COMException 0x80072020 with LDAP Query

[Tatopitta]

Hi all,
I've read many times some threads with this problem but no answer is
simple and good enough. Here's my situation:I've developed a web
application with query LDAP which from System.Environment.UserName gets
Name,Department, and so on. It works fine if I access the site with
http://localhost/Site, but if I use
http://Server/Site it gives me the following error:
[COMException (0x80072020): An operations error occurred.
]
System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail)
+610
System.DirectoryServices.DirectoryEntry.Bind() +36
System.DirectoryServices.DirectoryEntry.get_AdsObject() +31
System.DirectoryServices.DirectorySearcher.FindAll(Boolean
findMoreThanOne) +73
System.DirectoryServices.DirectorySearcher.FindOne() +42
MasterPage.GetID() in
c:\inetpub\wwwroot\trackingactivity\MasterPage.master.vb:19
MasterPage.Page_Load(Object sender, EventArgs e) in
c:\inetpub\wwwroot\trackingactivity\MasterPage.master.vb:7
System.Web.UI.Control.OnLoad(EventArgs e) +99
System.Web.UI.Control.LoadRecursive() +47
System.Web.UI.Control.LoadRecursive() +131
System.Web.UI.Page.ProcessRequestMain(Boolean
includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
+1061

and the source of the problem is the function:
Result = mySearcher.FindOne()
So, the server is in my domain, I use VS2005, iis settings are:
Enable anonymous access --> NO!!!
Enable Integrated Windows, Digest, Basic Authentication

Please, what can we do to make it work?))

Thank you.
