Naming a Device

Windows CE 3.0

To use the redirector, a Windows CE–based device must have a unique name. The device name can be changed in the Control Panel communications properties, or preconfigured by setting the REG_SZ value under the HKEY_LOCAL_MACHINE\Ident\Name key. The name must include:

  • From 1 to 15 characters.
  • A leading character in the range 'a'-'z' or 'A'-'Z.'
  • The remaining characters in the range 'a'-'z', 'A'-'Z', '0'-'9', or '-.'
    Note   Check with your network administrator to determine a valid name.

The Network Control Panel does not check for invalid names, however the redirector will not function correctly if an invalid name is entered. This restriction also applies to other computer names accessed through the redirector, so servers whose names do not fit the name restrictions mentioned earlier may not be accessible to Windows CE.

This name is registered on the network the first time a file server is accessed over the network using either UNC file operations or WNet functions. The first file operation may take 10-15 seconds while the device name is registered. If the device name is not changed from the default, or if there is an error registering the name, a dialog box appears prompting the user to change the device name and retry the operation.

Once the name has been changed in the Control Panel, any active network connections must be reconnected before the new name is registered on the network. For example, if a network adapter PC Card is used, it must be removed and reinserted before the new name is registered. If an installed network adapter is used, the device must be warm booted for the new name to take effect. Alternatively, with Windows CE version 3.0 or later, the IP helper APIs or ipconfig.exe utility may be used to dynamically restart the network interface via the IP address release/renew functionality. In this case, the card need not be removed nor the device reset.
