mount network share over wmic

Question

hostnames: srv1, srv2, srv3

When opening a powershell on srv2, I can mount a remote network drive on srv3 successfully with this command:

PS > hostname
srv2
PS > net use Z: \\srv3\c /user:Admin *
Type the password for \\srv3\c:
The command completed successfully.

However, when wmic'd in from srv1 into srv2 and trying to execute the same command, I get an error:

PS > hostname
srv1
PS > enter-PSSession -ComputerName srv2 -Credential $cred
PS > hostname
srv2
PS > net use Z: \\srv3\c /user:Admin *
net : System error 86 has occurred.
    + CategoryInfo          : NotSpecified: (System error 86 has occurred.:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

The specified network password is not correct.

It doesn't prompt me for a password and I'd like to avoid typing the password out in plaintext.
