hi every one.

I have two major problem with my windows server 2008 that I couldn't find any solution for them.

MY first problem is:

I've installed SQL server 2008 and ran an ASP.net Application (I have wrote the application) on IIS 6.

For debugging the program also I have installed Visual studio 2010.

While running the application on visual studio I have no problem to access my database on my SQL server but on the IIS my website can not access the data base.

I have checked my Connection string and every thing which link my site to the data base server. Nothing is wrong with them. I thing the problem is with the firewall but I can't fix it !!

 

and my second problem is:

I've install MDaemon Mail server v9.5.2 on my windows server. while i'm accessing MDaemon World client on 192.168.0.35:3000 from my machine every thing is OK but in my local network (ofcourse it's obvious with no internet connectivity) i can't access the IP from another machine. also I think the problem is with my firewall but again I can't solve it.

I need you help a lot.

waiting for your solutions....

hi there,

 

Just to be sure your problem is the firewall, temporarly disable it and check both applications. If this resolve your problem, re-enable your FW and post again so we can investigate on your problem. If this doesn't help you in any way, post again for the same reason as before :)

 

cheers

Thank you very very much for your answer

It worked!!

but still I have problem with my sql server. My web site can not access my data base.

And also I have another question:

What if I turn my fire wall ON? How should I configure my firewall not to have problem with my MDaemon mail server and SQL server?

You have to open the rights ports on your FW:

 

Because of the many different scenario you can have, I suggest you to read this article from MS, which explains not only HOW to configure (allow) a program with Win FW, but also the ports used by SQL.

 

http://technet.microsoft.com/en-us/library/cc646023.aspx

 

Regarding your other problem, I suggest you to try to add a simple ODBC connection and see if you can retrieve any info.

 

Can you post the string you use to connect from your app?

 

thanks.

Thanks for the given topic

I follow the solutions. I added two rule in my firewall. One for opening port 1433 and another for opening access to SQL Server when using dynamic ports.

But unfortunately problems are not gone.

My app can not access the data base.

this is the string which I used in my app to retrieve data :

 

Data Source=WIN-WKMIE6IIDYJ\SQLEXPRESSInitial Catalog=PazhooheshIntegrated Security=True

 

My database does not have any username and password !!

 

And my second problem is still there. when I turn my firewall off MDaemon can be accessible on port 3000 (my IP:3000) from another machine but when I turn it on, same problem.

 

I added four rules for both peograms (sql server and MDaemon) !! Two in Inbound rules (port and program ) and two in Outbound rules but my problems are not gone.

 

before any thing, thank a lot for your helps!!

I'm not really a good programmer... but I can remember that when I need to connect to a SQL server I prefer to use integrated auth. I used this whitepaper:

 

http://www.asp.net/learn/whitepapers/aspnet-and-iis6

 

take a look at the end "Supporting integrated authentication with SQL Server"

 

 

Regarding your firewall, you surely have done something wrong with rules.

 

Let's start from Mdaemon. Yours rules may be correct, but you have to allow EXEs too.

 

From the KB of Mdaemon, you should permit these EXEs:

 

MDaemon.exe 
WorldClient.exe 
WebAdmin.exe 
MDSpamD.exe 
AVUpdate.exe

 

The same thing must be made for SQL server's executable.

Thank you for your answer.

Regarding MDaemon problem, you were right. I should add above EXEs file to my firewall allowed program list.

It's working well.

but regarding SQL I do the same but nothing changed!!

The problem still exist !!

I don't know where is the problem!!

I opened the ports 1433,

I allowed almost all of sql EXEs files to be run throw my firewall

I added rules just by the way that was said in Microsoft's official web site.

My string Connections are right.

My app. is working in Visual studio 2010 very good but in IIS it is not.

I'm so confused!!

Is there an other way ?

Waiting for your answers...

My string Connections are right.

 

I don't think so.

 

When you disabled FW, you haven't resolved your problem.

 

have you followed the guide found in the link above?

 

What I mean is that MAYBE the problem is the "blank" authentication...

What I mean is that MAYBE the problem is the "blank" authentication...

 

!!

well you mean the problem is with my connection strings?

 

If it is, so why I have no problem in visual studio?

Let's assume that, that is the problem, how should I change my strings into the correct form?

Let me say something honestly, I didn't catch your meaning by: " The problem is the blank authentication."

Well, I never tried to authenticate without username / password or at least windows auth.

 

I just think you may have created a connection in visual studio (from the wizard) and you have the connection from there. Once you launch the program without visual studio, it doesn't know how to authenticate.

 

Can you post the error message?

Well I don't know you may be right

The error I get is very simple:

Object removed here!!

 

which "here" is linked into the first page of my app. (Default.aspx) !!

Mhhh this make me think that your string is correct...

 

Do you installed the last framework version? It should be 4.

 

Also, the error you have should be OBJECT MOVED HERE and not object REmoved here. Is it correct?

Well, this app is on framework 3.5 and this framework is installed on my server but I don't know is it necessary to install framework 4 or not but I'll install it.

Regarding my error i should say, yes, you are right :D It is OBJECT MOVED HERE which "HERE" is linked to my first page "Default.aspx".

I still have problem and I couldn't find any solution.

Waiting for you answer...

Mhhh no, you don't have to install Framework 4, the problem was only with 1.

 

So take a look at your code. First of all make a try, use Firefox or Chrome and notice if you have the same problem.

 

Then, in your code, make sure you have these lines:

 

(provided by a programmer to me):

 

'Before the redirect code, place this:
Response.BufferOutput = true

 

Still the programmer says:

if you are redirecting a page, remember that once your HTML code has been sent to client, you CANNOT redirect a page, unless you want to use JavaScript.

 

 

Let me know.

I try " Response.BufferOutput = true " but result was the same!! :((

 

This is the Code I use in my page:

string NationalCode
ADO AD = new ADO()
bool checkRow = true
String url = ""
string connection = "data source=LEGEND\\LEGEND initial catalog=Pazhoohesh integrated security=SSPI"
SqlConnection Con = new SqlConnection(connection)
SqlCommand Com = new SqlCommand("", Con)
SqlDataReader DR
Com.CommandText = "select [LogIn].LNationalCode,Person.ID,Person.ImgDirectory,[LogIn].LogintType,[LogIn].OK from [LogIn],Person where Person.NationalCode=[LogIn].LNationalCode " +
"and [LogIn].UserName='" + this.TextBox1.Text.ToString() +
"' and Password='" + this.TextBox2.Text.ToString() +
"' and LogIn.LogintType='" + this.DropDownList1.SelectedItem.Text + "'"
try
{
Con.Open()
DR = Com.ExecuteReader()
DR.Read()
if (!DR.HasRows)
{
checkRow = false

}
else
{
string image_link = DR["ImgDirectory"].ToString()
String ID_hold = DR["ID"].ToString()

switch (DR["LogintType"].ToString())
{
case "?????":
if (DR["OK"].ToString() != "True")
{
url = "NotAllowed.aspx"
break
}
url = "ControlPanel/Prof.aspx?"
NationalCode = AD.encrypt_Nationalcode(DR["LNationalCode"].ToString())
url += "NC=" + NationalCode + "&Img=" + AD.encrypt_Img(image_link) + "&LE=" + AD.encrypt_Nationalcode(ID_hold)
break
case "???? ????":
url = "SiteManager/SMHomePage.aspx?"
NationalCode = AD.encrypt_Nationalcode(DR["LNationalCode"].ToString())
url += "NC=" + NationalCode + "&Img=" + AD.encrypt_Img(image_link) + "&LE=" + AD.encrypt_Nationalcode(ID_hold)+"&SW=0"
break
default:
break
}

}

}
catch (Exception t)
{
}
finally
{
Con.Close()
}
if (!checkRow)
{

Response.Redirect("NotFound.aspx")
}
else
{

Response.Redirect(url)
}

 

 

Is there any thing wrong with my codes?!!

From my poor knowledge of web programming, your code is ok...

 

the only thing I can suggest you is to ask on a dedicated programmers forum, this is not a "server" problem. It is just a suggestion, I can't help you anymore with this, sorry.

Well Thank you very much

You helped me a lot. I learned so many things here

I'll check my problem in programming forum )

Hi every body.

regarding problem I had (the SQL server one - I had two problems if you remember), I should say that I could fix it

The solution was:

1) My log in SQL account (sa) was disable which should be enabled. To enable that I did the following:

Under my server name in SQL server management studio->security -> logins-> sa-> double click on it -> click on Status from the right pan -> check the enable radio button

2) SQL login mode must be a mixed form of windows authentication and SQL server authentication. To change that I did the following:

in SQL server management studio right click the server at the root of tree menu in left pan -> select properties -> security tab from left pan -> exchange server authentication from "Windows authentication mode" to "SQL server and windows authentication mode"

3) In the connection string I added the "sa" as Username and it's password as my login account to sql server

you can do the same for another account which you want to be confirmed instead of "sa" !!

here is my e-mail address for more help if you have the same problem and I could help you
