Hi AllI suspect that there is a disconnection between Windows 2003 Server and SQL Server.Are there any tools to detect if my suspect ions are really or not?Thanks a lot

Alaaay, There are a bunch of tools that you can use to find if network connections are dropping. My favorite is Netmon 3, which you can get at the link below, but you will need a little networking expertise to read the data. http://www.microsoft.com/downloads/details.aspx?FamilyID=983b941d-06cb-4658-b7f6-3088333d062f&displaylang=en TCPView is also an option, it shows any active connections on the box, and shows when they drop. Here is that link http://technet.microsoft.com/en-us/sysinternals/bb897437.aspx These two will get you started, and if there is indeed a drop, the netmon network captures may also show you why it is dropping, or at least lead you to it. If get to this point and you do not have the expertise in house to review these, you can ping me at the contact info in my signature line.
