we use cisco vpn client v4 to connect to the office. i installed for myself on my private computer under windows xp and everything worked fine. from some day on (perhaps after intallation of a new program) the machine got 98% busy after starting the vpn client and wont't calm down until i issue the command: net stop cvpnd, only closing the client will not suffice.
i de-installed und re-installed vpn with the latest release and re-run windows setup with option repair and even made up my mind to install sp2 - same situation.
i can easily install vpn e.g. in a virtual machine, where it works fine again, but i cant persuade my real machine to run vpn as it did before.
