I started hearing of printing problems with network printers (hp laser jets) pages would not print or they would print after a couple of minutes. In conjunction with this users started geting kicked out of a database program we use. Also sporatic problems with email and slow browsing. I have symantec corporate 11 with definitions as of sunday on all the machines.
Some things I have found.
Maped network drives are not available unless browsed to.
Printers will print if I set up an extended ping and then try to print.
I am getting active directory/DNS errors but I print to my hps using tcp/ip with a ip address so I don't understand why they dont print.
Sounds like its viral or spyware related but my pc's show no infections. Any ideas. I have wireshark but I realy don't know what I am looking at.
