I am trying to run sysinternals' PSEXEC from my domain machine to workgroup machine and vice versa:

Cmd Line:

Psexec \\\MachineName -u "username" -p "password" -i -s -d cmd.exe
  • If I run this command from a workgroup machine to a domain machine, sometimes it works fine and sometimes it fails
  • workgroup to workgroup: fails
  • domain to wokrgroup: fails

I get this message stating the reason for the failure: Access denied with OpenSCManager. I know that PSEXEC uses OpenSCManager, but I'm not able to figure out the reason behind the denied access.

My settings:

  • administrator account on both the workgroup and domain machine
  • command prompt in administrator mode
  • Firewall is off
  • Network sharing is ON

PSEXEC does not give an invalid username/password error; I've also checked that the credentials are correct using net use.

Please help me with some info regarding whether this kind of access is allowed/feasible or not.

  • One may like this or not, the solution is luckily pretty simple. UAC remote restrictions can be disabled by setting the registry value LocalAccountTokenFilterPolicy to 1: Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System Value: LocalAccountTokenFilterPolicy Data: 1 (to disable, 0 enables filtering) Type: REG_DWORD (32-bit)
