How can i search multiple computers outside domain   

Hi,

 Can any one help me please ,i am new to this active directory and LDAP
and WMI, my question is, how can i do a directory searching for
different computers, say,i am in "MYdomain" but i want to search
standalone  computers which are not part of any domain.

i am writing in c#  windows application, for eg:Say i am in one domain
called "mydomain", i can find all computers in that domain ,but if i
want to search  this domain computers  as well as stand alone computers
which are not part of any domain, then how do i search them.

below is the sample code


string rootDSE= <LDAP:\\DC="Mydomain",DC="Com"/>
System.DirectoryServices.DirectorySearcher DSESearcher=new
System.DirectoryServices.DirectorySearcher();
entry=new DirectoryEntry(rootDSE);
search = new DirectorySearcher(entry);
search.Filter="(&"+_ldapFilter+")";
search.SearchScope=SearchScope.Subtree;
results = search.FindAll();

I tried <LDAP:\\DC="worstation1",DC="MYDomain",DC="COM"/>

i get a error saying "a referral was returned from the server", can
anyone give a feed back what i am doing wrong.and can anyone show me
steps,its greatly appreciated.

thanks in advance

Re: How can i search multiple computers outside domain   

AD has no knowledge of computers that aren't in the forest. You have a couple of 
options

1. Scan the browse lists. Look at MSDN for browse list functions. You will 
probably have to pinvoke all of them.

2. Scan the network ip by ip looking for machines that respond and then sending 
various NET * calls at them. Again, you will probably be doing a lot of pinvoke.
