More on the [link|http://groups.google.com/groups?q=csrss.exe+fix&hl=en&lr=lang_en&ie=UTF-8&selm=%23LEkgOoE%23GA.146%40uppssnewspub04.moswest.msn.net&rnum=4|NT problem]... This one says "The problem is a result of the user running a 16bit app and then disconnecting instead of logging off. To work around the problem you can use the kill.exe from the NT4.0 resource kit to kill the csrss.exe process. this DOES NOT kill it but does keep it
from using 100% of one cpu"
Hmm. 16 bit app. Are you sure that the same version of CA (or whatever you are using) on both machines?
Hope I'm not barking up the wrong tree, here...
