The specified domain either does not exist or could not be contacted

[RickL]

I am new to .NET (and directory services) and I need to fill a drop down list box with the users of my company. I am trying to use the code shown below, but I get this error message when the line of code with the "For" statement runs: "System.Runtime.InteropServices.COMException: The specified domain either does not exist or could not be contacted
Can anyone give me any ideas as how to resolve this? Any and all help would be greatly appreciated. Thanks
Dim DirSearch As New DirectorySearcher(userDSE
DirSearch.SearchScope = SearchScope.Subtre
DirSearch.PropertiesToLoad.Add("name"
DirSearch.PropertiesToLoad.Add("mail"
DirSearch.Filter = "(objectcategory=user)
For Each sr As SearchResult In DirSearch.FindAll <-- ERROR OCCURS HER
Dim li As New ListIte
li.Text = sr.Properties("Name")(0
li.Value = sr.Properties("Name")(0
ddlReporter.Items.Add(li

Rick,
If you receive an answer to this directly, please post back to the list. I
have been trying to resolve this very issue for some time now.

You didn't specify where this code is running and your code doesn't show
where userDSE comes from. Since that is the object that is going to
determine the security context and LDAP server, that is the important part.

Is this running under ASP.NET? If so, these articles will help you:
http://support.microsoft.com/default...b;en-us;329986

Also, I recommend you follow up in microsoft.public.adsi.general as that is
where the great majority of S.DS questions get fielded around here.

HTH,

Joe K.
