Accessing a WorkGroup Computer from Domain Member Computer

I have a computer named Windows7 that I am trying to connect to it from a Domain member computer using UNC path \\IPaddress\C$
I get the pop window to enter credentials. I type in Windows7\Myadmin then password for Myadmin , but I cannot connect.
If I go to Windows7 computer I type Myadmin  and Password then I can login.
Also, From Windows7{Workgroup} i can connect to the Domain Member computer using UNC path \\Computer\C$.
I get a popup for username and password.. I type in \\DomainName\Username then password.

I am not sure what could be the issue.

Any help will be appreciated.
Thank you

Hi there! :)

You need to create a trust first. You may refer to the following instructions as a guide.


  1. Open the Active Directory Domains and Trusts snap-in.
  2. In the left pane, right-click the domain you want to add a trust for, and select Properties.
  3. Click on the Trusts tab.
  4. Click the New Trust button.
  5. After the New Trust Wizard opens, click Next.
  6. Type the DNS name of the AD domain and click Next.
  7. Assuming the AD domain was resolvable via DNS, the next screen will ask for the Direction of Trust. Select Two-way and click Next.
  8. For the Outgoing Trust Properties, select all resources to be authenticated and click Next.
  9. Enter and retype the trust password and click Next.
  10. Click Next twice.

the computername must be windows7
and the user myadmin must be a member of the administrators group to access c$

net use * \\windows7\c$ /user:windows7\myadmin /savecred

Open in new window

when requested type in the password
the share should populate with the drive letter coming down from Z:
if you get an error 43 then it is an authentication error..
Let me know

@Noah, that is nonsense. A Trust is between domains, not machines.

@jskfan, \\DomainName\Username is no valid account. You probably mean DomainName\Username.
The popup tells "Access Denied", and that means the account is authenticated properly (account name and password are correct), but that account lags admin privileges, as stated by David. If you do not want to make that account a local admin, create a new share (because you cannot change privileges for automatic generated c$ etc. shares), and allow access for the user.

Try turn off the firewall on windows 7 computer and try connect again.


Thank you Guys for your inputs

Myadmin account is member of the local Administrators group in Windows7
form another computer that is member of the domain, I am typing
 \\Windows7\c$ , I get a pop screen to enter username and password. I type Windows7\Myadmin and password. However it does not connect me to \\Windows7\c$
Could be a smb 2.0 problem, can you check if the 7 system can map to the domain using user:domain\user password?

If no, could be smb 2.0 vs 3.0


From Windows7 to any Domain Member, there is no problem.... but not the other way around
can you map it to the IP?  \\10.2.3.\hiddenshare?


I used \\ipaddress\c$
I get a pop up to type in username and password, and typed \\\administrator  then password  [administrator and password for the remote computer], but still cannot access it
try using it in a command line
net use k: \\ipaddress\c$ /user:administrator password


I will get back to it later.
Thank you
