BizTalk RFID - Error configuring the Device Manager with RFID devices

If you are getting the following error "ProviderManager did not receive a reply within the configured timeout" when configuring the Device Manager in the RFID Manager - one of the quick checks you want to do is look at the ASP.NET version that is configured in the IIS for that device. If the default is configured to 1.1.x - you want to change it to 2.0.x. and give it a try.
