the network in my office is gone crazy... we use windows 2000 pro w/ SP4 and a couple of windows 2000 servers w/SP4 the thing is, since yesterday there is a problem with the copy and paste and drag and drop of files. i have symantec norton av 2003 installed and updated on all machines. the problem doesn't appear in some of the Windows XP stations we have here. i also ran the House call scan from the TrendMicro site(http://housecall.trendmicro.com/) but it didn't find anything... in some of the workstations (which are Pentium III 633Mhz w/ 128 mb ram) there is an error message that says that there isn't enough memory, although there is nothing running on the workstation. anyone got any idea whats the problem is ?
