query AD - Domain does not exist error

[j-in-uk]

Dim subtree As New DirectoryEntry(ADRootQueryString, "domain\loginame",
"Password1", AuthenticationTypes.Secure)
If validCharacters.Match(name).Success Then
rootPath = String.Format(ADDefaultContextQueryString, _
subtree.Properties("defaultNamingContext").Value.T oString)
filter = String.Format(ADPathQueryString, name)

Dim search As New DirectorySearcher
'Error at the this line
search.SearchRoot.Path = rootPath
summaryResults = Find(rootPath, filter)
end if

I am trying to query the AD on a localhost project and have valid login
details for that AD, it seems as thought it does not like my
credentials, I get the error : "The specified domain either does not
exist or could not be contacted" on line
search.SearchRoot.Path = rootPath
Any suggestions?

It makes no sense to post incomplete (VB)code samples to a CSharp NG, all we
can do is guess how the missing parts look like. Now, my best guess is that
you are trying to bind to the "RootDSE", while you are logged on locally.
For this to work you need to logon into a domain for which you try to bind
to it's root.
