The first question is, “is your computer a member of the domain or workgroup?” If not, then you will be unable to see information about that domain or workgroup without additional effort. If you are joined, then contact your support team for assistance.
Note, browsing other domains or workgroups is not as simple as browsing the domain or workgroup to which your system is joined (Network Places will not list domains for which there is no truste. Accessing resources though is straightforward.
This now goes into cross domain authentication. Your domain administrators can either allow trusts from various domains which allow you access or you will need to manually authenticate to the domain or workgroup to see the information. In either case, you need an ID and password that has access to the domain or workgroup you wish to view.
Case 1: Contact the domain administrators and see if they will allow a trust between domains granting you access to the information (domain or workgroup).
Case 2: Contact the administrator of the other domain or workgroup for an ID with access and check on their policy for cross domain access. In this case you must authenticate to the domain or workgroup to gain access. In a domain scenario this is simply authenticating to the domain. Workgroups don’t allow for a simple method of obtaining this information when not a member. (It requires an in depth knowledge of NetBIOS and/or WINS).
To access resources in a secondary domain issue use NET USE to authenticate to the domain then you can access resources. The authentication is reset every time you logout, shutdown or reboot.
“NET USE \\DomainName /U:UserID@DomainName *”
“NET USE \\DomainShortName /U: DomainShortName\UserID *”
To map a specific share
“NET USE * \\DomainName\share /U:UserID@DomainName *” (any free drive letter)
“NET USE J: \\DomainName\share /U:UserID@DomainName *” (to a specific letter)
The asterisk after the ID prompts for password.
For workgroups, you must have an ID on the resource that you wish to access or that share must be open for anyone to access.
