Do you have a firewall on that machine?
Is the 'Allow Remote Administration' enabled.
If you have Windows FIrewall, please run the following on the target...
netsh firewall set service remoteadmin enable
If that isnt the problem, please check to see if DCOM is enabled on the target
Run dcomcnfg, navigate to My Computer node, select Properties and see if DCOM is enabled.
If neither of these are the issue, please send us a email to firstname.lastname@example.org with your availability and we will schedule a online meeting
