Hello, we have a Windows 2003 R2 Server (DC) and XP Pro SP3 Clients. On Clients with NOD32 V4.0.474 (standard config) we have problems with copying small files over the network (we have a programm that creates about 500 small files upon loading a project which usually takes about 5 seconds, but on these machines running V4 it takes about 8 to 10 minutes - you cant work with that programm now). I did some research and found this: http://support.microsoft.com/?scid=kb%3Ben-us%3B321098&x=9&y=19 Using xcopy to copy 500 small files to the server takes 2 seconds, but it is slow copying files with the explorer (more then ten minutes). While doing this I get event-id 3019 (MrxSmb) on the client. After uninstall of NOD32 the problem is gone. Disabling realtime scanner makes no difference. I am now using V2.7, still no problem. This is why I am asking for help her: Has anyone else got this problem? Should I open another support case with Eset? Thanks.
