I have updated the server recently (only those recommended security update from the windows server), after installation i had to restart the windows server, however after restarting the server, all the port are closed and I have no access with RDP (no access to sql server database, no access to tfs ...) . currently i can access to the server only over the ssl and i have access only to the cmd consul on the server. can any body help?(the server is in the ISP and it is a dedicated server).
Cause:
installation first kb2667402 then the Sp 1 update
effect:
No RDP available
Windows blocks users right and give no right to start the services
e.x
The TFS Service uses TFSSERVICE USER, but win2008r2 block this user and say this user is not exist!
what we have done:
uninstall the kb2667402
after Uninstalling the kb2667402, i have exported the installed update and proved that the updated has been successfully removed.
delete and copy the old version of the rdpcorekmts.dll in system32
reconfiguration of the RDP and add a new port and rule for firewall
reset the firewall and add the new rule (we made a back up)
add the Teamviewer portable version with a fix password, but we cannot access to the TV, "Authentication rejected"
Installed RAdmin--> no access: the user name or password is wrong!
try to connect with Computer management from my pc to the server and get the error: RPC Sever is Unavailable
I have stop the firewall and had access from my pc Event Viewer to remote server and could follow the errors on the server.

I am facing a problem that when i try to configure my TFS it show me the following Error Message
Error
TF255049: A connection cannot be made to the server that is running SQL Server. Verify that you have entered the correct name for the server, including the instance name, that the server you are attempting to connect to is online, and that you have the required permissions to connect. If you are attempting to connect to the remote SQL Server instance, then verify that it is configured to allow remote connections, that TCP/IP protocol is both enabled and configured to use port 1433 (default), and that Windows Firewall does not block this port.
Check whether the SQL version is supported by the TFS version: https://www.visualstudio.com/en-us/docs/setup-admin/requirements#sql-server
Check the permission of the account that you use, and make sure it belongs to SysAdmin Server Role.
As #Daniel mentioned in comment, follow the troubleshooting steps provided in the error message, and check this blog to see whether it is helpful: https://elhajj.wordpress.com/2013/02/25/workaround-error-tf255049-punching-a-hole-through-windows-firewall/
I was running an upgrade from TFS 2018 to Azure DevOps 2020.
After the server restart, the Azure DevOps Server Configuration wizard opened.
I was logged in as the local machine administrator and got this error (TF255049: A connection cannot be made to the server that is running SQL Server...) when trying to connect to my SQL Server machine (to chose the configuration database).
I logged in as Network Administrator, started the wizard again and the SQL connection worked.
To restart the Azure DevOps Configuration Wizard again...
Open the Azure DevOps Administration Console and choose Configure Installed Features to open the Server Configuration Wizard...
After installing the Directory Services Role and configuring and promoting the server to a domain controller the wizard automatically reboots my server.
After the reboot, I can no longer log in to the server as before (via RDP). What happened? This is a virtual server, so destroying it and starting over is an option, but after trying that 3 times how do I avoid this problem in the first place?
And another question is - can I install Active Directory without rebooting automatically?
can you ping ? what is the ping out put looks firewall is blocking or allow connections only from computers running remote desktop with NLA is enabled.
Why don't you install team viewer and setup unattended access and see what happening.
I have been trying to run debugging within SQl server management studio and for some reason the debugger has just stopped working.
This is the message I get:
Unable to start the Transact-SQL debugger, could not connect to the
database engine instance 'server-sql'. Make sure you have enabled the
debugging firewall exceptions and are using a login that is a member
of the sysadmin fixed server role. The RPC server is unavailable.
Before this I get two messages, one requesting firewall permissions and the next says 'usage' with some text that makes little sense.
I have looked at the other similar answers on there for the same message which suggest adding the login as a sysadmin but that is already set. I also tried adding sysadmin to another account but that also didn't work.
In the end I was able to start it by right clicking and selecting run as administrator.
I encountered this issue while connected to SQL using a SQL Server Authenticated user. Once I tried using a Windows Authenticated user I was able to debug without issue. That user must also be assigned the sysadmin role.
This happened to me and I could not find the resolution anywhere. My firewall is disabled so I knew that couldn't be the issue.
According to Microsoft: Configure firewall rules before running the TSQL Debugger:
The server needs to communicate back to the client via RPC. The
account under which SQL Server service is running should have
authenticate permissions to the client.
We had a group policy that was preventing this:
Deny access to this computer from the network (Local account, Guests)
In order to resolve the issue, I had to add the SQL Server service account to the local group "Remote Desktop Users" on my desktop. Hope this helps someone else resolve this frustrating issue.
I try with the following steps, but it did not work (maybe because I'm on a PC in a office and I don't have control of the firewall). But you can try the following.
Check the users role:
IF IS_SRVROLEMEMBER ('sysadmin') = 1
print 'Current user''s login is a member of the sysadmin role'
Follow these instructions:
configure the transact-SQL Debugger
Run SQL Server Management Standard Edition 64 bits (with SQL Server Account)
In my case, I received this error message:
Unable to start the Transact-SQL debugger, could not connect to the computer "local".
I end up close the existing connection, then reconnect to my local SQL server using IP 127.0.0.1 and it works.
What helped me, was from here:
SQL Server Management Studio must be running under a Windows account that is a member of the sysadmin fixed server roll.
The Database Engine Query Editor window must be connected by using
either a Windows Authentication or SQL Server Authentication login
that is a member of the sysadmin fixed server role.
So, I've added sysadmin role to my windows account and run ssms as administrator. Debugger started working normally.
In addition to above works, what make our 2 computers remote debug able, was running: (right click on Window's Start button)
System--> Advanced System Properties-->Computer Name-->Click on Network ID... button
and running that wizard to join workgroup on both computers.
I found this solution by looking at my Windows' Event Viewer and looking for a solution to errors with NetBT Source, that is related to workgroup and computer Name.
Update: after some days, it stop working again.
I had the same problem and double checked al recommended settings. At some point I disabled the firewall on the database server and it worked like a charm. By enabling and checking the Firewall log I noticed this entry:
2019-10-31 16:07:50 DROP TCP 192.168.xxx.xxx 192.168.xxx.xxx 65231 61214 52 S 56576751 0 8192 - - - RECEIVE
When I allowed TCP port 61214 (Inbound rule) and switched the firewall back on, it worked. I don't know why this port is needed, maybe some here on SO?
Anyway, maybe the firewall log can be of help too.
Struggled through many hours and got the answer
You can do the configuration through this doc

(1) 2 settings need to done on the remote server where Sql server is installed
(2) 1 setting at client computer (i.e) our computer
Has anyone accomplished pushing files to a BOE server using SSIS? I am trying to develop a SQL Server 2008 SSIS package that will push report (Excel) files to our Business Objects Enterprise (BO XI 3.1) server. Via a Script Task, I am using the Business Objects .NET SDK components to authenticate and connect to the BOE Server.
I have a copy of the package deployed to a local instance of SQL Server 2008 running on my Windows XP desktop. The package executes successfully (via a SQL Agent Job) and delivers the file to the designated location on the BOE server.
When I deploy the package to our development SQL server (SQL Server 2008 on Windows Server 2008 64-bit) and attempt to execute the package via a SQL Agent job, I receive the error message "File Repository Server Input is down" when the script task attempts to "Commit" the file to the BOE server. The package is able to open a session with the BOE Server, create a new info object, but fails on the infoStore.Commit command.
I have another SSIS package that executes successfully from our development SQL server - it communicates with the BOE server and searches for user sessions. It does not communicate with the Input File Repository - that seems to be the key distinction.
I have found limited information related to this error that indicates firewalls and ports between the SQL Server and BOE server may be the cause. I have reviewed the BOE Administrator's Guide to no avail (most likely due to my lack of understanding related to firewalls and ports). Both servers are within the same subnet and neither server has the firewall turned on. The ports for the BOE CMS servers and the Input/Output File Repository servers have been set to static port ids. Our network guy indicates there should be nothing preventing communication between the servers based on firewall or port settings.
Any help would be greatly appreciated!
Have you tried all the usual 'run as 32 bit' solutions? I guess yuor SDK is a 32 bit one, not a 64 bit one.
http://www.bidn.com/blogs/ShawnHarrison/ssis/2362/ssis-basics-running-a-package-in-32-bit-mode
However the fact the the SDK works for different services implies that it runs OK in 64 bit. So if you want to troubleshoot ports, I found this link http://scn.sap.com/thread/2027785 which indicates that the BOE ports are 6400 to 6411. To check that a given port is open, you go to a DOS prompt and type
TELNET hostname port
So if your BOE server is BOESERVER then you'd try this:
TELNET BOESERVER 6400
to test port 6400. You should get a black screen to indicate it's connected.
However, again, the fact that you seem to be able to connect and operate but not commit implies there is not a port problem as you can connect, just can't commit.
Are there any logs in the BOE side to give you a better idea of the issue?
A resolution to this issue has been identified and verified. The Windows AD account used by the proxy the SQL Agent job uses to execute the SSIS package did not have sufficient privileges on the network. Our DBA gave the account local Windows administrator privileges on the SQL server and this resolved the "File Repository Server Input is down" error I was receiving.
Thanks to those who responded and gave me other ideas to investigate.
I'm trying to connect to a remote SQL Server 2005 db from a .NET Windows service running in Vista Home Premium x64. I can access the remote db from a console app with no problem. I can connect to a local db from the Windows service with no problem. I was able to connect from a service from XP with no problem. There's no firewall or anti-virus running. How do I configure this service to be able to connect to the remote db?
I've tried to connect by running the Windows service as a local admin account, LocalSystem, LocalService, and NetworkService.
The connection string:
Data source=SERVER_NAME;Initial Catalog=DB_NAME;Integrated Security=True;
The 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
MORE INFO:
I have also tried to connect using SQL Server authentication with no success:
Data Source=SERVER_NAME;User ID=USER_ID;Password=PWD;Initial Catalog=DB_NAME
This connection string works from the console app too.
MORE INFO:
I ran Process Monitor for the Windows Service and the console app. The Windows service showed \SERVER_NAME\pipe\sql\query was ACCESS DENIED but the console app showed SUCCESS when reading/writing files to \SERVER_NAME\pipe\sql\query.
Good Lord! Why all the gibberish and complex responses on this site. Create a User Account
Either local or Domain and set the service to use that account. Then go into your SQL Server and Add you new account to the Database and set permissions. Voila!
Oh yeah, dont plague yourself with SQL Authentication. Integrated Security is much easier to maintain and without a password in your web.config your much safer.
1) open a command prompt. Type "ping SERVER_NAME". Does it respond? You may have a DNS or connectivity issue if this doesn't work.
2) "telnet SERVER_NAME 1443". Do you see anything or does it refuse your connection? This will definitively tell you whether or not someone is listening on the other end.
3) Go into SQL Server Management Studio. Right click Properties of your server. Select "Connections" from the left side. Is "Allow Remote Connections" checked?
4) Since you're running using network service/system, you will need to make sure you have a login configured on your server for the machine account DOMAIN\CLIENTSYSTEMNAME$. Note the $ sign. This is your machine account, and this will be the user that SQL Server will see.
