Hello,
Does anyone know how to prevent a certain machine from accessing SQL server? We have users who use a generic username and password (i.e. one login for 15 users) and I need to prevent a certain machine (in a high risk location) from hitting my databases. Any ideas
Thanks for your time and help

I'm using MSSQL7, NT authentication and application roles so only my application can access the data. Also, other applications (like Excel) can not access the data and read it. So far, so good...
Yet, I noticed that if I try to access the SQL Server from another SQL Server on the network, it is allowed to see the list of tables, SP, etc. It is not allowed to open the table, but the Import/Export wizard is working and will allow retrieving data from the secured tables.
If I change to MSSQL authentication, any user will be able to access the data from my application and I don't want that either.
Unless I'm missing something, this is a big problem, especially today where any VPN connection with valid user name and password can actually log in to the domain and therefore connect to the database via SQL Server.
By the way, the server still must allow access to users via applications so logins must exist. I just don't want other SQL servers on the network to be able to connect to and import/export, view table and SP, etc.
Any ideas?

Is there a way to use trusted connections in ASP.NET and WinForm applications yet prevent users from accessing databases directly (outside of applications) ? I know the use of trusted connections are recommended for several reasons however I have a lot of applications that I need to prevent users from accessing databases directly outside of the applications themselves.

Hi €“
We have built a .NET on SQL Server application with extensive business functionality and security. It uses SQL integrated security to control logon and access to the database objects. There is business logic built into the .NET code, so I don€™t want any chance that users access the tables directly through a tool such as Management Studio - many users need update, delete, insert on tables in order to use the applications functions. With integrated security they can logon through SQL Management Studio and change data in the tables directly.
How are people who are using integrated security for their business applications preventing logons through unauthorized tools or applications?

We plan on moving our sql 2000 db's to a sql server 2005 box this week.
What's the best way to point RS to the new database machine?
I'm not extremely familiar with Reporting Services and would like to know are there any "gotchas" in doing this?

Hello all. I am a baby new database administrator who hasnt finished all the courses yet. I have my Administration exam but not the Implementation yet. I got hired anyways! woo hoo.. Anyways, my question is this. I have a SQL Server 7.0 machine and its databases. I have been asked to move it all over to a new, skookum fast machine with access to 3.6 Terabytes of storage. I have been researching the best way to do this but am not sure. First there is detaching and reattaching the databases. I dont like this one cuz when I have done some practice ones it completely erases the databases of the original machine. The other way I was considering was using DTS. This is easy to use with the DTS wizard but the transaction logs of the databases are not transferred. What would be your advice on this move?? I need to make a this a reasonably seemless move. Help!!

I have package on a single server. This packages extracts Data from System A and loads System B, database C. What I'd like to do is use configurations to have this one package loads System B, database C and D.
When a I create two configurations (one pointing at database C and one pointing at database D) and run the package only the last configuration pointing at database D gets loaded.
Anyone know how to get around this and use configurations to load both database C and D?
Thanks,

I use SQL 7.0 server to build large scaled Web application.
I want to know that reasonable number of database in single machine. I know
single machine can get a 32,767 database in SQL 7.0.
We think database deploying method as following two cases.
Case 1)
We will provide multiple web application services and each service will be put into each database. Some table in a database will get about 1,000,000 records. 1,000,000 users will access each database. The number of services will be 100.
Case 2)
Or, we group 4~10 services and these group put into one database and another group of services put into another database.
What is the best database deplying method that reliable to performance and maintenance ?
machine A and B in the same network.
A has dbs A1, A2,A3...
B has dbs B1 B2 B3....
I conect to B first using sql query analyzer. how I can access A1 in A?
Thanks.

Dear All,I am developing a network application in asp.net. The database is in local machine having sql 2005. But the user database is already existent. So I am accessing that database which is sql2000. does it give any problem while connecting from sql2005 machine to sql2000. If yes it is giving me error as follows: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: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)connection string is :"Data Source=192.168.1.16,1433;Network Library=DBMSSOCN;Initial Catalog=mycatalog;User ID=myuserid;Password=mypwd;" Please correct me if I am wrong. Thanks and Regards.Fazal
View 2 Replies View RelatedAccording to my technical support for web hosting, for database format they only use "MS SQL" operating on a windows system, usualy clients create they're sites on their local machines using "MS SQL".
I'm just wondering.....
Is 'MS SQL' free? where can I get it?
I also have the option of creating the site round an access databse but I'm worried about the security issues,
do you think it would be wise to use access?
Is it easy to convert a site written in ASP.NET&ACCESS into a site using ASP.NET&"ms sql"?
because then I could code a site in the former on my machine and then change the code to link to an sql server.
I was just trying out Microsoft SQL Server 2000. I created a sample application which reads in 2 values from a textbox and writes it into a databse. This application works fine on my computer and the values are written to the database (In the connection string, I give my IP address as the datasource so that anyone on the internet can hit this database). However, when I copy this application to another computer and try to run it, it gives me an error "SQL Server does not exist or access is denied." I know this is a minor problem with some setting, but I haven't been able to find the solution on the internet. Can someone whose worked with Microsoft SQL Server 2000 please help me out.

Hi all,
I take error 610 "Maximum number of databases that may be accessed by a
transaction is 8. This number has been exceeded by this query" when I
execute a SELECT query.
In this query there are about 12 sub-query.
How can I fix the problem?
Thanks in advance.
For anyone with a larger number of databases (500+): How many do you have in a single instance. If you are using multiple instance on a single server, how many dbs per instance. This is why I'm asking
We are experiencing 701 "out of system memory" and temporary (usually) system freezes when the error occurs. We have 32bit 2005 version 9.00.2153.00, 32GB of memory, AWE enabled, quad dual-core 3GHz hyperthreaded server. Nether the bPool or VAS show any pressure when the "out of system memory error" occurs. Since this error usually indicates a VAS problem we tried increasing VAS to 1GB w/the -g flag. It made no difference. PSS has been working on the case for 3 weeks. They dont seem to be finding any evidince of memory pressure either. When I last spole to the escalation engineer yesterday it seemed that they are going to recommend reducing the number of databases on the server. I asked for clarification as to whether we are hitting a 32 bit barrior, an instance limitation, or both. I am awaiting the answer. How many databases do you have on your server? We had between 1700 and 1900 (the number varies) at times when the error occured. We are now at 1500, and have not had the error in the 2 days since reducing the number of databases...

I've just started to learn to use Visual Studio, and has come to database access.
I ran into this errormessage:
access denied for user <machine name>ASPNET
The book I'm using just only say that I have to grant the ASPNET user account permissions before the Web application will have access to a SQL database. ... Seems clear at first glance ... but I lack a "how to" ...!
---
I've tried to search the net for solutions ... several thousands of pages came up ... indicating that I'm far from the first who have this problem. ... So after I now have spend hours reading, without finding any useful ansver to the question. ...
So let me just tell the most popular answers. (So You don't repeat something I allready have read hundreds of times.):
This question has been asked before
Yes, true answer, but it doesn't help.
See the FAQ
If it was stated were in the FAQ to look it could have been useful.
Use something called "enterprise manager" (WIN XP pro, don't have this, though.)
I use WIN XP pro, so that answer dosn't help me either.

Hope some one can help.

I have created a PPC application that uses ADS to synchronize my sqlce db with a desktop MS Access database. It works fine on my computers, but my client cant get it to work on his. Here is the situation.
His "Computer Name" as it's stated in his 'My Computer' properties is "PAVSGP024FE.NWFSC.NOAA.GOV"
However his Access.MDW File is located in the directory "C:Documents and SettingsJoe NobodyApplication DataMicrosoftAccessSystem.MDW".
There is no directory called "C:Documents and SettingsPAVSGP024FE.NWFSC.NOAA.GOVApplication DataMicrosoftAccessSystem.MDW".
His current config.xml file looks like this.

He has tried adding port 1024 as an exception for his firewall settings, has installed Access Database Synchronizer on his computer, and I have also tried using the "long" computer name as the url setting in the config file. (i.e. <URL>http://PAVSGP024FE.NWFSC.NOAA.GOV:1024/</URL> but this throws the error

Hi
I’m looking for an efficient way of using a singe set of stored procedures to access a number of different databases (Sql Server).
The most feasible option I’ve come up with so far is to send the specific database name through as a parameter. Unfortunately the function “use” isn’t available to stored procs, so it seems I must move the query into a varchar, to then exec it.
There’s been another suggestion of using a web service to store the procedures, but I imagine that this would be very slow and cumbersome.
There must be a better way – any ideas?
Thanks,
indra
In MS Sql Server 2000, if you run a stored procedure that query's morethan 8 databases, you get this error gets raised:Maximum number of databases used for each query has been exceeded. Themaximum allowed is 8.In 2005, does this maximum number still exist? if so, is it still 8, orhas the number been increased?Thanks,Mike

We just installed an application, WhatsUpGold, to monitor our servers. Management won't let me host that on my primary SQL box. So, we are using MSDE on the local machine (call that box my_netmon).
I can access the db with very basic functionality using osql while on the my_netmon machine. I've added my domain user account as a System Admin using the following commands.
exec sp_grantlogin @name
go
exec sp_addsrvrolemember @name, 'sysadmin'
But when I go to the my_sql machine and try to attach to it with Enterprise Manager I get an error that the server does not exist.
What gives??? Is it just not possible, or am I missing something here?
My goal is to just be able to see the data stored in the MSDE db. Write views, etc...
Please advise,
Marc
I have a new problem with doing a restore of a number of databases using powershell. The script I'm using is based mainly on this one (Part 2 in particular): [URL] .....
The problem I'm having is around the RedgateGetDatabaseName function. My hunch is that its down to the different version of red gate and how sqlbackup works. Basically when the call is made to the function it is returning both the Database Name and the number of row's that the SQL command in the function has ran. I've tried to include a SET NOCOUNT ON at the start of the SQL command in the function but its still returning the now count.
I believe to configure maximum number of replicas it is required to have 5 nodes (1 Primary & 4 Secondary replicas). But how many databases can be included in one availability group, it think it is 32767. When I am referring to below URL it is mentioned something like "An availability group supports a set of read-write primary databases and one to eight sets of corresponding secondary databases. " What does this 'sets' means, is that maximum limit for only eight databases or maximum groups should be eight?

I am trying to enable database mirroring for 100 database.
It goes error free till 59 databases (some times 60 databases) with the
status (principal, synchronized) on principal. on the 60th or 61st database
it gave the status (principal, disconnected). Also mirror starts acting
abnormal. connection to mirror starts to give connection timeout and it is
not enabling database mirroring on any more databases. I have SQL SERVER
2005 Enterprise with SP1 on the servers. witness is not included yet.
this are my test servers... i have more than 500 databases on my production
servers.
principal and mirror both are using port 5022 for ENDPOINT communication.

principal and mirror both are using port 5022 for ENDPOINT communication.
All of the databases are critical and all must be included in the Database Mirroring.
so, after that I tried to implement database mirroring again......
System has 3 GB of RAM, SQL SERVER (Mirror) using 85 MB of RAM but still
giving this error while trying to enable database mirroring for 37th
Database.....
"There is insufficient system Memory to run this query"
WHY?
I have a 2 node cluster having 4 cores each wherein having 3 instances of SQL 2008 R2 enterprise comprising of 60 databases, 20 on each instance. I need to setup mirroring for each of the databases to a secondary server having 4 cores and 3 instances.
What i understand is that in this case the mirror server will be providing max of 512 worker threads and the 60 mirror databases would consume 240 threads.
What all needs to be checked for looking into the feasibility of going ahead with a async mirror setup as mentioned above.
For a field in a database to accept both text and number what 'Data Type' should I be using, i.e. 23t5
