Hi,

My goal is this:
psexec \\* cscript \\server\c$\script\my_script.vbs

It works on the client:
cscript \\server\c$\script\my_script.vbs

But it doesn't work via psexec from server to client:
psexec \\client cscript \\server\c$\script\my_script.vbs

The error message is "Access denied".  I have tried creating a normal windows share but it still says the same thing.  I have even tried adding different permissions, such as allow "Everyone" to have "Full" permissions and it still doesn't work.

Any help would be greatly appreciated.

Does the user account you are running have admin rights on the remote client?  Can you browse \\server\c$ without changing credentials e.g. dir \\server\c$

If not you can specify admin rights on the psexec command:

psexec \\server -u domain\username -p password cscript.exe c:\my_script.vbs

On the client, as the same user I can do this:

dir \\server\c$

And it works fine with no problems.

In fact I can even do the next one too and it works with no problems:

cscript \\server\c$\script\my_script.vbs

Unfortunately I don't know the admin password and haven't logged in as admin for this project.  I created the c:\script folder as the bryan user by typing "md \\server\c$\script" and also "md \\client\c$\script".  I was on the server when I did those commands.

OK.  So you're on the server and can do this:

dir \\client\c$\script\my_script.vbs

But you can't do this:

psexec \\client c:\script\my_script.vbs

correct?

Almost, but not quite.

CAN DO:
on client -> start -> run -> cmd -> dir \\server\c$\script
on client -> start -> run -> cmd -> cscript \\server\c$\script\backup.vbs

*on server -> start -> run -> cmd -> copy c:\script\backup.vbs \\client\c$\script
*on server -> start -> run -> cmd -> psexec \\client c:\script\backup.vbs

CAN'T DO:
on server -> start -> run -> cmd -> psexec \\client \\server\c$\script\backup.vbs

Notice the ones marked with asterisks.  I am copying the file to the client first, then executing the vb script locally.  What I want is to execute the vbscript from a network location.  For some reason it doesn't work.

I have found out a workaround.  If I use the -u and -p options to specify a user name and pass word then I can use the network shares.  I think the program does not allow networking unless one specifies the user name and pass word.<br><br><span style="font-weight: bold;">psexec \\client -<span style="font-style: italic;">u bryan -p 12345 </span>\\server\c$\script\backup.vbs<br><br></span>Is there a way to make it work without specifying the user name and the pass word?<span style="font-weight: bold;"><br></span>

The only other option I can think of is to use the -c option to copy the file to the server before it is executed.

Personally I always copies the file to the server before I execute it to make life easier.
