  Can someone, maybe preferably from Microsoft, confirm a behavior that I'm noticing concerning the lesser accuracy of using TimeSpan and the Stopwatch object to time something in milliseconds versus using Environment.TickCount. Specifically, I'm noticing that in my Ping class that when I use Environment.TickCount to measure how long a host responds to my message, the result in milliseconds is accurate compared to the results when I use  ...Show All

  Any suggestions on how to replicate from AS/400 to SQL Server 2000 Data is stored on a AS/400, but applications use a SQL Server 2000 DB.

• SQL Server Pause/Continue distribution, content formatting or delivering.

  Notification Services get an event and create notification batch. Can I pause or stop process of notification delivery with (or without ) ability to continue I haven't tried it myself, but I can't see any reason why the standard retry logic wouldn't work.
