Not able to validate credentials

[Sunny45]

Experts,

I am trying to validate credentials on Windows 10 Laptop from a MID server [Windows 2016]. Both are on same network. But I am still unable to validate credentials. I am on Tokyo version . 

1) Firewall is disabled on target host  

2) Ping from MID server OK

3) Telnet from MID to target host OK

4) From  MID server Power shell command ==> gwmi win32_operatingsystem -computer  192.168.1.212  -credential 'svcacct_discovery'   FAILS 

Not sure what is the reason? 

Any other point I should be checking? 

Please advise. 

Thanks.

Is it a local account or a domain account?
When it is a domain account try: <domain>/<user>
When it is a local account, try: ./<user>

Is the account member of the local administrator group?
