About RAS Administration DLL Registry Setup

  • Artikkel

The setup program for a third-party RAS administration DLL must register the DLL with RAS by providing information under the following key in the registry.

HKEY_LOCAL_MACHINE
   SOFTWARE
      Microsoft
         RAS
            AdminDll

To register the DLL, set the following values under this key.

Value name Value data
DisplayName A REG_SZ string that contains the user-friendly display name of the DLL.
DLLPath A REG_SZ string that contains the full path of the DLL.

 

Because RAS supports multiple RAS Administration DLLs, the registry value DLLPath can contain a semi-colon delimited list of paths. For example, the registry entry for a RAS administration DLL from a fictional company named ProElectron, Inc., might be the following:

HKEY_LOCAL_MACHINE
   SOFTWARE
      Microsoft
         RAS
            AdminDll

DisplayName: REG_SZ : ProElectron RAS Admin DLL

DLLPath: REG_SZ : C:\nt\system32\ntwkadm.dll; C:\nt\system32\ntwkadm2.dll

RAS calls the DLLs in the order in which they are listed in this registry value. The registry value DisplayName still contains only a single display name.

The setup program for a RAS administration DLL must also provide remove and uninstall functionality. If a user removes the DLL, the setup program must delete the registry entries for the DLL.

Windows 2000/NT: RAS supports only one RAS Administration DLL, so the registry value DLLPath cannot contain a semi-colon delimited list of paths.
