PSEXEC, access denied errors

Question

While I'm using PSEXEC.exe getting 'Access denied' error for remote systems.

Any idea about how to solve this?

Answer 1

Hi i am placing here a summary from many sources online for various solutions to "access is denied" : most information can be found here (including requirements needed) - sysinternal help

1. as someone mentioned add this reg key, and then restart the computer :

   reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f

   Read this knowledge base article to learn what this does and why it is needed

2. Disable firewall (note - this will leave you with out any firewall protection)

   netsh advfirewall set allprofiles state off

3. if target user has a blank PW and you dont want to add one, run on target:

   [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa] "LimitBlankPasswordUse"=dword:00000000

4. This didnt work for me, but i have read it did for others in a few places, on target execute:

   Start -> Run -> secpol.msc -> Local Policies -> Security Options -> Network Access: Sharing > and security model for local accounts > Classic – local users authenticate as themselves

   if already in 'Classic':

   move to "Guest only - .." run from elevated command prompt gpupdate \force move back to 'Classic - .." again run from elevated command prompt gpupdate \force

5. This one solved my issue:

   run on target from elevated command prompt "net use" look at ouput chart and for shares listed in remote column there (i only deleted the disconnected ones - you can try them all) run "net use [remote path from before list] /delete" then run 'net use \target\Admin$ /user:[user name]' enter prompt password request (if empty PW just press enter), viola should work.

good luck, hope this saves someones time.
