SSIS Script Task connecting to AD

I have written a SSIS 2005 script task that connects to Active Directory and reads user accountnames to store in database. I was able to successfully test this on my local system by executing dtexec.exe cmd. However, when I try the same on the server, the ldap query times out. The same ldap query as a console application just works fine.

I'm using .NET class: System.DirectoryServices.Protocols.LdapConnection and 开发者_高级运维SendRequest to retrieve user account names.

Could you let me know if I'm missing something?

Thanks!

Update: I'm actually getting "Ldap Server is unavailable" error. Still not sure, what might be causing this error.

Check the credentials that you are using in server to get the data from ADS. It should be a domain account I think. This will be different from what you used at development environment. Plus check if the DNS/WINS names you use is correctly getting resoled to IP address.
