Networking with a VPC in Windows Vista

Posted in engineering, Microsoft, networking, programming, sharepoint, software, vista, windows by nimad on January 22, 2007

 For my talk at the SF launch I need to do a demo of a client computer calling a SharePoint server.  Since I have one computer to do this on, I have to run the server inside a VPC and install the client software on the host computer.  Then I need to use the Microsoft Loopback Adapter to connect these two.  Here is the details on how to install and configure the Microsoft Loopback Adapter on Windows Vista.

1.       Install the Microsoft Loopback Adapter

Control Panel  à Add Hardware à Click Next on the “Welcome to Add Hardware Wizard”

On the page that comes up click the “Install the hardware that I manually select from a list” button then click Next à Choose Network adapters click Next à Under Manufacturer choose Microsoft Under Network Adapter choose Microsoft Loopback Adapter.  Click Next à Click Next 

 2.Assign a static IP Address to the Microsoft Loopback Adapter

Start à Control Panel à Manage Network Connections à You see a new network registered with a name like “Local Area Connection 2 Unidentified Network Microsoft Loopback Adapter”  à right click it and select Properties à click on TCP/IPv4 à click Properties  à Click use the following IP address à enter (of course the two first numbers are what is important) for the IP Address and for the subnet mask à Click OK.

    I am able to get to the part “Choose Network adapters click Next ” but after that i do not get any list from which to choose from. The system does not do anything – i get a message saying that it is retrieving a list of all devices, but nothing else happens.
    No other button like ‘back’ or cancel works. If i press these i get a message that the Add hardware is not responding.

    Looking forward to hearing from you for a suggestion as to how to proceed. I need to install the loopback adapter.

    I don’t know what is wrong that you are not getting this and I am really not the right person to trouble shoot your system remotely and a blog is not conducive to troubleshooting. I suggest contacting your company support team, trying Microsoft support, trying online forums. Trying this on a different box, possibly with a fresh image or rebooting and retrying.

    Your instructions worked like a charm for me on an Oracle install.

    Great it works. Thank you very much in helping me and I will pass this to my colleagues at school. I am a DBA student and many of my colleagues had failed to get the loopback right. Kudos!

    Hi. Thanks to the above participants. I have a windows 2008 server and I was wanting to install oracle 11g client. The ip address on the ms loop back adaptor shows a limited or no connecitvity and thus the setup gives a network error. Please advice. Installation of ms loop back is same as in vista. Thanks a lot.

    Hello all, I am wondering whether anyone can help me or have some experience with installing SAP ABAP NetWeaver 7.0 where the Microsoft Loopback Adapter is necessary to install – I have Windows Vista.
    I installed the Microsoft Loopback Adapter exactly as described above and after starting the application server following message pops up:

    Error! Connection failed to node (local) for database NSP:
    -24700,ERR_DBMSRV_NOSTART: Could not start DBM server.
    -24701,ERR_EXHNDLR: Could not initialize exception handler.
    -24748,ERR_FILEOPEN: Error opening file C:\sapdb\data\wrk\dbmsrv_DATART-PC.err
    -24826,ERR_NIERROR: Can not open file ‘C:\sapdb\data\wrk\dbmsrv_DATART-PC.err’.

    This design is spectacular! You most certainly know how to keep
    a reader amused. Between your wit and your videos, I was almost moved to start my
    own blog (well, almost…HaHa!) Great job.
    I really loved what you had to say, and more than that, how you presented it.
    Too cool!
