Since I could not find this on the web, I am putting it here for the next person.
When trying to upgrade a virtual server in IIS6 with the FP2002 extensions, I received an error message “unable to access frontpg.lck“.
Since I was logging into the process with an admin account, I needed to add that account to the permissions of the _vti_pvt folder (even if it is just temporary) for write access.
Extending this virtual server solved the problem I was having with not being able to edit an ASP site in Visual InterDev since I moved from Win2K server to Win2003 Server.
