Hi ...sorry for late reply...

shared drive ?

IIS is using local system or network service accounts for application pool.. so these system users cant ave access to shares ...

thats why u cant run these dlls

shared drive (it is the folder on my server and this application is in that folder)

Is there any way i can run this project from my local machine. I used to do this from my previous machine with out any error. I have changed my computer. Is there any setting i need with my local machine. or a another way around so i can open that project and debug or run it from my local machine without copying it on my Inetpub folder.

I assume that , iis is on your computer..

Create an Account on ur local computer and set the password.. and create the same account with the same password on the  on the share server

then  set this account on ur local  computer in IIS_usrs group

and give read access on the server to the desired folder..
