IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.

SYMPTOMS
When you try to install a printer, you may receive the following error message:

The printer name you have entered is either an invalid fax printer name or the Microsoft shared fax server is unavailable.



CAUSE
This behavior can occur because the Shared Fax Client does not have a driver in the trusted path. Service Pack 5 (SP5) and Service Pack 6 (SP6) for Windows NT Server version 4.0, Terminal Server Edition make changes to the registry. These changes increase stability by not allowing the installation of printer drivers from untrusted paths.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To install the Small Business Server (SBS) Shared Fax client, you must modify the registry:  Start Registry Editor (Regedt32.exe), and then locate the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Providers\LanMan Print Services\Servers

 Add the following registry value to this registry key:

Value Name: LoadTrustedDrivers

Data Type: REG_DWORD

Value: 0

 Quit Registry Editor, and then restart the server.

After you make this change, administrators can install the SBS Shared Fax client.

After you install the SBS Shared Fax client, you may want to restore the registry to its original settings:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Providers\LanMan Print Services\Servers

Value Name: LoadTrustedDrivers

Data Type: REG_DWORD

Value: 1

Restart the server after you make these changes.
