Hi Bryan,
Welcome to ASPNET newsgroup.
>From your description, you have a certain asp.net web application which use
the System.DirectoryServices classes to make LDAP request to a remote
server. The application's ldap requery code works well on your development
machine, however you're encoutering "the server is not operational" error
when running a deployment server, yes?
AS for the LDAP query, are you accessing the ldap service through the SSL
port? If so , based on my experience, this should be a certificate related
issue. For SSL protected communication, when establishing the connection,
the clientside will validate the server certifiate in the local certificate
store, to find the Trusted root CA for that server certificate, if not
found , the connection establishing will fail. So if your ldap request is
really over SSL port, you can try checking your deployment server's
Computer Certificate Store's Trusted root CA to see whether you can find
the root CA for your ldap server's ssl server certificate. If you're not
quite sure on the root cert, you can checking the computer certificate
store on your development machine and compare them to see whether you can
find any clues.
Thanks,
Steven Cheng

| Hello,
| I have a asp.net app working with directory services on my Windows XP
| development machine. However when I moved the application over to our
| production server (Win 2000 Server) it no longer works.
|
| I use this code to try to connect to ldap:
| System.DirectoryServices.DirectoryEntry entry = new
|
System.DirectoryServices.DirectoryEntry(LDAP://corp.mydomain.com,user,pass);
|
| I tried using my user name and password, the domain admin user/pass but
keep
| on getting "the server is not operational" error. Now I know this is
| security related, but after a day and a half of trying to get it to work
and
| searching google i cannot find out how to make it work!
|
| I even tried using ldp.exe on the webserver, it worked fine. I was able
to
| connect right to the ldap no problem...
|
| Any and alll help is greatly appreciated!!!
|
| Thanks,
|
| Bryan
