802.1x authentication

Situation

After upgrading Windows 10 to Windows 10 Anniversary Update (Windows 10 Version 1607), the user sees the erorr:

Error: "802.1X Authentication failed. An RPC error occurred."

The NOVEAP log records messages like

[NOVEAP-0001-LogonUI-C98][15:57:17.482] NwEAPAuthenticate DoRPCConnect NOVEAP RPC server not running. (60 of 60 seconds elapsed)

[NOVEAP-0001-LogonUI-C98][15:57:17.482] NwEAPAuthenticate DoRPCConnect failed completely; error 1715.

Re-registering NOVEAP.DLL resolves the problem.

Resolution

Fixed in Client for Open Enterprise Server 2 SP4 (IR5) or later.

Cause

The Microsoft Windows 10 upgrade process removes the "NovEAP" entry from the "netsvcs" REG_MULTI_SZ value under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Svchost].
