Hi,

I got this error when i click menu item.

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

In that menu, previous menus are working. This is the last menu. If i select this the corresponding form is not open.

If anybody know solution to this please help me.

Thanks

Dear Friend,

This may be due to LAN problem. try to ping the server of SQL from your machine whether the packets are received or not.
