Hello, I Installed the free FortiClient-Lite AV v5 on WinXP SP3 with the Novell Client v4.91 SP5 on an old work laptop.

FortiClient has replaced the Novell GINA (a.k.a. Logon screen) with Microsoft's by deleting the following registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]

I restored this successfully, but my Lock screen has remained as Microsoft's instead of the Novell Client's "Workstation Locked" screen? My Network Connections > Advanced Settings > Provider Order has remained the same (NetWare Services at the top).

I experience a new delay showing my Windows desktop after logon, but this was probably due to pre-existing XP quirks that FortiClient's changes exposed. Otherwise, FortiClient is a nice AV, with Parental Controls via web-filtering categories plus AV swinging it for me.
