SYMPTOMS

After you install the Windows 2000 High Encryption Pack and it appears to succeed, any program that relies on 128-bit security (such as Microsoft Internet Explorer) may still report 56-bit security in use rather than 128-bit after you reboot the computer.

CAUSE

This problem occurs when the administrative account being used to install the encryption pack has a Globally Unique Identifier (GUID) that is longer than 1,024 bytes. The encryption pack Setup program only allocates a 1,024-byte buffer for this value when it is attempting to verify whether or not the user has permissions to run Setup. If the GUID is too long, validation does not succeed and the encryption pack Setup is not run.

With most local administrative accounts, this is not a problem. It currently has only occurred with domain administrator accounts that have been migrated from a Microsoft Windows NT 4.0 domain to a Windows 2000 domain. In this case, the GUID may sometimes be too long.
