WM cannot connect to win 7 and WebService

In order to catch up with the trend, I was in the beginning of September in the work of the notebook installed Win 7, recently encountered this let me a few days of one thing, just started to think it is the land bureau here the reason for strict network management. This is the case:

When a mobile phone is connected to a computer with a data cable, the Windows Mobile Device Center automatically detects and establishes a connection so that it can access the WebService service with the port number on a computer, as well as I can access the IIS webservice on the B computer. The most BT is, if I want to connect B computer with the WebService service with port number, one step is to do in the Connection Settings dialog box Click OK, so you can access other computers with the port number of webservice, such as http:// 192.168.1.100:7001/xxx/service?wsdl.

The Connection Settings dialog box is as follows:

Used to sync with ActiveSync, if you want to let the phone and computer data, also is a pop-up dialog box, but it has the "next" button, more clear, now win 7 system but need to find in the hidden location of the Connection Settings dialog box, click OK, feel more trouble.

I wonder if any of my colleagues have the same problem?
