Hi,
I use Cisco VPN Client version 5 on Windows XP computer. I uninstall the vpn client, reinstall and it works fine until I reboot and then I get this error message, when trying to connect through Cisco VPN as below :

how do you do thois on win7 ? VPN Error 5 : No hostname exists for this connection entry. Unable to make VPN connection
If this issue on win7: go to one of your co worker laptop and C drive, program file, cisco system, vpn client, profiles, Pcf File............now you need to copy that to your jump drive, go into to your computer and go through as above, then delete your Pcf File then paste the pcf file from jump drive over. restart the computer.
I have found some information about this error that can occur in the case of Cisco VPN client crashing or the system restating unexpectedly when the client is connected to the local host. So to solve this issue, one needs to keep backup of the copies of the .pcf files ot update the pcf file if it is broken with similar information from another pcf file. If that doesnt work then one could also deploy a script file written in VBS or scripting language of any choice of the user and run this at the startup on the machine, that will compare the file size of the this current pcf file, and it will also replace it with a known good file, if it is not the correct file.
