Make sure that the default admin$ share is enable on ServerName

Question

When running the psexec command to remotely install or execute something on a sever on the same network the following error was displayed.

Couldn\'t access Serve

Answer 1

In my case it was a network problem like mentioned in the error message.

I needed to allow SMB traffic on port 445 on the target machine. PSExec worked straight away after adding the firewall rule to allow that traffic.
