Q. How can I enable the RAS Dial-in tab on Windows XP computers that run Administration Tools?

Create a registry file called dialin.reg. To do this, open a new file in a text editor such as Notepad, copy and paste the following text in the file, and name it dialin.reg:

Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOTRasDialin.UserAdminExt]@="" [HKEY_CLASSES_ROOTRasDialin.UserAdminExtCLSID]@="{B52C1E50-1DD2-11D1-BC43-00C04FC31FD3}" [HKEY_CLASSES_ROOTRasDialin.UserAdminExt.1]@="" [HKEY_CLASSES_ROOTRasDialin.UserAdminExt.1CLSID]@="{B52C1E50-1DD2-11D1-BC43-00C04FC31FD3}"[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMMCNodeTypes\{19195a5b-6da0-11d0-afd3-00c04fd930c9}ExtensionsNameSpace]"{B52C1E50-1DD2-11D1-BC43-00C04FC31FD3}"="RAS Dialin - User Node Extension"

Merge dialin.reg with your XP registry, or run the following command from the command prompt:

regedit /s dialin.reg

Open a command prompt in XP and type the following commands, where ServerName is a Windows Server 2003 domain controller (DC) that has the Adminpak.msi installed:

cd /d %SystemRoot%System32copy \ServerNameAdmin$System32mprsnap.dll *.*copy \ServerNameAdmin$System32rasuser.dll *.*copy \ServerNameAdmin$System32rtrfiltr.dll *.*regsvr32 rasuser.dll

Click OK to acknowledge the registration of the rasuser library. Your remote XP system should now have the RAS Dial-in tab.
