If you have these problems after the connecting to SQLServer check these

• Check your Service Manager for runnig.
• Do you used of Data Source=NET101 in ConnectionString? (NET101 is my computer name)
• Do you used of SERVER=localhost in ConnectionString?
• Test IP for connection 127.0.0.1
• Run Enterprise Manager > (local)(WindowsNT) > (RightClick)Properties > Security > (select) SQL Server and Windows

- احتمالا Service Manager رو بالا نیاوردید.
- ConnectionString تون مشکل داره. مثلا برای کامپیوتری با نام NET101 این رو بد نیست بذارید. Data Source=NET101
- فکر کنم با افزودن SERVER=localhost به فیلد ConnectionString کامپوننت SqlConnection حله (البته برای کاربرهای خونگی)
- به جای نام کامپیوتر (اگه تو شبکه هم هست) بهتره که از IP استفاده کنید مثل 127.0.0.1
- گرچه برای من این جوری دستکاری تو Enterprise Manager حل شد :
Run Enterprise Manager>(local)(WindowsNT)>(RightClick)Properties>Security>(select) SQL Server and Windows
- افزودن USER ی به نام ASPNET اگه تو لیست user های Enterprise Manager هست بد نیست گرچه من userی به نام IIS... رو هم اضافه کردم ولی همون اولی کافیه که اضافه کنید و به لیست user های table دیتابیستون اضافش کنید و بهش هر دسترسی که می خواد بدین تا کارتون بگذره ;-)
