Query LDAP directory (non-AD) using System.DirectoryServices

Query LDAP directory (non-AD) using System.DirectoryServices

(OP)
I am trying to query a public LDAP in my VB.NET application. The LDAP is not Active Directory. I found an example on the net, which makes no reference to AD. My test is based on that example. When I run this sample, an exception occurs, and I get the error "An operations error occurred.".
Suggestions are welcome.

CODE --> vb.net

Dim oRoot As DirectoryEntry = New DirectoryEntry("LDAP://123.12.12.1/ou=MYORG,ou=EXTERN,o=MO,c=CA") 'not the real IP
Dim oSearcher As DirectorySearcher = New DirectorySearcher(oRoot)
Dim oResults As SearchResultCollection

Try
    oSearcher.PropertiesToLoad.Add("cn")
    oResults = oSearcher.FindAll
    MsgBox(oResults.Count)
Catch e As Exception
    MsgBox("Error is [" & e.Message & "]")
End Try

Which line causes the error?

(OP)
The exception is raised by the line:
oResults = oSearcher.FindAll

If I take out the exception handler, my program just stalls at this line, and does not return.
