Hello, and --- HELLLLLP!!!! PLEASE!!!!! Just installed Eset Smart Security 4.0.xxx BUSINESS Version latest version, on 4 computers, and on ONE computer (only, others are okay) I cannot change ANY settings, such as "Allow sharing". wHEN I try, a little error msg pops up - "Failed to change settings." Have never seen that error before. This is preventing this computer from being in the domain network. (though computer is getting its proper IP address okay via DHCP) Am running Windows XP Pro SP2, logged in as Administrative user. I have uninstalled & reinstalled ESS several times, same result. Have uninstalled every other previous antivirus, firewall, anti-malware, etc. on that computer. (to prevent conflict -- but now its totally unprotected, & I am desperate to have protection working on here). The only thing I find googling this error message was a couple of people had same problem when using Eset under VISTA 64 bit, with UAC, (but that is not the case here). I have run HijackThis, which finds nothing problematical there. Was previously running NOD32, plus Online Armor firewall, plus did periodic scans with Spybot & etc., so I believe the system to be uninfected. I HOPE SOMEONE HERE CAN PLEASE HELP ME!!!
