SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified

I'm pretty sure this is a common question, but i still cant seem to find a solution even after a couple days of searching google. I checked my connection strings several times. The port number is 1433 and the database name is correct. In fact, I only get
this error when i'm trying to login with a username and password I made in the asp.net configuration (which works locally). I'm getting kinda desparate/ willing to try anything. Any ideas?

Hi,
It seems like this issue was more related to Microsoft Azure SQL Database, I will move this thread to Microsoft
Azure SQL DatabaseForum for a better help.
Thank you for your understanding.

Please!!!Some body help me solve this problem(except format my computer),i really really need your advice.

Hi huydaibang,
The older version SQL Server 2005 could be installed with SQL Server 2008 R2 side-by-side. It could not be the problem.
The reason that we get this error message is the client stack could not receive SSRP response UDP packet from SQL Browser.
Here are the steps:
1) Make sure your server name is correct, e.g., no typo on the name.
2) Make sure your instance name is correct and there is actually such an instance on your target machine.
3) Make sure the server machine is reachable, e.g, DNS can be resolve correctly, you are able to ping the server (not always true).
4) Make sure SQL Browser service is running on the server.
5) If firewall is enabled on the server, you need to put sqlbrowser.exe and/or UDP port 1434 into exception.

Intermitten error - SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified

Problem: I have a 2 WFE & 1 App server in my SharePoint 2013 Enterprise Edition SharePoint farm. My WFE 2 and App servers connect all the time to the SQL Server using a SQL alias. My WFE1 server work 80% of the
time. It is setup exactly like WFE2 except periodically 1 web app/site collection will stop working and throw the following error:
"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)"
When I log into WFE1 I can connect to SQL using the alias using a udl file and telnet to verify the SQL alias is connected.
Hypothesis/guess: It appears like WFE1 periodically looses networking but only for 1 specific site collection.
Any ideas are most welcome?

Hi Aries,
I can rule out SQL Server (AOAG) Always-on as the farm doesn't use it.
"max worker threads" is set to 512 with 4CPU's. Rule out.
From the log and looking at the breakdown of the SharePoint request, the request is hitting the WFE2 server which in turn is trying to connect to the content database. The connection string/instance is not available. In summary, I believe the
issue is WFE2 periodically cannot connect to the SQL instance. At the same time WFE1 is working so we know it isn't the SQL server. WFE1 & WFE 2 are on the same VLAN and both appear connected and can see the SQL database using a udl file.
WFE2 has other web applications that are working while the erring web site fails. An IIS reset fixes the issue and restarting the "App pool" for the offending IIS website also fixes the problem. This tells me the issue
is the IIS process. When it tries to connect to SQL /the content database it fails.
I already raised the ticket with MS , the engineer has been looking at it with me, we have tried to identify the issue and also looked at TCP Chimney offload being a possible issue. As my servers is Windows Server 2012, all the servers have the default
"TCP Chimney Offload" setting set to "disabled". WFE1, WFE2, APP1 and SQL have the same setting so this is not the issue. At least this has been ruled out.
http://support.microsoft.com/kb/951037
http://blogs.msdn.com/b/psssql/archive/2008/10/01/windows-scalable-networking-pack-possible-performance-and-concurrency-impacts-to-sql-server-workloads.aspx
I will keep posting about the problem, hopefully MS support can escalate and the root cause can be determined.
"The bottleneck is on the WFE2 server process trying to communicate with SQL. SQL is up and listening. Only 1 of the website/WebApplication on WFE fail for 15-20 minutes while the other websites are fine."

Lync SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified

Dear all,
I'm getting an error when I want to publish my Lync Topology. Thanks in advance.
error:
Error: 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)

Hi,
Would you please elaborate your Lync server environment?
Did the FE server and BE server on different subnets? If so, please try to relocate the SQL server in the same subnet as FE server and then check again.
Please also double check if the step of “Prepare first Standard Edition Server” ran succeed, if not please run again.

'Remote Insight Board Interface Error' - Rogger Server

HP monitoring software on the system has detected the following event only once for our Rogger Side B Server:
SNMP Trap: 9006
Date time: 09/22/2010 01:35:07 AM
Computer: CALROG02
Source: Server Agents
Type: Error
Category: (4)
Description:
A 'Remote Insight Board Interface Error' trap signifies that the
Compaq Remote Insight Board has detected a controller interface error.
Details:
None
Is this going to affect our services / Cisco application or it can be ignored, Since the system has detected only once.
Many thanks,
Srini

I can't think of any more obvious things that could be wrong. The best thing to try next is to set up a trace between the portal and the AWS using a tool like TCPTrace to see what the exact error coming back from the AWS is.
You should also probably open a ticket with support.

AnyConnect - loss of network interface error

I am getting the following error when connecting from a single computer.
"The VPN connection was terminated due to the loss of the network interface used
for the VPN connection."
The only reference I can find to this error currently is a person on this forum having the same issue with a VZ Air card (no resolution) and another in a Cisco tech doument that tells me to restart the device but that's it.
I have uninstalled and resinstalled through Add/Remove programs but not much else beyond that. I can see the VPN hitting the firewall but nothing beyond this. It appears as though the service doesn't have proper permissions and/or something is automatically shutting of/disabling the interface.
Thoughts?

Most people that have 4G loose the data network , it seems it is not to stable.

Error while server instance start up

We are using SunOne App Server 7.0 on Solaris 9.x.
While starting the server instance, we are encountering following problem
WARNING: CORE3283: stderr: sm_ftok failed calling stat: No such file or directory
WARNING: CORE3283: stderr: 8752: CSemCounter failed to get key with sm_ftok.
Startup process doesn't go ahead of this point. Please help

The message you see seem to indicate a problem while starting logging threads. You might want to check if you have some appserver processes running. If you do kill them and try to restart your appserver instance.
You can also check if you have log rotation set incorrectly or some third party logging enabled(i.e log4j) that might prevent appserver startup.

Network Interface problems on Mountain Lion Server

My Mac mini server has been migrated from 10.6.8 Server to 10.8.3 with Server 2.2.1.

I could see this too when in System Preferences, Network, that it was constantly renewing the lease of DHCP on the Ethernet interface. (The server gets its IP via DHCP from the router). This has worked well for years. I was even unable to edit a manual setting, until I disconnected the ethernet cable, because trying to edit the manual ip address was interrupted by the system changing. I have now set up a manual entry and the system is a lot more workable. The router has never given these problems and it even does not now give these problems on the client machines. Somehow, I suspect the server itself to be the culprit in that it tries to renew the lease constantly itself (lease time is 1440 minutes).
After some researching, I may have found the cuplrit. My Network settings have a Wifi device which is unconnected to a network. That was no problem previously. but I see a lot of configd entries i nthe logs:

I have set the network setting to manual, this seems to stabilize matters. I'm now going to test what happens if I go back to DHCP, but without the unconfigured devices

Back to DHCP for 20 minutes now. No more transitions and the system is stable. DHCP was not so much the problem, its seems, but the unconfigured WiFi interface was.
Hmm, if OS X Server tries to be smart about signals like a network change (I can understand that Apple sees that as a good thing), I'd better have a stable network setup. So, apart from deleting all the unused interfaces, I'm sticking to a manual IP for my server. One source less of instability problems.

Can't update software through app store, since Feb. Says no updates available. Error says server with specified hostname not available.

Can't update any software or apps through appstore. Updated Itunes after several months by download, install. Using my own Macbook on my network, never had this problem. Re-installed Mountain Lion. Removed file softwareupdate.plist from Library preferences. Repaired disks and permissions. Any ideas? seems like a small issue, but this is pretty serious going forward.

Please test after each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes. Keep in mind that no one here represents Apple or can help with customer-service issues.
Step 1
A purchased app can only be updated by signing in to the App Store with the same Apple ID that was originally used to buy it. There's no way around that limitation, which also applies to free apps. If you can't sign in with the buyer's ID, delete the app and reinstall it. You'll have to pay for it again, if applicable.
Step 2
From the App Store menu bar, select
Store ▹ View My Account
Enter your Apple ID password at the prompt. At the lower right corner of the window that opens, click the Reset button. Close the window.

I can't figure out why the named instance does not work but the other one does. Any help would be greatly appreciated!

Did you check with the ODBC test utility isql (it is installed by default when you install the unixODBC Driver manager) if your ODBC driver can connect at all to that named instance? I have some doubts that it will work either as there was a blog commented by a MS engineer:
Introducing the new Microsoft ODBC Drivers for SQL Server - Microsoft SQLNCli team blog - Site Home - MSDN Blogs
who states that named instance connections are not supported using that driver.

Hi Shitij,
Thanks for your reply.
The issue remains the same even after re-registering the service.
While Installing and registering the Service, the following error appears:
Error: Service not started.
While starting the service from SAP Management Console, the following error also appears:
Error:
Cannot connect to SAP Serviceon sapserver.
Web Service error : 20
Unknown error.
DCOM Interface error : 80040154
Class not registered.
Please guide me to resolve the issue.

I am new to JDev. Can someone please help me with this?

Use a supported JDK (1.6.something, not 1.7) is what the original poster didn't do.

DPM failing SQL backups due to error: "the SQL Server instance refused a connection to the protection agent. (ID 30172 Details: Internal error code: 0x80990F85)

I ran across this error starting on 6/4/2011 and have been unable to find the root of the problem. In our environment, we have a DPM 2010 server dedicated to backing up all our SQL envrionment (about 45 SQL Servers total). All of the SQL
environment is backing up fine except for a SQL Cluster Application. This particular SQL Instances is part of a 6 node failover cluster with 6 SQL Instances distributed amongst them. The other 5 SQL instances in the cluster are backing
up fine; only one instance is failing. The DPM Alerts section shows this error when attempting to do a SQL backup of one of the databases on this SQL instance:
Affected area: KEN-PROD-VDB001\POSREPL1\master
Occurred since: 6/11/2011 11:00:56 PM
Description: Recovery point creation jobs for SQL Server 2008 database KEN-PROD-VDB001\POSREPL1\master on SQL Server (POSREPL1) - Store Settings.ken-prod-cl004.aarons.aaronrents.com have been failing. The number of failed recovery point creation jobs =
4.
If the datasource protected is SharePoint, then click on the Error Details to view the list of databases for which recovery point creation failed. (ID 3114)
The DPM job failed for SQL Server 2008 database KEN-PROD-VDB001\POSREPL1\master on SQL Server (POSREPL1) - Store Settings.ken-prod-cl004.aarons.aaronrents.com because the SQL Server instance refused a connection to the protection agent. (ID 30172 Details:

More information
Recommended action: This can happen if the SQL Server process is overloaded, or running short of memory. Please ensure that you are able to successfully run transactions against the SQL database in question and then retry the failed job.

I have checked the cluster node this particular SQL instance is running on using Perfmon and the machine is nowhere near capacity on CPU, memory, network, or Disk I/O.  I have failed this SQL Application to another node in the cluster and
receive the same error (this other node has another clustered SQL application on it that is actively running as well as backing up fine). The only thing that I am aware of that has changed is that we installed SP2 for SQL 2008 about 2 weeks prior
to when the failures started to occur. However, we updated all six clustered SQL Instances at the same time and only this one is having this issue so I don't believe that caused the problem. We are running SQL 2008 SP2 (version 10.0.4000.0)
on all clustered instances along with DPM 2010 (version 3.0.7696.0) on this particular DPM server that has the issue.
One last thing, I have also noticed errors in the event log pertaining to the same SQL backups that are failing (but the time stamps are not concurrent with each backup attempt):

Any help would be greatly appreciated!

Don't know if this helps or not, but I also noticed another peculiar issue that is derived from this problem. If I go to "Modify protection group", then expand the cluster, then expand all six nodes in the cluster, five of them show "All SQL Servers"
and allow me to expand the SQL Instance and show all databases; the one that is having a problem backing up, when I expand the node, doesn't even show that SQL exists on the node, when in fact, it does.
I would also like to add that the databases on this node that will not backup are running fine. They run hundreds of transactions daily so we know SQL itself is OK. Even though it is a busy SQL Server, there is plenty of available resources as
the SQL buffer and memory counters show the node is not under durress.
