Automatic recognition of LAN - wrongly (3.9.81003.508)

CIS recognizes the LAN wrongly, see image:

Instead of /, CIS puts / or something similar. It happened with almost every installation. This leads to many unnecessary pop-ups regarding LAN requests and problems in file and printer sharing.

Network: plain & simple home network
Version: 3.9.81003.508 ( also in 3.8 )
reproducible on Vista SP1 and Windows 7RC
