MSDE (SQL Server does not exist or access denied.)

Hi all,
I'm getting this error message when I try to connect my MSDE database from other machine using enterprise manager application. Both of the machines are WinXP SP2. I found some solution such as using 'SQLServer Network Utility' but didn't work out for me. I even can not connect my database on my computer using TCP/IP. When I connect with name, it worked fine. I already enable both TCP/IP and Named pipe protocol on the MSDE machine.
If someone has solution on that please let me know.

Thanks,
MyoDid you open the ports on the computers ?

http://www.sqlserver2005.de|||If you have SQL Server 2005 installed on the same box as the MSDE, you need make sure SQL Browser is running. Make sure the ports (UDP/1434 and your TCP Port) are open if firewall exists. Also try file sharing between machines and make it work, otherwise NP won't work. When you use cliconfg.exe, make TCP and NP are on the client protocol lists.|||
Yes,
There is also SQL 2000 and 2005Express running together with MSDE. I already changed the port no and try to connect it. But, still didn't work out. I tried at the other machine and it works. I don't know why it still doesn't work at this machine. May be I miss some configuration. I'll try again. Thanks for the message.

I have exactly the same issue. I have installed MSDE2000 on a PC with Windows XP Professional and SP2. I have tried everything to connect to another remote server and still get the same error message

I have added ports 135 and ports 445 to the firewall but again without much success. Does anyone out there have any ideas on how to get this working?

|||You will first have to determine the port that MSDE is using by starting the application Srvnetcn.exe naviagte to TCP and note that number down. After this you will have to create an exclude filter for the firewall for the application sqlservr.exe using this number and the 1434 UDP for incoming request. That should egt you started for SQL Server.

Hi Jens,

Many thanks for your prompt response. I have tried all your suggestions but still cannot gain access to a remote database. TCP/IP is running on port 1433, using Srvnetcn.exe to check, and I have added both the entries you have suggested to the firewall exclude lists. Any other ideas? Thanks in advance
