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 ?

Hello,
I've a simple 2 nodes clusters active/passive with SQL2005SP2, using a named instance.
I can access from a remote workstation using <servername>,Port# but not <servername><instance>
Any idea why?
SQLBrowser is running and protocol is enable.
If starting sqlbrowser.exe -c I see the request but there don't seem to be any response.
Thank

I've installed SQL2005 on a server already running SQL2K on my laptop. SQL2K is the default instance, so I'm trying to connect to SQL2005 using MYSERVERSQL2005 as the instance.
The steps that I've taken are to apply SP2 and enable remote connections (TCP & Named pipes). I've also made sure the SQL Server Browser service is running and enabled.
The error message that I get via SQL2005 client tools is "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) (Microsoft SQL Server, Error: -1)"
I dont understand as to why i am unable to connect to 2005.
Any ideas?

Problem: I upgraded a SQL Server Express instance to SQL Server Enterprise, but I'm unable to connect to the SQL server from any remote machine. Only local connections work -- and I've verified that Remote Connections are allowed in the SQL Surface Confg. utility.
Scenario: Server1 has an SQL Enterprise edition installed as a default installation. SharePoint Server 2007 was installed later, and during that install a SQL Express edition instance was installed which is part of the standard SharePoint install. That Express instance contains all the SharePoint content databases.
So Server1 has SQL instances:
Server1 <default install running Enterprise>
Server1OFFICESERVER <previously running SQL Express, now upgraded to Enterprise>
After upgrading Server1OFFICESERVER to Enterprise, everything seemed to work fine (i.e. SharePoint works fine). However when I try to connect remotely to Server1OFFICESERVER I can't. I've verified through the SQL Surface configuration tool that remote connections are allowed. I've rebooted the server as well. I've tried connecting remotely using various PCs and various applications (e.g. SQL Server Mgmt Studio, Visual Studio, etc.).
Any other ideas to try?

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.

We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?

I have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.
In order to do that, I have taken the records based on the fragmentation %.
But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.
create table #fragmentation
(
FragIndexId BigInt Identity(1,1),
--IDENTITY(int, 1, 1) AS FragIndexId,
DBNAME nvarchar(4000),
TableName nvarchar(4000),
[Code] ....

After reading some comments here I decided to look at tables to see if any had a clustered index that was a unique identifier. Yep. So if I have a table with a unique identifier as the primary key/clustered index and an identity column that is indexed, I would like to make the identity a clustered index (maybe even the primary key) and make the unique identifier a unique non-clustered index (not the primary key).
Does this sound reasonable?If I do this will I need to drop and recreate the other indexes? Or maybe just rebuild the other indexes?
Currently:
CREATE TABLE Payments (
IDX INT IDENTITY(1,1) NOT NULL,
GUID UNIQUEIDENTIFIER NOT NULL DEFAULT(NEWID()),
.....
-- many other columns
);
GO
ALTER TABLE [dbo].[PAYMENTS] ADD CONSTRAINT [PK_PAYMENTS_GID] PRIMARY KEY CLUSTERED ([GUID] ASC);
GO
CREATE NONCLUSTERED INDEX [IX_Payments_ID] ON [dbo].[PAYMENTS] ([IDX] ASC);
GO
Would like:
ALTER TABLE [dbo].[PAYMENTS] ADD CONSTRAINT [PK_PAYMENTS_IDX] PRIMARY KEY CLUSTERED (IDX ASC);
GO
CREATE UNIQUE NONCLUSTERED INDEX [IX_Payments_GUID] ON [dbo].[PAYMENTS] (GUID ASC);
GO

I am extremely new to database design, and I ran into a problem that I know comes up often, however has many opinions...
Basically I have a table that is going to have 50+ columns. The natural key on this table is actually 8 columns wide, 4 of them being Varchar columns by default. (varchar(50)'s).
I have added an identity column, (1,1) to the table, however I put the clustered index on the 8 natural keys... My plan is to rebuild the clustered index once nightly when the system isn't in use (after 7 pm).
I know others would say it would be better to have the clustered key on the 1,1 column and then add indexes on the other 8 fields... However I don't quite understand why honestly...
Every single query against this table will use the 8 columns, and will NOT use the Identity column (1,1) because they are calls from other systems that do not know the Identity column....
Therefore if your database is set up for query speed, and every single query has to have a value for 8 columns to get a valid result, does it make sense to put a clustered index over the 8 columns?
If not why? Why is putting a clustered index on an identity column (that will literally never be used in a query) a better solution?

What is the best way to forecastestimate space for non-clustered index on a table?
Example :
Table name : Test123

Reserved : 18000000 KB
Data : 70000000 KB
Index: 40000000 KB
Note: Test123 already has clustered index and 2 non clustered indexes.

I have installed SQL Server 2005 on two boxes and installed client tools only on my local machine.
I cannot connect to either machine.
I also have the "Error 26 problem - does not allow remote connection etc."
Of my two remote servers, one is virtual the other is not.
I cannot establish a connection through the "Microsoft SQL Server Management Studio" tool on my local machine using:
Severname: ServerNameInstanceName
Authentication: Either Windows or SQL Server
Eveything is enabled (TCPIP, Name Pipes), no firewall
SqlBrowser is running
I have SQL Server 2000 also installed on the same server machines and I am able to connect to this.
I tried using IP addresses and port numbers as follows (NB ServerName implies alias or ip address) and portnumbers I have tried are 1433 and 1766:
ServerName,portnumber
ServerNameInstanceName,portnumber
It either connects to the 2000 or gets the error 26 problem.
Any help would be appreciated.

I upgraded my 6.5 server to 7.0 two days ago running into small problems with the database upgrade wizard. I had some small problems with security which took me some time but was not that difficult once I figured it out. I then proceeded to switch back to 6.5 mode to transfer all the data that had been done that day to my development machine so I could then import it to the SQL 7.0 version. When I was done with the transfer I switched back successfully, started the server successfully, but I was unable to connect. I get the error "Connection could not be established...", so after several attempts to connect and shuting the server down I now am at a loss. The server runs fine in 6.5 mode but it will not connect in 7.0?? Tonight I am going to try to reinstall SP1, if that does not work I am going to try to reinstall SQL 7.0. Any suggestions???

On a fresh installation of SQL Server 6.5, I have
opened the EM and registered the server but am unable
to connect. I get the error of 'A connection could not
be established to [ServerName]- [DB-Library] Unable
to connect: SQL Server is unavailable or does not exist.
General Network Error. Check your documentation.'
I've tried connecting with all different DB-Lib settings
to no avail. Ultimately, I want to use TCP/IP. I am,
however, able to connect to other SQL Server boxes from
this EM, just not the local server. I am able to stop
and start the services from Control Panel and from SQL
Service Manager.
Since I haven't been able to log into the local SQL Server,
I've registered the server in EM to log in with sa and a
blank password. I've already completely uninstalled SQL
and reinstalled it to see if that would help. It didn't.
Does anyone have any idea what the problem could be?
Thank you!

Hi,
I am running SQL 2000 on Windows 2000 Server. The clients are running different OS ranging from Win 98/NT/2000. Although i am able to connect to the local host, but whenever i try to connect over the network the following error pops up :
unable to connect to server <server name>
Server : Msg 11, Level 16, State 1
[Microsoft][ODBC SQL Server Driver][TCP/IP Socket]General network error. Check your network documentation.
I checked up the event long on the server and found the following entry:
Event Type: Warning
Event Source: MSSQL$NETSDK
Event Category: (8)
Event ID: 19011
Date: 1/20/2003
Time: 2:12:32 PM
User: N/A
Computer: <computer name>
Description:
The description for Event ID ( 19011 ) in Source ( MSSQL$NETSDK ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event:
(SpnRegister) : Error 1355.
May i further clarify that this error started today n till last week end (saturday, i am
stationed in India) there was no problem and the users were able to connect to the server
without any problem. My network engineer feels that its an sql problem and has nothing to do with network related issues.
i would appreciate if anybody could help me out. thanking in advance

From my Win98SE box with MDAC 2.6sp1, I can't connect to SQL (win2k, sql2k).
I've tried everything I know but nothing works.
I always get the following error:
Unable to connect to server 192.168.1.2
ODBC: Msg 0, Level 16, State 1
[Microsoft][ODBC Sql Server Driver] Timeout Expired
some additional info...
- both computers are in a workgroup, not in a domain.
- this is a home network and they're connected via a Linksys cable modem router
- another box on this same lan can connect to sql just fine, although it's
running win2k.
- all boxes have identical DSN, Subnet...settings
- I also installed Jet4.0sp1 just in case, but that didn't help either
- I'm primarily trying to connect via TCP, although I have tried Named Pipes
as well
- i can ping both boxes from each other just fine
- odbc ping fails
MDAC has worked beautifully for me for the last several years. Did MS
change something recently...or is there another problem?
Thanks, Andre

Hello. I am very new to SQL Server. I've tried to look through other posts on the forum but did not find the solution I needed. Please help.
I have SQL Server running on Machine1 which I am able to connect to. What I want to do is connect to this server through a Machine2 that is on my network.
Both Machines run on WindowXP Professional
On the server of Machine1, I have:
1. Under the security tab, I have created a New Login using SQL Server Authentication (general tab), checked all server roles (server roles tab) and checked to permit all databases (in the database access tab)
2. On the server, went to properties -> security tab and allowed for SQL Server and Windows authentication
On Machine2 when I try to register the server of Machine1 through the Register SQL Server Wizard, I am able to see the server. However, when I use the newly created Login Name and password (from step 1 of above). I get a Login Failed for user message. When I try to connect to the server through Query Analyzer I also get an unable to connect to server message (Server: Msg 18456, Level 16, State1)
What else do I need to configure to make it work?
Thank you!

If you place an image of your server on a rebuilt server, rename it andchange the SID. You get an error message “UNABLE TO CONNECT” when youuse the SQL Query analyzer on a desktop computer to connect to theserver (hosting the image). If you add the server (hosting the image)to the Windows2000 server domain/active server and restart the server(hosting the image), you get the following error message: "YOUR SQLSERVER INSTALLATION IS EITHER CORRUPT OR HAS BEEN TAMPERED WITH (UNKNOWNPACKAGE ID). PLEASE RERUN SETUP."Wouldn't you think changing the name, the sid and adding it to a domainwould be enough to access it. I even created a new ODBC connection.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Connections through a server alias, IP address, or any other alternate

There is the only local instance of the server on local computer and 'SERVER1' is actual name.

Is it possible to change the collation of your instance?
As far as I know it is not possible to change the collation once SQL Server has been installed.
When I said that SQL needs to be reinstalled at work the guys sent me this link: [URL]....
I ran it exactly like that but the collation didn't change.
I have also restarted the services but the collation is still the same.
Am I running this code wrong or am I right about not being able to change the collation after installation?

We are in the process of migrating our databases from one pair of Servers running SQL Server 2000 using a Failover Cluster to another pair.
Unfortunately, we have some programs that are hard-coded to the existing instance and it will take time I don't have at this time to rewrite those programs.
Our old Clustered SQL Server is named SQLCluster and the new one is named SQLCluster2
We have backed up and restored the databases themselves, but cannot seem to rename the new SQL Server Cluster to SQLCluster.
Is there a way to do this?
'til later,
