates that it cannot listen on port 8888.

Here's how to get Fiddler working on the VPC:

1) Configure Fiddler to listen on port 8889. Then restart the app.

2) Rather than browsing localhost:5555 to load CRM, use this URL instead: http://moss.litwareinc.com:5555/loader.aspx. Fiddler cannot capture requests on localhost but can when the machine name is used instead.

After making those two adjustments you should be all set!
