  • Strange Networking behavior caused by Virtual PC 2007 SP1 ( I think )

    Hi guys,
    this ones really doing my head in so any help is very much appreciated.
    All machines are running XP Prof. I have a host machine and a virtual machine running as a guest using Virtual PC 2007 SP1
    My database server is a VM on a completely different box. I can ping it from my host with no trouble. The trouble begins when I start my guest VM.
    I can sit and watch the network connection go down. From the command prompt I ping with the -t parameter to continue pinging. This runs with no problem until I start the guest VM at which point I get a 'request timed out' message. I get the same message, 'request timed out' when I attempt a 'ping' to the database server from my guest VM. I can ping other machines on the same network from both host and guest.

    It really has me beaten at this point. Please help

    thanks in advance

    What's running on your guest VM? Also, what IP address has been allocated and what 'networking' settings are configured for the guest VM?

      Hi again,
      thanks for your prompt reply. My guest VM has been setup to be my development machine and has the following installed:-
      AVG Anti-virus
      Visual Studio 2008
      IBM U2 Tools - UniObjects and Web Services Developer among others
      TortoiseSVN & AnkhSVN
      Virtual PC 2007

      The ipconfig results are as follows:-
      Ethernet adapter Local Area Connection
      IP Address : 192.168.2.101

      Ethernet adapter Local Area Connection 2
      IP Address : 192.168.2.106

      Networking is set up as follows:-
      Number of network adapters = 2
      Both are using the host machines Networking Controller

      ************************
      I've just fixed it by changing Network Adapter 1 to Shared Networking (NAT).
      It seems in constructing this response I've hit upon the answer so thank you very much for your input.
