Impersonation when performing IO operation using File.Copy

[Bunty]

Hello,
I am trying to implement impersonation for the copying file from one remote
directory to the other remote drive on the same server in ASP.Net page.

Impersonation seems to be working fine. It seems to perform the
impersonation but when it tries to copy the file then it raises the exception
'Could not find the specified "...."'.

I am sure that the file exists in that folder but still it is raising the
same error everytime.

Here is detail of the complete error

Server Error in '/' Application
--------------------------------------------------------------------------------

Could not find file "\\remotecomputer\C$\Asset\1_4.wmv".
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information about
the error and where it originated in the code.

Hi Bhupendra

Does the impersonated identity hav permissions on
"\\remotecomputer\C$\Asset\1_4.wmv" ?
Cause of "C$" is the identity admin?

Hi Daniel,

Thanks for your reply,

Yes, user does have permission to the specified folder. I am impersonating
domain user which has all the permissions on the folder.

And the error I am getting is not at all is related to the permissions. It
does not find the file at all. And file does exist in that folder but it
still raises "Could not find file'' " error.

Thanks,
Bhupendra

Hi Danial,

I guess I did not read your response very carefully. I did not understand
the what you mean by identity admin?

Actual remote path in my case looks like
'\\remotecomputer\remotefolder1\folder2\folder3' and the error message i am
getting is 'Could not find part of the path "\\remotecomputer\remotefolder" '.

Thanks,
Bhupendra

Bunty..
I have made a similar application and ur error see WIERD!
U said u have impersonated but are u usre the user has access to the
FOLDERS..and is it well shared..
Does the server u are copying the files to have ASPNET acct?
If u can try posting the code u are using..
Hope this helps.
Patrick

 

[Bunty]

Patrick,

Yes, the remote server is also running ASPNET acct. It is also running IIS6
for some other purpose.

Folders on the remote server are well shared and also assigned proper
permissions to the folder and to the domain user (the user I am trying to
impersonate).

Thanks,
Bunty

 

[Patrick Olurotimi Ige]

Bunty...ok then..
But is the error still active?
Patrick

 

[Bunty]

Yes, error is still active and i am trying to figure out the solution for that.
Thanks,
Bhupendra

You need search more info about delegation.
