SQL Server connection error

Hi,

I have 30 workstations connecting to a SQL server, with the following connection string.

driver={SQL Server};server=" & <servername> & ";uid=sa;pwd=password;database=SAMS

Some of the workstations get the following error:

Run-time error  '-2147467259[80004005][Microsoft][ODBC SQL Server Driver][Named Pipes]Access Denied

This is after the workstation worked fine for a couple of weeks, but after getting the error for the first time, it will not connect to the server again.

Any ideas are welcome, this is quite urgent.

have you tried restarting the server? Are all connections being closed once you are done accessing the server?

try the following:
Provider=SQLOLEDB.1;Password=password;Persist Security Info=True;User ID=sa;Initial Catalog=SAMS;Data Source=IPADDRESS

What version of SQL Server are you using and what service pack ?

On your server check the number of concurrent users allowed to access your SQL server. It's under Tools SQL Server Properties.

Also make sure your Workstations all have the same versions of the NT service packs and MDAC.

Go to client configuration and add the server if it doesn't exist.
check whether it connects and then try connecting.
Are you using TCP/IP protocol ? Give the IP address of the server while adding the server.
This should work.

Couple of days ago i face the same problem the main reason of the problem is that your proxy is not working properly.

The second cause is that you tcp/ip is not configure properly. Configure it from every client by giving them a proper port no.

I have enough client connections available, as all 30 workstations could access the database 2 days ago.

The server has been restarted, always the first thing I do when I get funny errors.

And I am closing all the connections once done accessing data.

Running SQL Server 7.0 SP1
Workstations all running 98

He's using named pipes not TCP/IP this will work across the network also and apparently has been working for him.

This sounds like it's on an internal LAN so a proxy probably doesn't even come into it.

Also he will need to configure the Client Network utility to use TCP/IP, Named Pipes is the default.

Don't think this is the problem.

I'm not rejecting your answer outright, but I don't have instant access to the network in question as it is a 5 hour drive from my offices.

I've instructed the person there to install remote control software so that I can try your proposed solution.

In the meantime I would like other people to be able to add comments, so in order to unlock the question I have to reject the answer for now.

Please insert answers as comments, it can also be selected as an aswer, but does not lock the thread.

Regards
Barend

No correct answers here, it was actually the user using a user id and password that did not have rights on the server, asked the user to check this first, but she's not that bright so I got the wrong answer from her.

Anyway, I'm closing all my questions and would like to award points here.  First on to respond gets the points.
