To resolve this problem, use the following methods.

Registry Editor incorrectly. Use Registry Editor at your own risk.

registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan
After you do so, delete the following registry subkeys. These subkeys on a
Windows XP-based computer that does not have SP1 installed may cause the
symptoms that are described earlier in this article:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\25
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\26
To make sure that the Objectname entry is set to the LocalSystem value, and
to back up the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan
registry subkey, follow these steps:
1. Start registry editor.
2. Locate the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan
3. On the File menu, click Export.
4. In the File Name box, type exported rasman key, and then click Save.
5. In the RasMan subkey, locate and then click the ObjectName string
entry.
6. If the value of the ObjectName entry is not set to LocalSystem, click
Modify on the Edit menu.
7. In the Value data box, type LocalSystem, and then click OK.
To delete the 25 and 26 subkeys from the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan registry
subkey, follow these steps:
1. Locate and then click the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\25

1. Click Start, click Run, and then type %windir%\inf.
2. Locate the Sr.inf file, right-click the file, and then click Install.
