Hi all I have exchange 2000, GFI mail security and GFI mail essentials installed on it, NAV for Exchange, and NAV corporate edition client for file scanning, all the recommended exclusions of the folders and extensions are made (i.e. the inetsrv folder, the .edb, .log..stm, etc.....) I have Windows 2000 SP4, and exchange SP3, all hot fixes are up to date (even October hotfixes all applied on the server) the exchange august post service pack (though irrelevant to this is applied), server is not open relay, behind a hardware firewall. Bottom line how come the server still gets infected with Netsky and other viruses? Thanks for any help
