We upgraded our accounting software, which is running on SQL 2008 R2. Each user has a client that connects for entering their time each day. I have a handful of users who are crashing after about 10 minutes. Tech support for this product is saying saying it's losing it's connection to the SQL server. At first I thought it was only my wireless users, in which case I found out the company does't support wireless connections (which is terrible for my laptop users), but I've still got some wired desktops having issues. They don't ever lose connection to my document management SQL server, nor the old accounting SQL server. Nothing network wise has changed and I'm having a hard time believing that this many users are having a "connectivity" issue with only this one application. All that to ask this "How do I test SQL connectivity and where would it be timing out at?" These are a mix of WinXP and Win7 workations. Any thoughts would be greatly appreciated.
