hi, i recently have had a weird problem with my lan connection on a particular pc

when i transfer files (copy or move) out to another pc within the lan, cpu usage goes up big time, but incoming data transfer doesnt seem to cause that high cpu problem; data transfer among HD's within the pc is normal until it's going out of the pc (regardless of which hd is coming out)

all my pcs ar on win2k pro; this particular pc is a p4 3.2 ghz prescott, mobo is asus p4p800se with onboard gigabit nic from marvel; i have a pretty fast cable connection but i have no issue with internet speed; i'm just trying to figure out what causes the bottleneck that causes cpu usage to max out and make all other tasks temporarily frozen

i tried upgrading from the etherfast switch to a gigabit switch but no difference; i tried adding a second adapter while the onboard nic is still enabled, no difference; thinking may be it's the nic going south, i bought a netgear gigabit nic and disabled the onboard nic but still the same problem;

please advise as this is really bugging me; it used to not have this problem before; just started recently

oh, and when cpu peaks while transferring data out, i look at the processes through process explorer, these 2 processes are the main culprit (explorer.exe and DPCs) and at times system process as well


thanks very much

hi virtualme,

thanks for responding; when u say corrupt file, u r referring to the files being transferred right? or r u referring to some other corrupt system files? b/c my situation is not any particular file, it's just data outflow that causes high cpu, not even big files, even 50MB file size would make it peak for a few seconds; i havent tested its speed to see if it's up to par but that's less of a concern for me than its cpu hogging behavior

i run lavasoft adaware and spybot S&D, kaspersky antivirus, protowall, have the most recent ms updates; i dont know what else i can check

i was looking for a setting in the nic that would alleviate the load on the cpu but cant seem to find it; may be the netgear gigabit nic and the marvel onboard nic dont have that feature

The way I read it was a file in the folder he was trying to transfer, but it is possible it could be any file.

I easily located the corrupt avi file with the process mentioned in the above post (btw, the filename was preceded by TMP in case that is a flag).
