FP98: FrontPage Appears to Hang When You Use Dial-Up-AdapterID: Q194237 
  | 
When you use a Dial-Up-Adapter to connect to the Internet and you are not currently connected, your computer may appear to hang (stop responding) when you use FrontPage Explorer or FrontPage TCP/IP Test.
If you are using DNS for name resolution, any call to the TCP/IP stack will attempt to resolve to an IP address. If you are not connected to your Internet service provider, there is no DNS server available. The computer will attempt to wait until a DNS server replies.
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
To work around this problem, follow these steps:
      127.0.0.1       <fqdn> 
   where <fqdn> is the Fully Qualified Domain Name as specified on the
   DNS Configuration tab of the TCP/IP Properties tab (double-click
   the Network icon in Windows Control Panel). For example, if the Host is
   named Mycomputer and the Domain is called Mynetwork.com, you would add
   the following line to the Hosts file:
      127.0.0.1       mycomputer.mynetwork.com Additional query words: Front Page lock up freeze crash
