  Known issues in running an ISAPI dll via IIS when its not on the C:\ drive Reply Contact Any assistance on this issue thats turned into a head scratcher is greatly appreciated.  I have an ISAPI dll which has been provided to me by a third party. This dll is accessed via a link in the main website like so - mydllfile.dll?var1=value&var2=value. The dll is stored in a separate folder under the website root folder. When the described setup is on the C:\ drive, it all works perfectly but when I have the identical setup, using the same virtual directory (just pointing the D: drive), when I try to access the dll via the link, I get a 400 file not found error.  So on C: it works, but the identical setup on the D: drive fails. I've checked that the C: drive is not hard coded into the dll. Are there any issues known about trying to run dll's that are located on a drive that is not the same one as IIS is installed upon please?
