System error 86 while mapping c$

Question

Hi, thanks for your time. I'm having the next issue:
I work on a domain network. Usually, we image computers and then join them to a domain.
However, i find it impossible to do anything to an unjoined computer because i get system error 86. Im trying to map c$ from my computer (which is in a domain) with the local administrator credentials from the other computer. The command goes like this:
net use k: \\ipaddress\c$ password /u:localadmin
output:
System error 86 has occurred.
The specified network password is not correct
I have checked many times the local administrator password and im typing it right, i have disabled the firewall, i have run all the services on the computer, and enabled netbios. Nothing works.
The problem is not exactly trying to map c$, i have noticed that once i'm able to map this drive, i can also connect to WMI on this machine from a remote computer. The objective of this is that i'm trying to run a couple of powershell scrits that involve
getting a wmi-object from a remote computer (this doesnt work either because i get ACCESS_DENIED using local admin credentials from  the machine im trying to access.).
Im doing this from a Win7 machine to a XP machine. I've tried XP to XP but it doesnt work either.

OK, I had this problem this morning, and I couldn't find a good answer, including this thread. I'm hoping that giving a thorough answer will help others.
scenario:
You have a computer in a domain (like your work computer). you would like to connect to a workgroup computer and see its files (like your home computer). you cannot browse to the computer and if you try to map the network path you get "system error 86" or system
error 1326". (To map the network path you may try NET USE \\computername\path password /USER:computername\username)
resolution:
To troubleshoot this please try to setup the ideal setup first. Once you have it going you can change to settings you like:
1. disable the workgroup/home computers firewall
you need to do this since both file sharing and kerberos can be stopped by the firewall
2. turn on file sharing on the workgroup/home computer on the network card used
3. create an administrator account on the workgroup/home computer that has the same username AND password as your domain useraccount on the domain computer
4. on your workgroup/home computer, start local security policies secpol.msc and turn on
a) local policies:audit policy: audit account login events: failure
b) security options: Network security: LAN Manager authentication level: Send LM & NTLM - use NTLMv2 session security if negotiated
c) network access:sharing and security model for local accounts : Classic
5. Make sure both computer clocks are showing correctly
Hope this helps
