My friend is having some problem with his PC! Every time he starts his PC, LSASS.exe eats up 60% of the Memory... I had the same problem but it got solved when I restarted the PC.. He says he is facing this for a week now.... Any solution??
It is a virus. Use one of the good anti virus programs and a firewall to prevent it. Here is an article I found from a simple Google search that may help http://ask-leo.com/what_are_lsass_l...know_if_im_infected_what_do_i_do_if_i_am.html
It might not be sasser (or smth similar) becuse sasser usualy initiates system shotdown. There are some known issues with lsass on win 2003 server: http://support.microsoft.com/default.aspx?scid=kb;en-us;q308356 Anyway, just to be sure try an online scan!
