Securing The MS SQL Server 2005 Database On Client Side
Apr 27, 2006
Hello!
I developed database driven .NET application and I need to deploy it. I faced a problem, which is "how to protect my database against direct access". I use MS SQL Server 2005 Express Edition as a DBMS and appropriate database.
I want to make possible to manipulate with data in my database only through my client application.
1. How do I define SA password and instance name in silent mode of MS SQL 2005 EE installation with Mixed type of Authentication?
1.1. Can I change SA password after the installation?
2. If my database be attached to my new instance... Is it possible to copy my database, attach it to another instance and get a direct access to its objects?
Is there solution that make impossible to connect to my database on third-partie's side Idirectly, without using the client application?
I appriciate for a help.

Hi,
In Analysis Services there is an option to enforce a role either on the client side or the server side.
Can someone kindly guide what's the recommended approach and what's really the difference between the two options.
Thanks.

I will soon be embarking on an upgrade of a transaction replicated database (Push) from 2005 to 2012 SP2.The publisher, distributor and subscriber are 3 separate machines.There databases will be detached, MDF and LDF will be copied across. Once attached, replication will be set up from scratch.
The name of the new servers are NOT the same as the existing ones.Should I completely remove transaction replication user the wizard and unticking the DB from being a database for transactional replication or just stop the log reader agent?How can I make sure the last of the transactions have gone across before I detach?Should I detach the subscriber first or the publication? Does it even matter?
Is there a better way of moving across the databases? I for one would have preferred to backup (.bak) then restore on the other side. I'd love to hear opinions on this as well.

I have SQL Express 2005 with Advanced Services on a development box that I also want to have installed side-by-side with SQL Server 2005 Standard Edition so I can develop apps using either edition based on the features I need (or don't need). From what I understand from sifting through other posts is that side-by-side installs of these two editions is supported and I should setup a named instance for each edition (SQLEXPRESS for the express edition and MSSQLSERVER for the standard edition). Is this setup accurate or is there another/better way?
Also, does anybody know if side-by-side installations of Reporting Services is also supported? If I install SQL Server 2005 Standard Edition with Reporting Services, will there be two different report servers running in IIS? Since there are different features in Reporting Services between the two editions, I'm not sure how side-by-side installations will effect one another.
Thanks in advance for any help,
Tony

We have some developers who manage SQL2000 servers from their WinXP workstations using Enterprise Manager. We have now rolled out our first SQL Server 2005.
Can we install the SQL2005 Management Studio side-by-side with Enterprise Manager on these WinXP workstations?
If not, what are most people doing in these cases?
Thanks!

We have just updated our sql 2005 server with sql SP 1. Should we apply this service pack to the client boxes that access this server or is that unnecessary?
TIA,

Hi All,
My apologies if this question seems abit basic, but I'm a DBA by trade and programming .Net isn't my strong point ;)
I've enabled database mirroring on 3 SQL 2005 servers, a principal, a mirror and a witness.
Principal - SQL 2005 Enterprise Edition, SP1
Mirror - SQL 2005 Enterprise Edition, SP1
Witness - SQL 2005 Express, SP1
I've written some test code to test the mirroring but as soon as the connection is pulled from the principal, the client re-direct doesn't work and the program bombs. I'd be grateful fi someone could have a look at my code below and tell me if there's any schoolboy errors??
(NB, the user running the code is a sys admin on all 3 servers)
Thanks in advance.
Imports System.Data.SqlClient
Public Class Form1
Dim DCTADS As New SqlClient.SqlConnection
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
DCTADS.ConnectionString = "Network=dbmssocn; Server=STUD; Failover Partner=DBDRTEST; Database=mirrortest; Integrated Security=True"
DCTADS.Open()
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim cmd As New SqlClient.SqlCommand
cmd.CommandText = "Select fulldesc from unclproduct where internal = '20000110'"
cmd.Connection = DCTADS
Dim dr As SqlClient.SqlDataReader
dr = cmd.ExecuteReader
MsgBox(DCTADS.DataSource.ToString)
If dr.Read Then
MsgBox(dr("fulldesc").ToString)
End If
dr.Close()
End Sub

I have a Windows 2003 Server running IIS 6.0 and SQL Server 2005. I have just (Today) deployed the first ASP.NET application (developed in Visual Studio 2003 and, as such, dependent on .NET Framework 1.1) on this server and am getting HTTP Error 403 (You are not authorized to view this page). This ASP.NET application runs fine on another server that is configured with the OS=Windows Server 2003, IIS=6.0 but without SQL Server 2005 and without the .NET Framework version 2.0. I found in the IIS Application configuration (on the troublesome site) that my app (in the Default Web Site folder) was pointing to the version 2.0 aspnet_isapi.dll. All efforts to use aspnet_regiis to "re-align" my app with version 1.1 have been fruitless to eliminate the HTTP Error 403. I granted the NETWORK SERVICE account privledges to the wwwroot folder. At this point, I don't know if I have a Framework error or a privileges problem.
Please help.
Thanks,
Rob

I am trying to migrate from my current system, where I do merge replication from Windows Mobile devices running SQL Server CE 2.0 to a central database running SQL Server 2000 sp3a. I want eventually to move to a system running SQL Server 2005 CE replicating to a SQL Server 2005 back-end. But the transition will need to be gradual, and I may have to support both systems for a while until I can convert all clients from the old system to the new. I also need to do thorough testing.
So ... I'm trying to set up a test environment giving me the maximum possible flexibility to do my testing. Ideally, I'd like to set up SQL Server 2000 and SQL Server 2005 on a side-by-side basis, in a manner that would potentially allow mobile devices running both SQL Server CE 2.0 and SQL Server 2005 CE to sync with either back-end server.
Can someone provide me with guidance as what is possible to set up here? I know that SQL Server 2000 and 2005 can be installed side-by-side on the same server. It also appears that you can set up SQL Server 2000 so that EITHER SQL Server CE 2.0 OR SQL Server 2005 CE can sync with SQL Server 2000 (see www.microsoft.com/sql/editions/sqlmobile/connectivity-tools.mspx), but I don't know if it's possible for BOTH SQL Server CE 2.0 AND SQL Server 2005 CE to sync to the same SQL Server 2000. As for SQL Server 2005 ... it appears to be possible to set up SQL Server 2005 so that BOTH SQL Server CE 2.0 devices AND SQL Server 2005 CE devices can sync to the same SQL Server 2005 (see web page cited above). However, I don't know if it's possible to set up a SQL Server 2005 server installation in this manner while at the same time having a side-by-side SQL Server 2000 installation supporting any level of mobile merge replication.
HELP!!!!

I don't know about the evel version since I have not install yet. Any idea ?

having installed 2005 first and installed 2000 with both types of reports going to one 2005 home. i would like to have separate homes
with reports going their respective homes. Do i have to first unstall
2005 and do a new installation with a different report and server than
2000. I would like to avoid this and just fine tune 2000 with the rsconfig.exe. Help me out please.

I have one standby server that I use for multiple production DB SQL Server 2000 servers. We are upgrading one of the production SQL Servers to 2005. I will install 2005 on my standby and run 2000 and 2005 side by side.
Is this okay? Are there any caveats specific to running 2000 and 2005 on the same standby server?
Thanks!

I plan to upgrade my server to SQL 2005. It is a rather old machine, but still ok with the recommended hardware requirements.
It runs Windows 2000 (SBS) server, which is also a PDC, DHCP, DNS, Exchange server (I stop here but the list is long), with SQL Server 2000 Standard Edition (one single named instance). Everything localized (Italian).
I upgraded the database in a development machine and it works perfectly.
I installed SQL 2005 Standard Edition (English locale) on the server (default instance, MSSQLSERVER), and I have run in a lot of troubles.
The problem seems to reside in the TCPIP network protocols. If I enable TCPIP in the 2005 Server Configuration Manager, the new instance (MSSQLSERVER) does not start (this prevented me from upgrading to SP1 until I realized the cause, disabled TCPIP protocol and was finally able to update).
If I understand correctly, the problem is that both instances, the old 2000 one and the new one, try to listen to 1433 port. I changed manually the port to 1434 in the Server Configuration Manager. The result is that both SQL servers work, but none is working ok. I have several applications accessing the server. The asp application works. The .NET aspx one doesn't.
A tipical error I get is:

Background information:
I have been researching BOL, this forum, and the SQL Server help: Working with Multiple versions installation documents since yesterday. We have an AMD x64 multi-processor IBM server running SQL Server 2000 under MS Windows 2003 Enterprise SP1. SQL Server is installed in the "c:program files (x86)" folder. I wanted to verify that we were indeed running the 32-bit version of SQL Server 2000 so I also ran the @@version command from isql and it returns:
Microsoft SQL Server 2000 - 8.00.2162 (Intel X86)
Goal:
We need to install SQL Server 2005 Enterprise Edition 64-bit in a side by side installation. We will be migrating the SQL 2000 x32 stuff over to SQL 2005 x64 at a later date. My research shows I should be able to do this without any issues.
Have I missed anything or does it look like I am ready to move forward?

I am planning on installing SQL Server 2005 first and then install SQL Server 2000 as a separate instance on the same server. Has anyone had any experience with this setup? When I ran the SQL 2000 set up it didn't force me to create a new instance but I still did. I also installed the files on different directories c:program files just in case. If you have any experience of ideas about this configuration, please let us know. Thanks.

Hello,
I developed a small desktop system using SQL Server 2005 Express as the data backend. The machine that hosts SQL Server 2005 Express, as well as all the workstations that interact with it, belong to the same private LAN segment. All of them have non-public IP addresses from class 192.168.0... which means they're not directly visible from the outside world, despite having internet access through a router that does NAT. As we all know this is the typical scenario for sharing internet access in a small LAN.
Now, my concern is with the security of the host running SQL Server 2005 Express. In particular, what measures do I have to implement to minimize the risk that may come from the public internet ? It's naive to think that because the potential attack surface is NATted behind a router, security is guaranteed and data theft or DoS attacks won't simply happen.
What are the guidelines for securing SQL Server 2005 Express in a scenario like this ?
(Side note: SQL Server 2005 Express is running on Windows XP Pro)
Thanks.
Fernando

I having a difficult time here trying to figure out what to do here.I need a way to scroll through a recordset and display the resultswith both forward and backward movement on a web page(PHP usingADO/COM)..I know that if I use a client side cursor all the records get shovedto the client everytime that stored procedure is executed..if thisdatabase grows big wont that be an issue?..I know that I can set up a server side cursor that will only send therecord I need to the front end but..Ive been reading around and a lot of people have been saying never touse a server side cursor because of peformance issues.So i guess im weighing network performance needs with the client sidecursor vs server performance with the server side cursor..I am reallyconfused..which one should I use?-Jim

I want to know how I can protect my SQL Server database. SQL Server 2000 does not have Database Encryption feature and using only Authentication is not a fool-proof solution, as far as stand-alone desktop application is concerned.
Does password protection of SQL Server 2000 database really works when you have all types of cracking tools widely available on the net?

I have a DLL that I have written in VB to automate certain functions in Mapinfo. I can use the DLL from Access or a VB project fine but I have problems in SQL Server 6.5. I can create an instance of the DLL ok using sp_OACreate, but when I call the function to create a Mapinfo Object in the DLL I get a VB error back 'Permission Denied' and my object is not created. Even so, the instance of Mapinfo is started (I can view it in my task manager)which I subsequently cannot close because according to the DLL it was never created!! I think this must be a SQL Server related problem since it works fine in VB/Access.
Any Ideas ??
Scott.

Hello.
Not an SQL admin. We have an SQL 2005 server that has about 5 DB's on it. One database is maintained primarily by a third party. Often when they need to do upgrades they login remotely to the desktop of our SQL server. Is there a way to apply permissions to specific databases like you would for NTFS? That way they can only backup their database and not do anything to any other databases? Thanks.
