NetTestPC - method of the Pm object

Test whether the asked PC is accessible in the network.
Boolean NetTestPC(Long nType, String sAddress, Long nTimeout)
nType(Long) Specification of the test method
1 - Ping. The method is functional only if the PROMOTIC process is started within the user's account with the administration rights. If the current logged-in user (in the OS Windows) has no administration rights, then it is possible to start the PROMOTIC process with the administration rights by means of the RunAs program (part of the operating system), for example, by creating shortcut in OS Windows. In this case entering the administration password is required on each starting the PROMOTIC process.
2 - Echo. It's accessible only if the operating system enables the installation of the Echo network service on the target computer. By default it's possible to install this service in OS Windows 2000 and higher as Simple TCP/IP services in the Microsoft network.
3 - Ping 2. The method is functional even if it is started in the context of the user account without administration rights. The implementation of the method is based on the icmp.dll library that is a part of OS Windows.
sAddress(String) network address of the tested PC set by the name (e.g. "\\ASRV\KAFA") or by the IP address (e.g. "")
nTimeout(Long) time in milliseconds for which it's waiting for the response of the target PC. If the response doesn't come during this time, then the method returns the false value.
Return values:
true - The response is returned in the time limit
false - The response isn't returned in the time limit
This method is not functional in Web panels.
