How to Wake Up local computer
The computer can be woken up only if it is in the hibernate or standby mode. Please make sure that the power supply should not halt while the computer is hibernated or standing by. If the power is lost, ProfShutdown will be unable to wake up the computer. Please note that if the power supply has been interrupted while the computer was standing by, the unsaved data in active applications could be lost.
Can I use ProfShutdown in peer-to-peer network?
The easiest way to manage computers with Prof Shutdown is to run the program in
a Windows domain. This way, you will not need to make additional settings to the
remote computer – all you have to do is obtain the domain administrator
privileges. If your computer is not a member of a domain, you will need to
provide an administrative user name and password on the program’s prompt.
In Windows XP, unlike in the older versions of Windows, the default
configuration does not allow logging on to administrator account.
To enable it on remote PC:
1. Click Start, click All Programs, point to Accessories, and then click Windows
Explorer.
2. In Windows Explorer, click Folder Options on the Tools menu.
3. Click the View tab, click to clear the Use Simple File Sharing (Recommended)
check box, and then click OK.
How to configure Windows XP Firewall on local PC?
Add processes to the Windows XP Firewall exceptions list: ..\system32\ps.exe
(scheduled mode) and profshutdown.exe (edit mode).
Which protocols and ports does the program use
Program uses SMB protocol, MICROSOFT_DC port (TCP 445) in shutdown, reboot,
hibernate.. mode. In Wake-On-LAN mode uses UDP protocol and port 7 (default
value).
Program can't determine MAC address of remote PC
Remote PC must be accessible over network (power on). Make sure that firewalls
(on local and target PCs) not block program.
Wake-on-LAN Troubleshooting
1. Check up firewall on local PC, it can block a Wake-On-LAN packet.
2. Whether MAC address has been correctly specified?
3. Wake-on-LAN function should be enabled on target PC. Use documentation of the
motherboard and network adapter of target PC. For example troubleshooting
for Intel adapters: http://www.intel.com/support/network/sb/cs-008459.aspx
4. Use the Wake-on-LAN Packet sniffer to test whether a particular machine is receiving wake-up packets.
Is it possible to wakeup (Wake-On-LAN) PC in a different
subnet?
Default value of broadcast address (255.255.255.255) won't work across subnets.
The wakeup packets are not addressed to the client specific IP address is
because most routers will drop the client from their tables if the machine has
been off for a period of time. Once that happens, explicitly addressed packets
would be dropped at the router, but broadcasts to a specific segment will always
get there. If all machines on subnet is down router will drop all packets.
For example, to send wakeup packet from IP 192.168.1.32 to IP 192.168.2.15
broadcast address value should be set to 192.168.2.255 (subnet mask
255.255.255.0).
These values may be determined with Subnet Calculator:
