Problem in installin SAP Netweaver Sneak Preview

Question

While trying to install the SAP netweaver sneak preview I got this error at the second step of the installation “SAP System installation”…..
"An error occured while processing service sneak preview edition of SAP web application server java 6.4  install sap web application server java 6.4
you may now
press retry to repeat the current step.
press view log to get more information.
stop the task and continue with it later.
reset your input for the current task .in this case SAPinsti will permenantely remove all installation files from the installation directory. This gives you the oppurtunity to start from scratch."
Can someone kindly guide me as to what to do..
(1)when I pressed retry I again got the same screen.
(2)when I pressed reset and again started from scratch I again got the same error.
(3)the view log shows
“ERROR 2005-12-27 11:06:09
CJS-00081  Assertion failed: in function () {    var changed = false;    var nodeName = (new NetworkMgt()).getServicesFileName();    var mgt = new FileMgt();    var node = mgt.getNode(nodeName, true);    ASSERT_DEFINED(arguments.callee, node, "node(" + nodeName + ")");    node.saveVersion();    for (var it = this.getInstances(); !it.isDone(); it.next()) {        var instance = it.get();        if (instance.installInstance()) {            changed = instance.createPorts() || changed;        }    }    installer.writeInfo("ind-rel.ind-os.ind-db.j2ee-eng.creatingPorts", this.getSID());    if (this.j2eeStandalone) {        var port = this.getSCSMSPort();        if (port) {            changed = WebAS.createPort("sapms" + this.getSID(), "tcp", port, "# SAP System Message Port", true) || changed;        }    }    if (!changed) {        node.revertVersion();    }}Variable node(C:/WINDOWS/system32/drivers/etc/services) should be defined”

Hi,
Try the installation after starting all the services of the DB. For example if you have used Oracle as the underlying DB, make sure that the important Oracle Services like OracleOraHome92Agent, OracleOraHome92TNSListener and OracleServiceJ2E are in Started status.
If some other DB, start its services. To start the services go to start - Settings - control Panel - Administrative Tools - Services.
