Why am I getting an error message, "No process on the other end of the pipe?"

Can not log into the SQL (Server 2008 R2) instance anymore using SQL authentication. When I attempt to login using SQL authentication with a user that has login permissions, I get the attached error message.  I enabled "named pipes," the suggested solution and did not fix the issue.

Any other ideas? Thanks

there can be several things affecting.. you can try the following

1. Login as Administartor
2. Right click on the Instance name - Server Properties
3. Security page
4. Set the Server Authentication - 'SQL Server and Windows Authentication mode'
5. Restart the SQL Service


1. Login as an Administrator into the SqL Server
2. Expand Security/ Logins folder
3. Right Click on the particular user and go to properties
4. Click Status Permission: Granted Login : Enabled


1. Log into an administrative account that has access to both the machine and sql server 2008 database
2. Open up SQL Server Management studio with "Windows Authentication"
3. Click on the security folder
4. Click on "logins"
5. Then click on the account that is not working
6. Answer - Make sure there is a database within the "Database Default"  specified "for example, the admin account to master

The first 2 solutions did not work.  Not clear what you mean by #6 in the 3rd option.
Under Default database:  =  master

Should another database be chosen in the dropdown instead of master?  Thanks

Looks like a lot of good information. I tried some of the suggestions but nothing seems to make it possible to login to the SQL Instance using SQL authentication.

Windows authentication works fine. We are running a clinical website which requires SQL authenticated login.
Is tcp\ip enabled or not? If not, please do it.
And then check the server is ready to do remote access. Most probably it should be as with windows authentication you are already able to connect, but just wanted to re-assure.
