How Can I Prevent My Co-Workers From Accessing My SQL Instance..
May 17, 2008
Hi all
In our office we have simple Network (LAN) and for some reason in each workgroup Computer in this network we have installed SQL-Server 2000.
So far everything was ok but recently i noticed that my co-workers can easily access my Sql Server Instance through their Enterprise manager installed on their computers and then they can open my tables,view...and manipulate other objects.
for better illustration i have created a Flash Movie from this process , please check the following Link :

How can i prevent others from doing so? Any help greatly Appreciated. Kind Regards.
Based on our database infrastructure, we need to secure our SQL databases. The security issue concerns on allowing a limited number of Domain Admin users to access the SQL databases. We tried certain ways, based on the documents in the Microsoft web site, but we couldn€™t reach to the point of preventing the Domain Admin users accessing the SQL databases.
Hi , I just put my files up on a web server. I can view my aspx pages..but when I try to login to the website I get the following; An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Can you help? I can understand that it cannot find the specified instance of sql server, however I don't remember ever configuring it look to at a specific sql server. When i created the site in web dev express edition and added the login controls and set the asp config tool to use internet security it created the database itself and so I didn't have to put a connection string in. I also cannot see a connection string in tthe web.config file. The aspnetdb.mdf file is there on the server. is this something i need to configure with the hosting company or do i set it in my webconfig file. Thanks

I'm having trouble accessing SQL2005 Standard Edition as a secondinstance of SQL Server where the first instance is SQL 2000 EnterpriseEdition. I installed SQL 2005 as a named instance "SQL2005". Theserver is running Windows 2000 SP4 ON A 32-Bit machine. When I look inServices I see the SQL Server (SQL2005), SQL Server Agent (SQL2005)services there. I went into SQL Server Configuration manager anddisabled the named pipes protocol and only have TCP/IP and by defaultShared Memory enabled to rule out that named pipes is causing theproblem. In SQL Server Configuration Manager I created an alias"computername$SQL2005" and was able to connect to database engine"computernameSQL2005" through SQL Server Management Studio WHILE ONTHAT BOX.But when trying to access the 2005 instance from another server(64-bit Windows 2003 SP1) I'm having trouble. On the 64-bit machine Idisabled the named pipes protocol for both "SQL Native ClientConfiguration (32-bit)" and "SQL Native Client Configuration". Under32-bit I created the alias "machinename$SQL2005" to point to the IPaddress of the 32-bit machine. In SQL Server Management Studio whentrying to connect to the database engine "machinename$SQL2005" itdefaults to the SQL 2000 instance. How do I access the SQL2005instance from a remote server?Any help would be appreciated.Mike
I'm having an issue accessing a newly installed SSRS instance. When I browse to the URL it states that "User 'BLAH' does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed.".
I've gone through various forum posts and followed steps such as running IE as an admin and disabling UAC but I'm unable to get past this unless I run IE as an admin.
I have attached some test data for you that has two temp tables "#worker" and "#worker_rate".
The issue is to find all workers who are sharing SAME SET of rate_codes.
I'm able to get the output as "workers sharing same rate_codes", but unfortunately I could not get the list of workers sharing same SET of rate_codes. Also definition of SAME SET is not defined.
I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.
I have to migrate all objects alogwith all constraints,SP,Triggers, indexes etc from Development instance to Production instance of a DB, all those things are created through wizard ie. Sql server 2000 Enterprise Manager. if i use DTS it only mirates data along with tables and views but constraints,SP,Triggers, indexes etc not yet copied.
can any body help me how can I solve this problem by copying all objects alogwith all constraints,SP,Triggers etc from Development instance to Production instance.
I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.
I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.
I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.
Should I be able to connect as serverinstances for a named clustered instance in 2012 ?
Hi, I have a task in hand to migrate (upgrade) from SQL2K named instance to SQL2K5 default instance. There are many intranet applications touching current SQL2K. I would like to perform this upgrade such that I don't have to touch any application code - meaning I don't have to change the connectionstring to point to new Default instance. How can I achieve this?
So, in otherwords, here is what I want to achieve:
Current Server: SQL2K: SERVER_AINSTANCE_A (named instance)
If I have both default, I could achive this by setting up DNS alias after migration done so that any call for SERVER_A would point to SERVER_B. But in my case, I don't have SERVER_A, I have named instance. Is there any solution?
I want to move one database from the source SQL Server 2000 instance to a new SQL 2000 instance in another machine. I have five user databases in this source SQL instance. How should be my approach to move this single database out of this ? My understanding is restoring this database in the new instance, copying all logins to the new instance and then copying the jobs, DTS packages, alerts, operators only specific to this database will do it. Please let me know if this is exactly what I should do ..

I am trying to set up a Named Instance of SQL 2000 on the same machine that has a default instance of SQL 7.0. The setup always completes and I am able to register the Named Instance of the SQL Server with which it was installed on. However, when I try to connect the users to the database, with both windows and SQL authentication, I receive a SQL server not found error. I have tried an alias setup as well as physically specifying the port number in settup up an ODBC connection. Has anyone ran into similar problems? Also, has anyone been able to successfully complete the process as mentioned above?
I have a server with sql server 2005 installed as the default instance -- I have a piece of software that needs SQL2000 to be the default instance. Is there a way other than install new sql2005 named instance and move databases to rename my SQL2005 instance from <machinename> to <machinename>sql05 for example?
i have installed SQL client instance on my Desktop "Machine-A", and i used to connect to SQLServer2000 running on another "Machine-B" by using valid username and password.
i created a DTS package and i used to run it. im very confused how the communication happens between the two machines and which process run where and which initiates which and which machine allocates waht resources. im really interested to know all these things. if any one know plz help me out.
I work for a mid size company with the usual collection of enterprise applications. We are trying to consolidate our SQL environment consisting of around 100 databases none of which are over 100GB with the average database size around 5GB. Recently a large server was purchased as the "Big Daddy" SQL box. Obviously not all the databases will be moved to this one box but within reason a number can.
My question: What is the best way to configure the box?
1 OS & 1 Default Instance - How do we isolate loops memory leaks etc... 1 OS & Multiple instances, ie:Dedicated instance for each application. - How do you allocate CPU & memory, allow for optimum performance without putting others at risk from a rouge process? Virtualized OS for each application with a default instance - Too much overhead impacts performance?
Future plans include offsite replication, perhaps mirroring with failover.
I'd appreciate anyone else's thoughts ideas? How have you tackled this problem in your environment?
I installed SQL Server 2005 recently on a cluster. I didn't go for the default instance and instead I named the instance option. Now I would like to migrate everything from the named instance to the default instance, which I haven't yet installed.
Is this an easy process? What about the logins and the maintenance plans and jobs? Is there anything else I need to be aware of?
I've never had to do this, but when I downloaded the Web Workflow Approvals Starter Kit, it requested that I install the database into a User Instance of .SQLEXPRESS.
Now the problem is, I've installed it onto a default instance, so I was wondering whether you can create a named instance on top of a default instance... and if so, how would you do that?
Got windows Vista Business edition, installed Visual Web Developer Express, SQL Server 2005 Express SP2, SQL Server Management Studio SP1 in that order. I was developing in VWD express without problems using WinXP but now on Vista Business, the local connection to SQL server appears to be a problem. I know there's nothing wrong with my web.config or anything like that as it was working perfectly prior to running under Vista. If i specify the database on the live website, it works fine. If I specify the test database in app_data folder, I get the following exception:-

I am taking a guess it's somerthing to do with access issues, but can't find anything out on searching the forums etc.. I am setup as an administrator, running VWD as an administrator and for the record, SQL Server Management Studio express works fine. Another small issue, when I run the application from VWD, I always have to minimise the application and restore it as the graphics get corrupt. Please help!! I cannot debug when running of the live website.
I am building my first ASP.Net app from scratch and while working on the DAL I came across the problem of SQL Injection. I searched on the web and read different articles but I am still unsure about the answer. My question is should I add
Add in Parameters to my C# code to avoid SQL Injection. What is the best practice. I am unclear if the stored procedure already helps me avoid SQl Injection or if I need the add in parameters in the C# methods to make it work. I need some help. Thanks, Newbie
My C# update method in the DAL (still working on the code)
private static bool Update(AvatarImageInfo avatarImage) { //Invoke a SQL command and return true if the update was successful. db.ExecuteNonQuery("syl_AvatarImageUpdate", avatarImage.AvatarImageID, avatarImage.DateAdded, avatarImage.ImageName, avatarImage.ImagePath, avatarImage.IsApproved);
return true; }
I am using stored procedures to access the data in the database.
My update stored proc
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO

Have a job that calls a DTS package, DTS is an Export & Import wizard to copy tables. Someone deleted a table from source and my job failed last night. Inputs appreaciated.
I'm going thru my application log, and just seeing what errors are popping up. I have a relatively intense search feature, thats causing alot of deadlocks.
Exception type: SqlException Exception message: Transaction (Process ID 105) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
In general, what's the best way to resolve this ?
Should I see if I can apply "WITH (NOLOCK)" to my data ?
I want to try and protect myself from my own stupidity. I have a number of sql databases, but one is LIVE. It is easy to drop tables but I want to set something (e.g. a password) which will help prevent me from dropping tables on the live database.
Hi,I'm using SQL Server 2000 MSDE on a laptop running Windows XP.I have a couple of SP's that that quite some time to compile. So I waswondering: is there any way to have the database *not* recompile them everytime after a reboot?BOL says: "As a database is changed by such actions as adding indexes orchanging data in indexed columns, the original query plans used to accessits tables should be optimized again by recompiling them. This optimizationhappens automatically the first time a stored procedure is run afterMicrosoft® SQL ServerT 2000 is restarted."Now the SQL Server is restarted a lot, because laptops don't have endlessbatteries <g>Cheers,Bas
The box I am trying to connect to is running two instances of SQL Server. There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'. I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" /> However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried: <add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" /> but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used: <add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" /> but this doesn't work either.
Am I mssing something here? Any help much appreciated Thanks...

If you were asked to install SQL 2005 on a machine, would u install a default instance or a named one? And why would u choose one over the other?? Also, r there any issues with using a default instance?
