Hi,

SQL 2005 EE is installed on W2k3 box and firewall is off in this server.
From my client machine, my window account and that developer window account
all can login into this server with ODBC, sql client, telent to 1433 or VS
connection. But, this developer can't login to SQL server from him machine
with any appliction. He is in the same domain as server and my machine. I
don't know what's the reason to cause this issue now.

Please advise. Thank you.

What is the exact error message and error number he gets
when he tries to log into SQL Server?

We only enable Shared Memory and TCP/IP protocal in server side. And, those
are the error they are getting.

Again, this developer is able to login by using my machine with his WIN
account.

After I enable Named Pipes in server. This developer is able to connect to
server on his machine by using Named Pipe.

Firewall is off in the server, so I can't think of the issue for TCP
connection on developer's machine.

Please advise. Thank you.

Sue,

The developer's client protocol order is TCP and NP. We didn't enable Named
Pipe in server at the beginning, that's why the first message is NP message
due to client will try to connect in the protocol order in the client. As I
menetioned, after I turn on Named Pipes in server, user's machine is able to
connect to server. But, the issue our developers had is that they couldn't
connect with TCP protocol from their machine. (I can connect by TCP protocol
from my machine. The developer login to my machine and his win account can
connect to the server as well). His machine is able to connect to our SQL
2000 with TCP protocol, but just can't connect to 2005 with TCP protocol. I
was thinging is firewall in server to caused this issue, but firewall didn't
enable in the server at all. So, I don't know what cause the issue.

Please advise.

When you get symptoms like this where it only affects the
user on a particular PC then you need to look at that PC.
You'd probably start by testing basic connectivity to the
server from the PC: Can the user ping the server by name,
can the user ping the server by IP, what network related
issues are found in the Event logs on the PC, can the user
connect to the server using sqlcmd, etc. Also, have you
tried logging in from that users PC?
If you find that the issue is comes up only with Management
Studio, have the user increase the connect timeout in SSMS:
When logging on, click on the options button in the Connect
to Server window and increase the connection timeout to
something greater than the 15 second default.
It would also be worth checking the users MDAC installation
using the component checker. You can download this from:
http://msdn2.microsoft.com/en-us/data/aa937730.aspx
You may also want to look at applying the latest SQL Server
service pack to the client on that PC having problems.

Sue,

Thank you again. Definitely, we already checked the network connect from
those developers machine. The connection issue happens to all related
developers. The developers were able to ping the server by name and IP from
their machine. But, the issue only happened on connecting to SQL 2005 with
TCP protocol. We tested through ODBC (with TCP/IP), osql, telnet to 1433
port, VS, but all connection were failed.

One developer already reinstall SQL 2005 client, but the problem is still
resisted. Will ask them to update to sp2 and go from there.
