The computer name in the usual natural language is very imprecise, and the following is an accurate description of the registry key associated with it:
--------------------------------------------------------------------------
Windows Registry Editor Version 5.00
The computername at ActiveComputerName corresponds to the current NetBIOS name. Another Place computername will
be copied to activecomputername at the next reboot.
"<Hostname>.<Domain>" corresponds to the current FQDN (full name), "<nv hostname>.<nv domain>" will
Copied to <Hostname>.<Domain> at the next reboot.
Obviously, we have two names, one is NetBIOS name, the other is FQDN, there is no inevitable connection between them,
Although most of the time they are consistent. NetBIOS names can be used in many places for TCP/IP, ipx/spx,
NetBEUI realizes the communication protocol of the NetBIOS interface. The FQDN is only used for the TCP/IP protocol. Microsoft in the name solution
It is difficult for end users to distinguish between NetBIOS names and the number of different names in order to analyze problems.
Fqdn. For example, "ping <name>" what kind of name is used, there will be multiple variants, depending on the operating system, network
Topology, which is not discussed in detail here. In short, remember that when you talk about computer names, there are two kinds of names.
When you modify the computer name on the GUI, the actual action is:
Now you should understand why it is necessary to restart the computer name on the GUI to take effect.
It is generally not recommended to modify these values directly by manipulating the registry, consider the Win32 API. Setcomputername () only
can set NetBIOS name. Setcomputernameex () can be used to set the NetBIOS name or FQDN.
You can also use WMI, as backend has demonstrated. This approach is completely equivalent to the GUI modification method while repairing
The NetBIOS name and FQDN have been changed to take effect after reboot. Note that these two approaches are automatically turned when the NetBIOS name is modified
Instead of uppercase, the FQDN remains case sensitive.
Using Registry Monitor to observe Hostname.exe, you will find that the command takes only the hostname in the FQDN and does not
Takes the NetBIOS name. The "Nbtstat-a <target>" refers to the NetBIOS name. Devmgmt.msc took it.
The NetBIOS name at the ActiveComputerName.
If it destroys the Hkey_local_machine\system\currentcontrolset\control\computername,
View NetBIOS names on my computer, which may be blank. Access to "\\<ip>\ipc$" at this time, there will be errors, Microsoft
The error message given is basically useless. Grab bag found no IP message appears, error level is very high, has not yet arrived
IP layer. Access to "\\<name>\ipc$" can be successful. Flier This kind of thing, it should be to install a software
When you directly manipulate the registry to modify the computer name went awry.
Q: Open Disk Management in XP and report "RPC Service Unavailable".
A:
This is the computer name and activecomputername for the "Logical Disk manager/dmserver" service.
NetBIOS name mismatch, generally because the latter is corrupted. If you are unable to recover after restarting the OS, please
Reset the computer name on the GUI, it should be OK. See:
