我的asmx服务在我的本地机器的iis上运行正常，即win10。 但不适用于Windows Server 2008 r2

Question

I have a asmx web service which is just calls a method below KayitKontrol(). That method is using a com object. It works on my local machine but when it try it on server 2008 it stops at creating com object class Kernel.I have same settings on both iis. I couldn't figure out for a week. I profiled it with fiddler it just doesn't respond giving 504 response.

I didn't install application server. Is it something about it?

private void KayitKontrol()
        {
            using (SqlConnection conn = new SqlConnection("server=" + serverName + ";initial catalog=" +
                                                          dataBase + ";integrated security=false;uid=" +
                                                          sqlUser + ";password=" + sqlPass + ";"))
            {
                try
                {
                    foreach (var el in kasalist)
                        {
                            try

                                Kernel kernel = new Kernel();//stops right here which is com object.

Answer 1

Fiddler can't help you when the BL crashes... :) Anything in the windows event log? Where does your log statements (LogYaz) go, anything in there?

Answer 2

I found the problem. It was about the identity account in iis application pool settings. I set an administrator account there and it is working now. I am a newbie.
