Hi,

I have 2 instances of SQL Server running on one machine (One 2K -default- and one 2K5), I have no problem connecting from a PC on LAN to the 2K5 instance, but when I try to connect to the 2K instance, it fails (it gives me an error: "Named Pipes Provider, error 40 - could not open a connection to the SQL Server"). I allow the remote connections on the properties page of the 2K.

So I ran out of choices, plz help me.

Thanks

just to get an idea can you show your connection strings to both instances?

Well finally I have to reinstall both instances, I don't know what happened but that solve my problem...
