Issue with LPAD and gives error The server is not operational

Nov 22, 2012 05:29 PM|LINK

Hi,

I am working with LDAP but it keeps giving me error "The server is not operational". I thought may be I am using wrong credential. Therefore I tried with Google and it did not help me.

Enclosed please find my code:-

using (DirectoryEntry dir2 = new DirectoryEntry("LDAP://www.google.com:389/DC=www,DC=google,DC=com", null, null, AuthenticationTypes.Encryption))
            {
                dir2.RefreshCache();

                DirectorySearcher adSearch = new DirectorySearcher(dir2);
                adSearch.Filter = "(&(objectClass=*)(msExchRecipientDisplayType=7))";
                SearchResultCollection adResult = adSearch.FindAll();

It gives me error on : dir2.RefreshCache();

I am not sure, what I am doing wrong. I have tried with different LDAP values like :-

using (DirectoryEntry dir2 = new DirectoryEntry("LDAP://ldap.google.com/DC=www,DC=google,DC=com", null, null, AuthenticationTypes.Encryption))

using (DirectoryEntry dir2 = new DirectoryEntry("LDAP:///DC=www,DC=google,DC=com", null, null, AuthenticationTypes.Encryption))

using (DirectoryEntry dir2 = new DirectoryEntry("LDAP://DC=www,DC=google,DC=com", null, null, AuthenticationTypes.Encryption))

But nothing really helped me.

Enclosed please find the stack trace:

COMException (0x8007203a): The server is not operational.

I have tried to follow the enclosed link as well but no help:

I am working on Windows Server 2003 and trying to connect Exchange 2007.

Any help or suggestion would be greatly appreciated.

Thanks in advance !!
