JSI Tip 2670. How do I disable password caching for Internet Explorer on Windows NT?

If you are running Internet Explorer versions 4.01 Service Pack 2, 5, or 5.01 for Windows NT 4.0, you can disable password caching by using Regedt32 to navigate to:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionInternet Settings

On the Edit menu, Add Value name DisablePasswordCaching, as a REG_DWORD data type, and set the data value to 1.

If you also wish to disabled password caching for form input boxes (AKA Autocomplete), navigate to:

HKEY_CURRENT_USERSoftwareMicrosoftInternet ExplorerMain

On the Edit menu, Add Value name FormSuggest, as a REG_SZ data type, and set the data value to no.

If you receive an access violation, in Msdaipp.dll, when you open a web page as a web folder, delete the DisablePasswordCaching value name. At a CMD prompt, type net stop "protected storage". IE won't cache passwords if the protected storage service is not started in Windows NT 4.0. If this solves your problem, you can configure the service start up as Manual.
