Code works in Windows app. but not in ASP.Net

I get this error in the webbrowser:
"The specified domain either does not exist or could not be contacted"

The code for the procedure is:
Sub ListUsers(ByVal DOMAIN As String, ByVal OU As String)
Dim srch As System.DirectoryServices.DirectorySearcher
Dim result As System.DirectoryServices.SearchResult
Dim de, dir As System.DirectoryServices.DirectoryEntry

de = New System.DirectoryServices.DirectoryEntry("LDAP://"; & DOMAIN
& "/" & OU)
srch = New System.DirectoryServices.DirectorySearcher(de)
srch.Filter = "(&(objectClass=user)(objectCategory=person))"

For Each result In srch.FindAll()
dir = result.GetDirectoryEntry
txtTest.Text = txtTest.Text &
dir.Properties("distinguishedName").Value & vbCrLf
Next
End Sub

I use the exact same code and the exact same call to the procedure in a test
Windows-app with no problems. So I am guessing some rights problem. Which
rights are needed and which user needs them?

Thanks.
