After the first success, I hit Ctrl+ C and run the prompt again

smbexec_windows.exe -hashes :ae···························· rootkit/[email protected]

How can I solve this problem and hope for an early reply

@PolarPeak I cann't build it in linux , what is your host os ?

[PolarPeak]

Windows 10
I have already known the problem. I can log in to the server of the other party through RDP and delete the output file under disk C

I get also this message when running smbexec against the target!
Have anybody found the solution?

the message says that the service exists! does the service exist on the kali box or on the target box? and which service is concerned?

[Zinou16]

I've found what the problem was.
The service causing the issue is running on the target machine. it's the "BTOBTO" service, created by the smbexec.py script.

From my understanding, this service shouldn't be permanent on the target machine. But for some reason, it was there!

To fix this issue remove this service using the following command:
"sc delete BTOBTO". then restart the system.

Wanted to give an update to anyone having the same problem. As mentioned above "BTOBTO" is the default service name created. If it already exists then you can not use it again. If you use the -service-name argument you can supply your own service name, you can bypass the error. Example: smbexec.py domain.local/username:[email protected] -service-name 123abc
