Connectivity Issue - SQLServer Not Listening On Port 1433/ms-sql-s
Jul 23, 2005
Hi. I'm a SQL Server novice, so apologies if any of this sounds simple.
I am running Windows XP SP2, and have just installed SQLServer 2000. I
need another application to connect to SQLServer, and am specifying it
to do so via localhost:1433, but keep getting an error whenever I try
doing so saying it cannot connect to the database. A colleague of mine
has the exact same set up on his machine, and he can connect to SQL
Server fine. Running 'netstat -a' at the command line on his machine
reveals that the system is listening to port 1433/ms-sql-s. Running
netstat on my machine shows that the system is not listening to
1433/ms-sql-ms. I have checked in Network Config in SQLServer
Enterprise Manager, and TCP/IP is set to be using 1433.
To confirm this, my application can connect over the network to my
colleague's SQL Server. but he cannot connect over the network to mine.
So I'm pretty sure the issue is related to this 1433/ms-sql-s problem.
Does anyone know how to resolve this? Many thanks.
i setup a 2 node sql cluster but 1433 is not listening. I check sql configuration manager and entered 1433 for all ip addresses restarted services but still not 1433
I'm working on a school project on web and mobile applications, and had decided to use MS SQL Server for my backend database.
However, after I've installed MS SQL Server 2000, I ran a port scan and I couldn't find the server running on any ports (MySQL is running on my port 3306, but I guess it doesn't matter) Can something drop some hints on how to debug the problem?
I'm running on Athlon XP 2000+ w/ Windows XP Professional SP2
I have SQL Server in NT 4.0 which has two IP addresses. How to force the SQL Server to listen to specific IP address ? We can make client to listen to specific port & IP and let me know the way to configure SQL Server to listen only to specific port that will make to ensure that SQL Server can be communicated throught that specific port.
Your answer would be highly appreciated. regards, Nana
I have a named sql instance on SQL 2012. The issue is that the clients is having problem connecting to it when the firewall is on, this is not consistent. The connection is fine when I disabled the firewall. When I turned the Windows firewall back on, it will work for awhile and it fails. I checked the SQL configuration manager and saw that a dynamic port is assigned to the named instance. I did put that in the firewall rule and unblock it. I also put TCP 1433 and 1434 as well as the browser service port, TCPUDP 2382 and it still didn't work.What is the best way to determine what port does the named instance are listening?
24/7 Production Call Centre server running NT4.0 and SQL 6.5 with all the latest service packs.
SQL mail fails(with dull regularity) and the SQL server services stop.
When the SQL server Services are restarted an error message appears stating that Port 1433 is in use after which nobody can connect via TCP/IP. Obviously the port believes the previous SQL session is still running, and won't release the port to the "New Application requesting it".
On a unix system you can force a port reset so you don't need to shutdown and restart the box. Can you do this from either SQL or NT?
Any solutions would be greatly appreciated the DBA's are 100 Miles from the Servers, so restarts are reliant on other people!
Does anyone have an idea on why when using IP with port 1433 that on the SQL 2000 Server a bind failure happens on port 1433 and are not able to get to the SQL using IP but you can use Named Pipes.
So, I have 2 laptops, both with standalone SQL Server 2012 Management Studio.
laptop 1 can connect to my remote server on xxx.xxx.xxx.xxx,1433 laptop 2 cannot connect through management studio - but can connect directly from the development website on this machine.
I get error 18456, cannot connect to server and login failed for 'user'
Witam!Mam problem z polaczeniem sie z baza danych po TCP/IP przez port domyslny1433, nie mozna sie telnetowac ani nic z nim zrobic, poprostu niezyje. Portjest zamkniety i nijak nie moge go zmusic do jakiejkolwiek komunikacji nawetpo localhoscie. Skaner portów wykrywa go jako zamkniety. Czy wiecie moze jakten port otworzyc i zmusic go do komunikacji z baza danych? OS win2k3,MSSQL2000 Server.PozdrawiamHello!I have a problem with a TCP/IP connection to Data Base through the 1433port. I cannot telnet on this port even on localhost. My firewalls aredisabled but port scanner see the port as closed. Protocol TCP/IP on theMSSQL Server is enabled and it's not hidden, so I don't know what I shouldto do. My configurations: Win2k3 Server, MSSQL Server 2000Thx for answers.
Been having SQL Server 2000 running for some time now, but recently it stopped listening on TCP port 1433, the log reports its listening on shared memory, Named pipes and Rpc, but no sign of 127.0.0.1 port 1433 or any errors to say why it won't listen.
I've done a netstat -na and nothing else is listening on that port, tried restarting using the enterprise manager, gonna try restarting the entire Server when everyone has gone home, but I'm pretty sure its been restarted recently.
All the other archive logs going back a few days show its not listening.
Yes, I have used the Server network utility to make sure TCP/IP is enabled and set to 1433, even added a comma and 1434 to see if it will listen on multiple ports, no go.
I want to know how to check whether SQL Server 2000 can listen to port 1433 or not. If I run netstat -a, am I suppose to see port 1433 regardless of what service pack I have applied to SQL Server 2000?
for some reason i dont get any errors, but i believe that my server isnot running on port 1433. the tcpip protocol is selected in thenetwork configuration utility as well as name piper. the portselected is 1433. but when i telnet to 1433 i get the same errors as iwould if i telnet to a non existant port. i also tried nbstat with noluck. what else can i do? thanks
Does SQL mobile require port 1433 to be open for RDA? I was under the impression that all synching occured through port 80. But when 1433 is restricted a connection cannot be completed.
I may be missing something really simple. My understanding of tcp/ip networking concepts are not very solid.
I have installed MS server sql 7.0 and 2000 both on my PC. The default port i know is 1433. If sql 7.0 is already installed. Which port does sql 2000 listen on.
I've got SQL 2000 set up on a cluster running Windows 2000 Advanced Server (w/SP1). Setup for Failover Clustering appeared to succeed normally on both nodes.
The SQL 2000 server logs show:
2001-01-11 10:02:57.82 server SuperSocket Info: Bind failed on TCP port 1433. 2001-01-11 10:02:57.85 server SQL server listening on Shared Memory, Named Pipes. 2001-01-11 10:02:57.85 server SQL Server is ready for client connections
I've checked to see if something else is using port 1433 (unlikely) and don't see anything. The physical node that SQL 2000 is currently on has no other cluster resources assigned to it. Any ideas?
Version: SQL SERVER 2012 enterprise edition and SP2.
Due to one of the security reason, I have changed default port 1433 to another port number in configuration manger tools->protocols for MSSQLSERVER->TCP/IP --> IP ALL section mention another port number.
After restarted service, SQL SSMS able to connect server itself and new port number also LISTENING.
But SQL client SSMS not connected to one of the PC side after changing default port.
HiI have a question regarding the SQL Server(SQL Server 7) port 1433.Some body is trying to hack into our Windows 2000 server through port1433. Is there a way i can close this port? I tried using a toolcalled Ipsecpol.exe ( Internet Protocol Security Policies Tool). Butwhen we run netstat, it still looks like they are able to connect tothe server using port 1433. Has anyone come across this problem? Iwould appreciate it very much if somebody could send in anysuggestions regarding this.Thanks,Ann
I'm working on a completely virgin install of SQL Server 2k in Windows 2003. Just after install I check that the TCP/IP protocol is enabled under the server properties and then I try to Telnet into port 1433. On this one particular box I get back the following:
C:>telnet localhost 1433 Connecting to localhost...Could not open connection to the host, on port 1433: Connect failed.
For comparison I tested telnet on a couple other machines and I get back a blank window ready for my commands, as I'd expect.
I've checked the firewall settings and other IP Filtering settings to see if any of those were blocking traffic to 1433... nothing. I've triple checked the SQL Server settings for any "problems" and nothing jumps out at me.
We have 2 clustered SQL instances (2 physical servers in each cluster). Instance2 needs to be setup as a linked server on Instance1.
At this time port 1433 between them is not open. I am referring to the port on the network switch, not in the Windows Firewall (ports in Windows Firewall are already open).
Is opening the port between virtual IP-s sufficient? Or does port need to be open between all physical source/destination IP-s as well?
I have a new named instance (SQL Server 2005 x64 SP2 (Build 3159) Developer edition) setup with dynamic port selection. A default instance was also running on the server prior to the named instance setup.
SQL Server Browser service is running. Remote connections are configured on the named instance. But still remote clients can only connect when the port number is specified after the instance name (servernameinstancename,9999). Without the port number, "error 26 - Error locating Server/instance specified" is thrown.
Doesn't the SQL Server Browser service eliminate the need for clients to specify the port number? What am I missing?
I'm doing some vulnerability assessments of MS SQLServer installationsusing AppDetective.On doing the "discovery" proble (to find the instances), I find that Iget two "hits" -- port 1433 shows the MS SQALServer instance, but port1434 comes up with MS SQL Server Redirector.The online books seems to be a bit light on waht the use of this portis for.I thought that port 1433 was the port on which SQLServer listens forODBC connections.However, port 1434 seems to be used for the same purpose.Any additional information of a non-technical level (my manager needsto know this and he's not a DBA) is greatly appreciated.Thanks in advance!
I have an installation of SQL Server Express 2005 installed on a Windows 2003 server. Through the forums on the board I have been able to turn on and make sure that port 1433 and port 1434 are turned on and listening. However, both ports show that they are listening on IP address 0.0.0.0. and I need for port 1433 to either listen on the server's main IP address or at the very least on 127.0.0.1. I have set them to enabled in the Configuration manager but they still don't appear to be listening on either of those IP addresses. Could some one tell me if there's another configuration change I might need to make?
I am running SQL Server 2000 on windows XP pro. I have configured (enabled) TCP/IP protocol and left the default port 1433, but SQL server still does does not listen for client connections.
Can anyone tell me what might stop SQL server from listening???
With the server running, here is what I see (nothing on 1433...):

One of my production SQL Server 2000 systems is listening on TCP and Named Pipes, but not on Shared Memory.
This server has a lot of scheduled jobs that are internal to this box. I assume these jobs would benefit from using shared memory instead of TCP/IP, but I can't figure out why it doesn't use shared memory already and how to correct that.
