System.out.print("Enter User EIN of System ==>  ");
EIN = sc.next();
System.out.println();

FilePath = "C:\\Users\\" + EIN + "\\Documents\\Sel Test Result\\UserAccess.xls";
fs = new FileInputStream(FilePath);
wb = Workbook.getWorkbook(fs);
sh = wb.getSheet("Sheet1");

int totalNoOfRows = sh.getRows();
EIN1 = readExcel(1,0);
Pwd = readExcel(1,1);

System.out.println(EIN1+" - Login ID for T3");

try
{
  Runtime.getRuntime().exec("taskkill /F /IM IEDriverServer.exe");
}
catch (IOException e)
{
  e.printStackTrace();
}

System.setProperty("webdriver.ie.driver", "C:\\Users\\" + EIN + "\\Documents\\Sel Test Result\\IEDriverServer\\IEDriverServer.exe");
driver = new InternetExplorerDriver();
driver.manage().window().maximize();
baseUrl = "http://bwt05574004.itsm.nat.bt.com:8080/arsys/home";

//baseUrl = "http://itsm.nat.bt.com:8080/arsys";

projectPath = "C:\\Users\\" + EIN + "\\Documents\\Sel Test Result";

driver.navigate().to(baseUrl);
driver.manage().timeouts().implicitlyWait(30L, TimeUnit.SECONDS);

System.out.println("Page Title -- " + driver.getTitle()); // Till Here Working

WaitFor(5000);

WebElement myElement = driver.findElement(By.name("USER"));
myElement.sendKeys(new CharSequence[] { EIN1 });
WebElement myElement1 = driver.findElement(By.name("PASSWORD"));
myElement1.sendKeys(new CharSequence[] { Pwd });code here

Answer 1

Rather than a hard coded 5 second wait, try using WebDriverWait:

WebDriverWait wait = new WebDriverWait(driver,20);
WebElement userField = wait.until(ExpectedConditions.elementToBeClickable(By.name("USER")));

It's entirely possible that the page loads slower on different machines.
