• creating multiple users for a c#.net winform application using sql server express

  - by sqlchild

  i have a single sql database in sql server express. i have a login MAINLOGIN, for this database. i want insertion of data in this database through multiple users, U1,U2,U3, each having different userids & passwords. These users would be created by MAINLOGIN , manually or via the winform application. So while creating MAINLOGIN , i would give him permission to further create logins. For this what should i do? i cannot create MULTIPLE users, because for one database, only one user can be created under one login. so should i create multiple logins, L1,L2,L3, then map, U1, U2, U3 to them. Or, is there a better way to do this? like application roles etc. i dont want to use windows authentication. because if i know the system password, then i could simply connect sql via the application and insert wrong data.

• Tracing or Logging Resource Governor classification function behavior in Sql Server 2008

  - by nganju

  I'm trying to use the Resource Governor in SQL Server 2008 but I find it hard to debug the classification function and figure out what the input variables will have, i.e. does SUSER_NAME() contain the domain name? What does the APP_NAME() string look like? It's also hard to verify that it's working correctly. What group did the function return? The only way I can see this is to fire up the performance monitor and watch unblinkingly for little blips in the right CPU counter. Is there some way I can either run it in Debug mode, where I can set a breakpoint and step through and look at variable values, or can I at least do the old-school method of writing trace statements to a file so I can see what's going on? Thanks...

• SQL Server deadlock issue

  - by George2

  Hello everyone, I am using SQL Server 2008 Enterprise. I am wondering whether dead lock issue is only caused by cross dependencies (e.g. task A has lock on L1 but waits on lock on L2, and at the same time, task B has lock on L2 but waits on lock on L1)? Are there any other reasons and scenarios which will cause deadlock? Are there any other way which will causes dead lock -- e.g. timeout (a S/I/D/U statement do not return for a very long time, and deadlock error will be returned) or can not acquire lock for a long time but not caused by cross-dependencies (e.g. task C needs to get lock on table T, but another task D acquire the lock on table T without releasing the lock, which causes task C not be able to get lock on table T for a long time)? thanks in advance, George

• Sql Server Management Studio 2008 - Insert string with more than two lines

  - by gsharp

  I want to paste a string with more than two lines into a nvarchar(max) cell (right click a Table in Sql Server Management Studio 2008 -- Edit Rows). Unfortunately only the the first line of the string is pasted into the cell. I know, I could write a Insert/Update script for that, but it's not what I'm looking for. I need a quick way to paste some text into some cell. Is there a way to achieve my goal? Thanks in advance.

• Security of PHP script, embedded or otherwise

  - by typoknig

  Hi all, I am curious about the security of PHP on an HTML webpage where PHP code is embedded (a webpage that would exist on the server as "webpage.php") or on a PHP script that may be referenced by an HTML page (that is, a PHP script that is not actually part of a webpage that exists on the server as "something.php" and is referenced by "webpage.html"). Getting to the point, let us say that if the source code of my PHP script is known by anyone it would be a very big problem. I know that when you view the source of a PHP page in a browser the PHP script is not shown, but what if the PHP server failed and the HTML still loaded (is this even possible), would a user be able to see the PHP script? To be more general, is there ANY possible way that a user could access the source of a PHP script from a web browser, and if so, how do I prevent it?

• Microsoft SQL Server 2005/2008 SSIS are oversized

  - by Ice

  In this case i'm old style and loved 'my fathers DTS' from SQL 2000. Most of the cases i have to import a flatfile into a table. In a second step i use some procedures (with the new MERGE-Statement) to process the imported content. For Export, i define a export-table and populate it with a store proc (containing a MERGE-Statement) and in a second step the content will be exported to a flat file. In some cases there is no flat file because there is annother sql-server or in rare cases an ODBC-Connection to a sybase or similar. What do you think? When it comes to complex ETL-Stuff the SSIS may be the right tool...but i haven't seen such a case yet.

• SQL Server 2005 Weird varchar Behavior

  - by Tom Tresansky

  This SQL Server 2005 T-SQL code: DECLARE @Test1 varchar; SET @Test1 = 'dog'; DECLARE @Test2 varchar(10); SET @Test2 = 'cat'; SELECT @Test1 AS Result1, @Test2 AS Result2; produces: Result1 = d Result2 = cat I would expect either The assignment SET @Test1 = 'dog'; to fail because there isn't enough room in @Test1 Or the SELECT to return 'dog' in the Result1 column. What is up with @Test1? Could someone please explain this behavior?

• WebService Security

  - by LauzPT

  Hello, I'm developing an project, which consists in a webservice and a client application. It's a fair simple scenario. The webservice is connected to a database server, and the client consumes from the webserver in order to get information retrieved from the database. The thing is: 1. The client application can only display data after a previous authentication; 2. All the data transferred between Web Service and clients must be confidential; 3. Data integrity shouldn’t be compromised; I'm wondering what is the best way to achieve these requirements. The first thing I thought about, was sending the server a digital signature containing a client certificate, to be stored in the server, and used as comparison for authentication. But I investigated a little about webservice security, and I'm no longer certain that this is the best option. Can anyone give me an opinion about this? TIA

• Single SQL Server Result Set from Query

  - by JamesC

  Hi Please advise on how to merge two results in to one using SQL Server 2005. I have the situation where an Account can have up to two Settlement Instructions and this have been modeled like so: The slim-ed down schema: Account --------------------- Id AccountName PrimarySettlementId (nullable) AlternateSettlementId (nullable) SettlementInstruction ---------------------- Id Name The output I want is a single result set with a select statement something along the lines of this which will allow me to construct some java objects in my Spring row mapper: select Account.Id as accountId, Account.AccountName as accountName, s1.Id as primarySettlementId, s1.Name as primarySettlementName, s2.Id as alternateSettlementId, s2.Name as alternateSettlementName I've tried various things but cannot find a way to get the result set merged in to one where the primary and alternate FK's are not null. Finally I have searched the forum, but nothing quite seems to fit with what I need.

• Should I rebuild table indexes after a SQL Server 2000 to 2005 database migration

  - by Joe T

  I'm tasked with doing a SQL Server 2000 to 2005 migration. I will be doing a side-by-side migration. After restoring from a backup I plan to do the following: ALTER DATABASE <database_name> SET COMPATIBILITY_LEVEL = 90; DBCC CHECKDB(<database_name>) WITH NO_INFOMSGS DBCC UPDATEUSAGE(<database_name>) WITH NO_INFOMSGS exec sp_updatestats ‘resample’ Should I rebuild table indexes before using DBCC UPDATEUSAGE and sp_updatestats? Have I missed anything obvious that should be executed after a migration? All help would be warmly up-voted. Thanks

• SQL Server Express: Failed to add primary key after creating a database table

  - by Syd

  Scenario: I have created a database table. And when I tried to add a primary key (using the SQL Server Management Studiio) to the table, it failed with an error message "Saving changes is not permitted. The changes you have made requrie the following tables to be dropped and re-created. You have either made changes to a table that can't be recreated or enabled the option Prevent savign changes that require the table to be re-created." The environment is Windows 7. I have earlier installed it on a Windows XP SP2 and it worked. And yes, my table is empty (freshly created). My current workaround is to run the "Drop and Create" script. The other alternative is to create the primary key before I save the table. Is this a bug or a limitation with the Express version?

• Creating audit triggers in SQL Server

  - by Mike C.

  I need to implement change tracking on two tables in my SQL Server 2005 database. I need to audit additions, deletions, updates (with detail on what was updated). I was planning on using a trigger to do this, but after poking around on Google I found that it was incredibly easy to do this incorrectly, and I wanted to avoid that on the get-go. Can anybody post an example of an update trigger that accomplishes this successfully and in an elegant manner? I am hoping to end up with an audit table with the following structure: ID LogDate TableName TransactionType (update/insert/delete) RecordID FieldName OldValue NewValue ... but I am open for suggestions. Thanks!

• Upgraded AGPM Server cannot connect to relocated archive

  - by thommck

  We were using the Advanced Group Policy Management (AGPM) v3.0 on out Windows Server 2008 DC. It kept the archive on the C: drive. When we upgraded to AGPM v4 we relocated the archive to the D: drive. Now when we try to look at a GPO's hisory in GPMC we get the following error Failed to connect to the AGPM Server. The following error occurred: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs. System.ServiceModel.FaultException (80131501) You are able to click Retry or Cancel. Retry brings up the same error and Cancel takes you back to GPMC and the History tab displays "Archive not found". I installed the client on a Windows 7 computer (which is a n unsupported set up) and it could read the server archive without any issues. I followed the TechNet article "Move the AGPM Server and the Archive" but that didn't make a difference How can I tell the server where the archive is?

• VSS Post Backup failures for Virtual Server 2005 R2 SP1 virtual machines

  - by califguy4christ

  We've been seeing strange errors with Volume Shadow Copy services on our Virtual Server 2005 R2 SP1 host. It appears to be failing on a strange mountpoint in the C:\WINDOWS\Temp\ folders, which I believe is used by VSS to mount a writeable image file. To summarize: The Microsoft Virtual Server 2005 Writer continually goes into a failed retryable state The Virtual Server log reports errors during the Post Backup phase VSS reports errors backing up a mount point of unknown origins The mount point causes NTFS and ftdisk errors The host is x86 Windows Server 2003 Standard, SP2. The virtual machine is the same. Both use basic disks. Here is the writer state: Writer name: 'Microsoft Virtual Server 2005 Writer' Writer Id: {76afb926-87ad-4a20-a50f-cdc69412ddfc} Writer Instance Id: {78df98e2-bf19-4804-890b-15865efef3bd} State: [11] Failed Last error: Retryable error From the Virtual Server log: Virtual Server - Vss Writer - Event ID: 1035: The VSS writer for Virtual Server failed during the PostBackup phase. The guest shadow copies did not get exposed on the host machine, after mounting all the virtual hard disks of the virtual machine VMACHINE. From the Application log: VSS - None - Event ID: 12290: Volume Shadow Copy Service warning: GetVolumeInformationW( \\?\Volume{fb84bae7-87f5-11dd-9832-001cc4961ca6}\,NULL,0, NULL,NULL,[0x00000000], , 260) == 0x0000045d. hr = 0x00000000. From the System log: Ntfs - Disk - Event ID: 55: The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume C:\WINDOWS\Temp\ {fb84bae7-87f5-11dd-9832-001cc49.... My current theory is that VSS creates a mount point for an image file of the VHD, then the software panics for some reason, leaving everything in an inconsistent state. Removing the mount point doesn't resolve the problem. All of the other disks check out fine with CHKDSK. There's no exclusion option for VHDs or to turn off online backups. Has anyone seen this kind of thing before or point me in the right direction for getting more information about the mount point and it's origins? I haven't been able to trace what application is creating that mount point.

• Can’t connect to SQL Server 2008 - looks like Shared Memory problem

  - by user38556

  I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio. I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message: A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233) Why is it returning a Named Pipes error? Why would it not just use Shared Memory, as this has a higher priority order in the list of connection protocols? It seems like it is not listening on Shared Memory for some reason? When I set Named Pipes to enabled and try to connect, I get the same error message. My windows account is does not have administrator priviliges on my computer - perhaps this is making a difference in some way (as some of the discussions in this post about an "SuperSocketNetLib\Lpc" registry key seems to suggest). I have tried restarting the SQL Server service, by the way, and also tried to get someone to log onto the machine with an admin account to restart the SQL Server service. Still no luck.

• PXE bootable image for terminal server?

  - by HeavenCore

  We have 300 windows xp machines on cruddy old hardware across the company. With extended support for XP ending April next year we're looking into our options. Couple of options: Replace the 300 PC's with full windows 7 PC's (£100k +?) - no use of terminal server (our current model) Replace the 300 PC's with off the shelf thin clients & make use of our terminal server - Cheaper clients but Terminal Server CALS required? Keep the 300 PC's, replace windows XP with linux thin client capable of connecting to our terminal server - no hardware costs, just Terminal Server CALS required? Keep the 300 PC's - remove hard drives and make use of a PXE bootable "thin client" to connect to our terminal server If we were to choose option 4, what our the options out there? Is there any official PXE bootable thin clients for terminal server out there? If so, what are the licence requirements? Is there options we haven’t considered? There must be lots of companies out there in this situation - curious what the current trend is for this problem? Edit: Option 5 - Create a bootable Windows PE image with RDP auto start and use that as a "thin client" for our terminal server - is Windows PE licence free in such a model?

• Is one server on a vlan unnecessary?

  - by moomoochoo

  DETAILS I've been researching web hosting solutions in Japan. Based on this question one of the services available seems to be a VLAN. I've read about the advantages of such a system for a large organization, but there doesn't seem to be much information regarding smaller setups. I take that to mean that for one server it is likely to be unnecessary? My concern is that I don't know how many other servers are on the WAN, so regardless of how many servers I use a VLAN might still be a good idea. SERVER INFO One dedicated server would be used. It would not be virtualized. My Research so far Based on comments here, a VLAN would be useful for mitigating these problems. A user on another server could, either mistakenly or maliciously, assign one of your IP addresses to their server, resulting in a "duplicate IP" situation that would cause connectivity issues. A user on another server could poison the arp cache and potentially redirect traffic to snoop on communication intended to/from your server. (later in the discussion this point was said to be unrealistic.) QUESTION Is it worthwhile getting a vlan for one dedicated server? Will it be easier/the same/ harder to manage?

• Windows Server 2008 32 bit & windows 7 professional SP1

  - by Harry

  I'm testing my new Windows Server 2008 32 bit edition (2 servers) as a server and Windows 7 professional 32 bit as a client. Let say one is a primary domain controller (PDC) and the other is a backup domain controller (BDC) like the old time to ease. Every setup were done in the PDC and just replicate to BDC. Didn't setup anything, just install the server with AD, DNS, DHCP, that's all. Then I use my windows 7 pro 32 bit to join the domain. It worked. After that I tried to change the password of a the user (not administrator) but it always failed said it didn't meet the password complexity setup while in fact there's no setup at all either in account policy, default domain policy or even local policy. Tried to disable the password complexity in the default domain policy instead of didn't set all then test again but still failed. Browse and found suggestion to setup the minimum and maximum password age to 0 but it also failed. Tried to restart the server and the client then change password, still failed with the same error, didn't meet password complexity setup. Tried to see in the rsop.msc but didn't found anything. In fact, if I see the setup in another system with windows server 2003 and windows xp, using rsop.msc I can see there's setup for computer configuration windows settings security settings account policies password policy. I also have a windows 7 pro 32 bit in a windows server 2003 32 bit environment but unable to find the same setting using rsop but this windows 7 works fine. anyone can give suggestion what's the problem and what to do so I can change my windows 7 pro laptop password in a windows server 2008 environment? another thing, is it the right assumption that we can see all the policies setting in windows 7 whether it's in a windows server 2003 or 2008 environment? thanks.

• Mac OS X Server add server user

  - by Meltemi

  What's the recommended way to add a user to Mac OS X Server that doesn't need all the hoopla associated with Workgroup Manager? There are many users pre-configured in Mac OS X Server (www, root, ldapadmin, etc.) that don't have "Full Name" or mail accounts, etc. I'd like to create a 'svn' user to be the owner of our Subversion Repository as per this tutorial: If you've decided to use either Apache or stock svnserve, create a single svn user on your system and run the server process as that user. Be sure to make the repository directory wholly owned by the svn user as well. From a security point of view, this keeps the repository data nicely siloed and protected by operating system filesystem permissions, changeable by only the Sub- version server process itself. Wondering if there's a way outside of WorkgroupManager and OpenDirectory as this account will be entirely server based. Is this still sound advice under OS X Server? If so what's the easiest way to create the user (Mac OS X Server doesn't seem to respond to useradd).

• Windows Server 2003 SBS domain in multiple sites

  - by E3 Group

  We have about 25 employees in our current office and are looking to open up another office in another capital city housing about 15 employees. In our current office, we are running a domain hosted by a 2003 SBS server and I've been tasked by the boss to expand our infrastructure to the new office in the cheapest way possible (cheapest way in the short run that is, because my boss doesn't think more than 6 months ahead). So I'm looking to get a second hand server and have it run Server 2003 Std with exchange server 2003. These are the things that it needs to do: Replicate shared folders that are hosted in the parent LAN. Deliver emails hosted in the parent Exchange Server Somehow link up with the parent domain controller and push the AD to the remote site I'm pretty sure 3 is impossible but the DC would be available if a VPN connection is present, right? On that note, would I be looking at hardware VPN connections? I'm not sure how to deploy the new site as this is my first time doing it and i'm making it especially difficult for myself, seeing as the AD and DC is on an SBS server. Would I first start by establishing a VPN connection and then joining the new server to the domain? Will things 'just work' if I install exchange onto the new server and point outlooks to it? and how would I be able to replicate shared folders?

• How do I connect a 2008 server to a 2003 server active directory?

  - by Matt

  Our DC is running Windows Server 2003. I've just set up Windows Server 2008 and have terminal server running on it. When setting the terminal server permissions, it was able to allow a group name that was read from the domain. In the DC the new terminal server shows up as a computer in the domain. I can also log in as a user within the domain even though that user doesn't exist locally on the new server. However, when I go to set sharing permissions on the new machine it doesn't show my domain as a location. Instead it is only looking at location "machinename" and not allowing domain to be seen or added. Is there something I'm missing? Ok, lots of errors in the event log. We have this: The winlogon notification subscriber is taking long time to handle the notification event (Logon). Followed by this: The winlogon notification subscriber took 121 second(s) to handle the notification event (Logon). Followed by: The processing of Group Policy failed because of lack of network connectivity to a domain controller. This may be a transient condition. A success message would be generated once the machine gets connected to the domain controller and Group Policy has succesfully processed. If you do not see a success message for several hours, then contact your administrator. I think this might be the same problem I'm having http://serverfault.com/questions/24420/primary-domain-controller-slow Solved. The issue was that I had changed from DHCP to static and put the wrong DNS server IP in. i.e. firewall instead of DC/DNS server.

• Windows server 2008, Dns. I'm confused

  - by Dejan.S

  Hi. I recently setup a window server 2008 server at work. Keep in mind I have never worked with it before:). Background story is I try to host a couple of sites on the server through iis7, I got domains (currently hosted at other hosters for the moment). I want to point the domain NS to my server on all of them. I have read how to setup a DNS on the server, so far so good. now my dns is companyname.com in the server manager I got DNS / companyname.com in there I got ns.comanyname.com, in there I got Host(A) with the server ip now this is where I get confused about how things work with DNS, NS & Host(A). I dont know how to assign(so to speak) the Host(A) to one of my webapps hosted on the iis7, because that is the pointer right?. To leave an example to work with lets say, Hosted.com is hosted on my iis7, on port 81. You don't understand how great full I would be if somebody could explain this confusion. EDIT: Do I need to create a DNS for every site hosted on my server? Or just make a A Host/Record? Thanks guys

• Remote Desktop *from* Windows 2008 R2 Server

  - by freefaller

  Summary: how do I create an RDC connection from a Windows 2008 server to another server? Our client will only allow us to connect to their server via a static IP address (which is fair enough), but unfortunately as we're a very small company we don't have one in the office. As a work around, we had the connection working through our old Windows 2003 server (dynamic-cloud from 1and1). .. however we have just rebuilt the server to run under Windows 2008 R2 (don't ask, but it was necessary), and now I simply cannot get the connection working. I have added an "Outbound Rule" to Windows Firewall with Advanced Security (TCP, All local ports, 3389 remote port - I have also tried the other way around). I have added a packet filter IP security rule with the same details. The 1and1 firewall rules (through their online control panel) allows for 3389 TCP and UDP. But it is simply not connecting (yes, the server is definitely on and able to accept connections) with the general error of... Remote Desktop can’t connect to the remote computer for one of these reasons: 1) Remote access to the server is not enabled 2) The remote computer is turned off 3) The remote computer is not available on the network Is there anything obvious I've missed - or something I can use to find out where the request is being blocked? The new server is using the exact same IP address as before, so I don't believe that would be an issue. Unless it's trying to use an IPv6 address rather than the old IPv4 address that it was before? I apologise that I am not a network person by trade, but I know more than anybody else in my office!!

• Ubuntu karmic, chroot, Ubuntu server 8.04 LTS and Plesk

  - by morpheous

  I am pretty new to the Linux environment, and although I have been using Ubuntu Karmic desktop for development work, I have always prefered the GUI tools and very rarely use the terminal. I am about to launch a site (a VPS) which will be running Ubuntu server 8.04 LTS and Plesk. I want to install both the server (8.04 LTS) and Plesk in a 'chroot' on my Karmic desktop. I also want to test install some packages I have written for the server, and generally familiarize myself with the environment before I signup to the hosting service. I will be running a streamline server (no GUI), with only the following software: PHP Python mySQL PostgreSQL Apache Plesk Third party packages I developed In terms of mail, I think the hosting provider provides a mail service, so I dont know if I will need to run my own mail server. I will like some advice on the following: How can I install Ubuntu 8.0.4 server LTS in a chroot? How can I install Plesk in Ubuntu 8.0.4 server LTS (from the command line) Can anyone recommend how I back up the remote server when I go live (i.e. what tools to use)?. I will need to back up both databases, as well as some config data and installation packages
