Data transfer to another pc within lan causes cpu usage to go up to 100%

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


thanks very much

 

hi Steve

thanks for responding; that's not the cause unfortunately

i checked and i dont have that key at that exact location; also, i use tuneup utilities and there's an option to search network for scheduled tasks; i double checked and that option is not enabled (i think not enabling it has the same function as the trick that you suggested , right?)

 

several keys

Hi - as i was watching this thread I recalled this same problem with my machine and went to apply the patch, but in the Namespace there are 2 keys, one just like the one Steve posted, and another... Should I disable both?
thanks

 

slow browsing

ok - thanks! Any hints as to what the other key does?
