We are using sql server 2000
Problem:
========
A few records in a particular table are getting updated with incorrect values everyday somehow by some process. No one is manually changing these records.
Every morning I query the database and fix these records. But somehow they again get set to the incorrect values.
So I want to figure out how this is happening. I'm thinking of creating an update trigger on that table. And whenever this update trigger is fired, check the modified record's id and if it is the problematic record, then get the hostname, username, processid which is doing this update.
Can someone give me ideas on how to get the hostname, username.
Any other ideas are also appreciated
Thanks in Advance!

Hi everyone,
ON SQL 7.0
I want to capture hostname of the client computer making changes to a table on the server. I tried to use sysprocesses table, but the max(last_batch) column is giving the datetime and hostname of previously ran query. I need to find the hostname of the client who is making change at that instant of time.
Can anyone help me.
Thanks

Hi,
Question:
How do I get the hostname from the instance name please?
My present design at present is something as follows:
We have several sql server 2005 machines
i.e.
ServerSQLA, ServerSQLB, etc....
Each machine may have one or more instances,
i.e.
ServerSQLAinstace1
ServerSQLAinstace2, etc...
The server name in this case is ServerSQLA
Instance naming and node convention is different for clusters
i.e.
C_ServerSQLAinstance1
C_ServerSQLAinstance2
on the node(s):
N_ServerSQLA or N_ServerSQLB
Thanks

Hi!
Can something tell me how I can obtain the machine name (either IP address or DNS name) on which SQL Server is running via a SQL query?
select @@version returns a lot of useful information, however it doesn't return the host name.
thanks in advance

Hello all,
I'm having trouble with my Merge Replication setup in regards to changing the HostName property of the SqlCeReplication object. As we all know, if you modify the HostName value, you must then call the ReinitializeSubscription(true) method before calling Synchronize(). Unfortunately, this isn't working for me. Following this sequence of steps consistently results in error messages saying that I need to either call ReinitializeSubscription, or change my HostName back to it's original value. Has anyone ever experienced this problem?
Regards,
Rob Tiffany

On SQL Server 6.5, we tried to track down the owner of a process,which was hogging the CPU. Using Currently Activity Detail, we went to the hostname that seemed to be the culprit, but the users had not accessed SQL Server in a few days. Where is SQL Server get the hostname from? We are on an NT4.0 network, using DHCP.

Hi everyone,
my SQL is running TCPIP and everytime I register the server from a client, I have to enter in the IP address. Can I use a hostname to map an IP address to a server name and then enter the server name to register the server?
Thanks..Binh

In SQL2005, is it possible to restrict incoming sql or windows authentication logins by source hostname or IP address? Perhaps using endpoints?
We are currently using hosts file on the db server as a temporary solution, but the SA will not allow us to use this as a permanent solution.
The app team I support is asking me to build an "idiot proof" database so that an Dev or Test app server they may configure, doesn't unintentionally connect to the Production database and damage/alter data.
Don't worry, I've already asked if they can't follow some kind of M&P's to prevent this kind of silly behavior, but they insist on DBA team creating a bullet-proof database that can outsmart app developers who try to attempt something dumb like this.
Any ideas or suggestions would be greatly appreciated.
TIA,
Phil

In an Insert Into statement I have used the Host_Name() function toidentify which user has suppied a record to a table that holdstemporary data.I'm using an Access2K front end.Code:Alter procedure SPName@parameter1 intASSet nocount OnSet xact_abort offDeclare @myHost nvarchar(50)Set @myHost = Host_Name()Insert Into tblMyNameTEMP(UniqueID, AnyField1, AnyField2,myMachineName)SELECT tblMyName.UniqueID, AnyField1, AnyField2, @myHostFROM tblMyNameWHERE tblMyName.UniqueID = @parameter1I have two problems.In some cases (and only on one or two of maybe about 250 clientworkstations) Host_Name() returns the name of MY machine. I'm thinkingthis is because I developed the app and distributed it and for somereason it's retaining the info contained in my original connectionsetup set in the MS-Access Connection window???Also, on some occasions, I get blocking messages in my trace logfollowing this operation.Any help on these two issues is appreciated.lq

We are attempting to improve our merge replication process between our SQL Server 2005 server and SqlCe Mobile 3 client by switching to Data Partitions. We are using IIS as a proxy to SQL Server 2005 running on a different box using a DOMAIN account.
We've setup row filters to use HOST_NAME() and have set the option "Automatically define a partition and generate a snapshot if needed when a new Subscriber tries to synchronize" to true in the Data Partitions options under the publication's properties in SQL server management studio.
If I use a .HostName value of "1234", everything works fine. A subdirectory is created under a our publication's folder in the shared replication directory that relates to the host_name. Data is copied to the device and can be observed through query analyzer that the data is in fact filtered properly.
However, when using a .HostName based on the GetDeviceUniqueID (which results in '3D321F7212B2AD2CC824954662B9023441BB2D20'), replication works sometimes and sometimes fails with "The merge process was unable to deliver the snapshot to the Subscriber. If using Web synchronization, the merge process may have ben unable to create or write to the message file. [etc]". The final HRESULT is 80045017.
While this error indicates a permission problem, there were no permission problems when creating the "1234" partition. In researching the problem, I ran across KB905395 which states:
Limitations on the HostName property and the Subscriber-requested snapshotIf you try to initialize a SQL Server Mobile Edition subscription by using a filtered HostName property, initialization fails. This problem occurs when the value that is supplied for the HostName
property contains more than 12 characters. To work around this problem,
disable Subscriber-requested snapshot delivery at the Publisher. You
can also use a value for the HostName property that contains fewer than 12 characters.
====
This seems to be consistent with what we've observed (which actually led to the "1234" test). Does anyone know if a fix for this exists? Has anyone else run across this issue? I saw a previous post from March that did, but never got resolved. However, the KB article above was posted in March - hmmm...
This is an existing application and filtering based on the device's id is ingrained in the application. Changing it now would be large undertaking.

Not sure if this is relevant here but I thought someone might have seen this.
I am trying to set up Express edition as a mirror witness and am running into a problem.
It seems the express instance thinks its "Host Name"[1] is foo-prod-witnes rather than it's real name foo-prod-witness (notice the additional "s")
When I try to create the security endpoints everything appearsd to work as far as connecting to the express instance but i cannot start the mirror because the address listed is
TCP://foo-prod-witnes:5022 (not a valid hostname)
My enterprise editions report foo-prod-sql01.fqdn:5022
Any ideas how to fix this?

Hello,
I am using Merge replication for synching data between SQL Server 2005 and Mobile units (SQL CE 3.5). I have created one publication and there are around 300 subscribers in the production.
If I want to use a HostName() filter so that each user gets his or her own data, do I have to set up 300 different subscriptions with different HOSTNAME values or can I use the same subscription somehow?
I would appreciate if someone can let me know whats the best way to approach this problem.
Thanks

Hi,
Can anyone help, how to find client's hostname using RDP from MSSQL command.
In simple words,
I am connecting to Remote desktop and using MSSQL server management studio in the remote desktop. And when I run select host_name(), it returns the RDP machine name. However, I wish to see my own computer name.
Thanks in advance.

We've got x2 data centers in the US:
NYC & SAC
Sadly the hostnames for the boxes I am trying to replicate are similar:
- db1.nyc.mydomain.tld
- db1.sac.mydomain.tld
The servers can talk to each other over all necessary ports however when I generate a push subscription from the publisher, I am asked to add the SQL Server subscriber and it already shows DB1 listed since itself is DB1.nyc. How can I attach the remote subscriber when setting up the subscription from the publisher if the hostname conflicts in my unique scenario?I created a entry on the publishers host file to use db2sac for the SAC IP and entering that alias in as the remote subscriber but no dice.

When using the MS SQL 2005 JDBC driver, I now need to have the DNS nameresolution to the client correctly set up. If not I get the followingerror:SQLState: 08S01SQLError: 0Message: hostname : hostnameWhere "hostname" is the client host name. It doesn't seem to matter ifIuse an IP address or hostname in my connection URL. When searching thenet,I have seen a similar error, but not exactly the same, where themessage is"Hostname: hostname not found" (once again, here "hostname" is theclientmachine) where they suggested the issue was the DNS name conflict.I found the error goes away if the client machine's hostname match theDNSname used for the same IP addess that the DB server is using. Onework-around is to set hostname on the client to the IP address beingused.I know the right thing to do is set the hostname and the DNS namelookup thesame, but I have a customer who doesn't want to do this. They didn'thave tofor 2003, and they don't want to for 2005. Sigh. Is there a way todisablethis feature?

Hello all - this has now happened to me on a few occasions (different installs, different sites, etc.), but my client PCs cannot access Report Manager by the server's hostname (even though I can ping by hostname from the client).
For instance, if I try:
http://ovenserver/reports
I get the infamous "Internet Explorer cannot display the webpage" message.
If I try:
http://10.0.0.20/reports
The Report Manager loads properly without a hitch.
I know I am missing something simple here - can anyone help?
Thanks!

We have a 2 servers with 2 default instances,
Environment- SQL server 2012 SP2 | Windows Server 2008 R2
1server:
hostname-serverA , Instance-serverA and port-2040 Ip-192.164.1.1
2server:
hostname-serverB , Instance-serverB and port-2040 Ip-192.164.1.2
If i do a SSMS connection-the possible connections strings which can be used to connect to Instance "serverB" should be,
a.serverBserverB
b.serverB,2040
c.192.164.1.2,2040
Note: but even the connection string "serverBserverA,2040" also connects to Instance "serverB", when i try to connect from SSMS, In SSMS it shows the wrong instance name like, "serverBserverB", but it actually connects to Instance "serverA"
i.what is the reason behind this?
ii.Is there any way to avoid this connection, by performing server property changes, if any ?

The command sqlcmd seems to fail when using trusted connection and an IP address or a fully qualified hostname. For example:
sqlcmd -E -S nnn.nnn.nnn.nnn
where nnn.nnn.nnn.nnn is the real IP address of the machine, or
sqlcmd -E -S hostname.domain.com
where hostname.domain.com is the fully qualified hostname of the machine, gives the error:
Msg 18452, Level 14, State 1, Server 380GX280B05, Line 1
Login failed for user ''. The user is not associated with a trusted SQL Server c
onnection.
On the other hand, sqlcmd -E -S 127.0.0.1 works, and so does sqlcmd -E -S hostname, or sqlcmd -E -S tcp:hostname,1433.
This is on a clean machine, with SQL Server 2005 freshly installed as Administrator with mixed authentication, and the test runned also by Administrator.
Is it normal or is it a bug?
Thanks.

I currently have the following connection string set up in Excel to connect to my SQL db:
Provider=SQLOLEDB.1;Persist Security Info=True;User ID=XXXXXX;Initial Catalog=YYYYY;Data Source=SQL;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=PROJMNT1;Use Encryption for Data=False;Tag with column collation when possible=False
What I would like to do is replace the Workstation ID (which apparently is hard coded?) so that the user's workstation name pulls (%COMPUTERNAME%) so that I can see who is connecting, using what, for how long etc etc.
Is there anyway to accomplish this?
