Workaround To Connect To SQL Server When Ports Blocked?
Jan 11, 2006
My SQL Server is a shared account at MaximumASP.com a client just deployed my .NET application on GoDaddy.com and they have all there ports blocked and my app cannot connect to the SQL Server. Using "Network Library =dbmssocn" in the connection string did not help and GoDaddy will not help. MY QUESTION IS: how can I get my .NET app to connect to the SQL Server? web service? This is the first time I have run into this problem. There seems like there has to be some way. THANKS IN ADVANCE!

Does anyone know what ports are required to be open (non-NT). We are placing the SQL-Server behind a UNIX firewall, and want to minimize the ports open.

If I am doing an Index Server query from SQL, such as:SELECTQ.*FROMOPENQUERY(FTIndexPM, ''SELECT path, characterization, rank, hitcountFROM SCOPE('DEEP TRAVERSAL OF .....can anyone tell me which TCP/UDP ports will be used between the SQLServer and the Index server if the Index Server is on another machine?I'm doing the query from SQL so that I can join the results with atable in the database and am not interested in doing the Index queryfrom the app server. I haven't been able to find any info on the netfor which firewall ports are used for this.

I have an existing 2012 default SQL Express. It's set up on a VPS managed by a third party. I have an administrator account on this 2012 Windows server. I'm not much of a sysadmin or a DBA but I get around. ;)
I've installed a new NAMED instance on this VPS and can not connect to it with client tools (SSMS). If I remote in, I can connect this way.
What steps might a seasoned DBA expect to make when getting a new named instance ready for the world.
Assign a port? Check the port?
Open the firewall for the port?
Will this new named instance listen on a different port than the previously installed SQL Express instance?

I have changed SQL Server from default port to another port number. All appears fine. If SQL Server is restarted it is all fine, however, when the server is restarted SQL Server fails to start. If you then log into the server and manually start the services they start just fine. So, it appears that something blocks the port or uses the port upon server startup for a few seconds. The AV folks say that they are not blocking ports and that it AV service actually starts 15 seconds after the SQL start failure.So, the question becomes is how can I track down what is blocking or using that port?
This is Win2012/SQL2014 CU3
Server failed to listen on xxxxx::xxxxxxxxxx <ipv6> xxxxx. Error: 0x2741. To proceed, notify your system administrator.
Server failed to listen on fe80::5efe:10.255.196.25%18 <ipv6> 14001. Error: 0x2741. To proceed, notify your system administrator.
TDSSNIClient initialization failed with error 0x2741, status code 0x1. Reason: Initialization failed with an infrastructure error. Check for previous errors. The requested address is not valid in its context.
Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log. SQL Server could not spawn FRunCommunicationsManager thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.

I have a question about blocked processes. My manager wants to know how you can know the following when a blocked process is encountered.
The job, program and the statement that is causing the blocking. I have figured out how to determine the database involved but not a lot else. Such as in the blocked process report there is a waitresource field. How to you decipher it?
The report also tells you the client application, but in this case it just states the Micro focus Net Express as the client, not the job or program that is running.
I have an inputbuf listed but it just shows the database id, and the object id. And I am not sure how to locate the object id in this case, I am guessing sys.objects, but I do not seem to find that one.
I have read many things on MSN about the blocked process report, but it does not seem to go into great detail.
I seem to have all the pieces, but do not exactly know how to quickly tie them all together.
Any help would be appreciated.
Thanks,
Kathy

I've inherited 6 sql server 2000 boxes. I've upgrade 3 with no trouble. now I have one that gives the message :
"your upgrade is blocked because of cross-language compatibility rules.
For more information about cross-language support, see the version..."
all servers are 2003, sp2. All SQL is Enterprise edition, default language is "english". even the collation order is
the same. why the cross language message? Any help would be good else I'll be forced to rebuild the DB and load application again. ugly!!

Had some big problems with my SQL Server 2008 R2 SP1 during the last maintenance running on Windows Server 2008 R2 Enterprise ( upgraded from Standard). I'm getting the following error,
"SQL Server blocked access to procedure 'dbo.sp_sqlagent_has_server_access' of component 'Agent XPs' because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Agent XPs' by using sp_configure. For more information about enabling 'Agent XPs', see "Surface Area Configuration" in SQL Server Books Online."
I did a google search and found others with the problem but the resolution isn't working for me. I ran the following commands, heck I ran them multiple times. No errors come back running these commands. But the same error keeps happening, I even restart the service and then the server again.
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Agent XPs', 1;
GO
RECONFIGURE
GO
The msdb got too big for the disk it was on. I had maintenance plans to clear out the all of histories but I didn't think of the mail items. When I finally saw this problem I tried clearing them out using the stored procedures only with it finally failing because the transaction log got full. Since we didn't have a lot of jobs scheduled I decided to just recreate the msdb. So I scheduled a maintenance window, download SQL Server Service Pack 3.
my steps are as follows:
->diff backup of msdb
->stopped the service and started it again with: NET START MSSQLSERVER /T3608
->detached msdb with: SQLCMD -E -SP-SRVR-SQL-01 -dmaster -Q"EXEC sp_detach_db msdb"
->moved it off the drive
->restarted the service without any startup flags
->recreated msdb with: SQLCMD -E -SP-SRVR-SQL-01 -i"D:Microsoft SQL ->ServerMSSQL10_50.MSSQLSERVERMSSQLInstallinstmsdb.sql" -o"D:Microsoft SQL ServerMSSQL10_50.MSSQLSERVERMSSQLInstallinstmsdb62715.out"
I looked at the log file and there were no actual error messages so I applied service pack 3 and restarted server after it installed, was actually prompted to restart. In my tests I was never prompted to restart the server.Now I never started the agent service after recreating the msdb database since I knew it wasn't on the same version. I just went directly to the latest SP. Our applications are running fine but now I cant do scheduled backups.

What ports does SQLMail use to access MS Exchange Server?? We have SQL 7 running on a seperate non-trusted domain(within the same DMZ) from where Exchange Server exists. The only trust we want between the 2 domains is the SQLMail functionality for the DBA's and Administrators to use. I am aware that MS Exchange uses 110 port for POP3 and port 25 for SMTP. Does this apply to SQLMail as well? Thanks in advance for your support.

I'll have about 5 db's from an instance(server1instance1) mirrored to another server(server2/instance1). Do all of these db's have to have endpoints configured with different ports? I hope I'm clear on my question. Do I have to create a different endpoint for every db or can use the same endpoint? Thank you

Hopefully someone can answer this as I am yet to find any definitive information.
User access reports by default on port 80.
Report Manager and Report Viewer are on machine A. Catalog database is on SQL Server machine B along with the database being reported on.
What ports are required to be open between machine A and machine B? Does it use standard SQL port 1433, are there any other ports used?
Thanks

Hi,
Using SQL Configuration Manager, i have set my local instance to use TCP Dynamic Ports by setting the value under IPAll to be 0 (the value TCP Port is blank). However, when i start up the server this value gets set to a specific port. ie Before startup TCP Dynamic Ports = 0, After startup TCP Dynamic Ports = 2832. This value persists throughout SQL Server restarts.
Is this behaviour correct as I would have expected this value to stay 0?
I am using SQL Standard, SP2. SQL Browser is running.
Thanks in advance!

The very simplified version of my problem is that these
Select DISTINCT Cast(KWID as NUMERIC)
FROM OV_MID
Select DISTINCT Convert(Numeric,KWID)
FROM OV_MID
should work, but don't because KWID is a varchar and somewhere in there is something that won't convert.
I get this error:
Server: Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.
I would love to find out which rows are causing the error, but more importantly I would like to have a Null value where the conversion doesn't work and the numeric values where it does work.
I have already deleted all obvious non-numeric characters, but I believe there are some line terminators being read as carriage returns in this table. :confused:
Any workaround or way to determine which rows have KWID that cannot be converted to numeric would be most appreciated.
Thanks!

Hi All,I have read about deadlocks here on Google and I was surprised to readthat an update and a select on the same table could get into adeadlock because of the table's index. The update and the selectaccess the index in opposite orders, thereby causing the deadlock.This sounds to me as a bug in SQL Server!My question is: Could you avoid this by reading the table with a'select * from X(updlock)' before updating it? I mean: Would thisresult in the update transaction setting a lock on the index rowsbefore accessing the data rows?Merry Christmas!/Fredrik Möller

I have two instances of SQl 2005 running on a server. One I'm going to allow outside remote access to. But I don't want to do it on the default port. though I have it allowing remote and that seems to be working. I can seem to find where to change the default listening port.
and I scimmed the help and topics I saw. But didn't see one relevant to this question.

When a ReportViewer control is used to access a report on a remote SQL Server database, on what ports does the communcation occur? Does the control communicate on on the SQL Server ports of 1433 and 1434 or does it communcate as a web service on port 80 (or 443 for HTPPS)?

The function "DATEPART(wk, [valid_date])" appears to have the following bug:
DATEPART(wk, date) returns week 53 for the following dates (checked years 2000, 2001, 2002):
year 2000: 12-24-2000 through 12-30-2000 inclusive
year 2001: 12-30-2000 through 12-31-2001 inclusive
year 2002: 12-29-2002 through 12-31-2002 inclusive
DATEPART(wk, date) returns week 54 for the following dates:
year 2000: 12-31-2000
SQL2000 SP1.
Are there any known workarounds/fixes/patches for this (other than just hand-coding the function?)
Thanks!

I'm converting crystal reports to SSRS reports right now and came across this function that I'm not familiar with.
It's a formula field in crystal that has this formula:
quote:whileprintingrecords;
NumberVar RTCurrent;
NumberVar RT31to60;
NumberVar RT61to90;
NumberVar RT91to120;
NumberVar RTOver120;
if {@AgedDays} < 31 then RTCurrent := RTCurrent + {@BalanceDue} else
if ({@AgedDays} > 30 and {@AgedDays} < 61) then RT31to60 := RT31to60 + {@BalanceDue} else
if ({@AgedDays} > 60 and {@AgedDays} < 91) then RT61to90 := RT61to90 + {@BalanceDue} else
if ({@AgedDays} > 90 and {@AgedDays} < 121) then RT91to120 := RT91to120 + {@BalanceDue} else
if {@AgedDays} > 120 then RTOver120 := RTOver120 + {@BalanceDue}
@Aged days is just an integer, but that shouldn't matter for this thread.
Is there just a While loop equivalent for this in SSRS?

At some point in time, when I release my code from developemnt to production, somebody will onvoke the SQL Script containg my certificates and symettric keys based on my master key. Unfortunately this seems a bit of a weekness as my SQL SCRIPT contains the CREATE MASTER KEY ENCRYPTION BY PASSWORD stement which has the password itself in clear. (script gets invoked from a command line in a batch script which is all under documeny mangement control). Obviously I would not like my password to be be in clear anywhere - i.e. not in document control nor viewable from whoever invokes the script. What is best pracrice to adopt on this? - encrypt the script file?
Thanks

I have written a UDF into which I pass a table name, field name, value of the field, whether alpha characters are valid, whether numerics are valid, and a string of alphanumerics that are valid. I return back a string with all invalid characters removed. Unfortunately when I use this on names and addresses in an 12000 row table, it takes forever to run.

Hi,
Any insights to this issue would be great.
Following is my problem statement. I have write around 20Batch programs and in each batch i have atleast 7-8 data validations. If any of the data validation fails then i have to perform a log operation and exit.
Now I have each of my data validation as a Script Task (Control Flow) which inturn would call my SP and set the "Status" variable accordingly
I have written a "OnVariableValueChanged" Event with Raise Change Event for "Status" variable set to "True" Now in this event i check if Status = False, if it is false then i perform the log operation and throw a new DTSException to abort the control flow execution. The event gets fired but it continues to process the next control step(but i wanted it stop there). I could have acheived this by setting a precendence constraint (Status = True) for all of my control flow task but i feel the other approach to be very elegant.
Any suggestions to make this work??
Thanks & Regards

I am trying to group on the number of distict field values. Basically:
=Ceiling(CountDistinct(Fields!ClientID.Value, Nothing)/10)
So for every 10 different clients, I get a group. I get an error with the above function saying aggregates are not allowed in a grouping expression. I tried creating a text box with the running value:
=RunningValue(Fields!ClientID.Value,CountDistinct,Nothing)
The value of the text box is correct, but I can't reference that text box in the grouping function. It says the textbox is undefined.
Any suggestions for a workaraound?

Hi Everyone,
I am new to the forum and would like to have a question answered. I want to to install Sql Server Express with advanced services but also want to have IIS installed as well. My question is, how do I install IIS without it opening Port 45? When I installed it, it would not let me finish installation without letting it act as a server. Is there any work around to solve this problem that any of you have managed to use?

I would like to use SSL on SQL Server 2005.
With SSL, is all traffic from the client to the database on port 443 ? Or are other ports needed ?
With Windows Certificate Management Snap-in, a request for a certificate assumes that there is a local Certificate Authority. I don't have one and it is my understanding that I should buy a third party certificate to avoid a man in the middle attack. With IIS there is a certificate request process. Is there something similar I should use with SQL ?
Thank you.

When multiple instances of SQL 2005 are installed on a cluster or standalone server, is it best to have each instance configured to listen on a different port or will one port for all do? We don't use port 1433 and the port we do use is blocked at the firewall. I'd like to standardize on one port for all instances but I'm not sure of the ramifications. Any thoughts?
Thanks.
