Hi,I have a Database server, which is running on a Windows 2008 Server 64bit also Service Pack 2 instaled. Database server is a SQL Server 2005 64Bit.I have also an exchanger configured on this server which is comunicating on port 1408 by GPRS with equipments like PDAs for a Sales Force Automation application to grab informations from database's aplication.The server is conected to a Linksys Switch, this Linksys is conected to a CISCO switch, and the Cisco Switch is conected to a Linux Server, then the gateway is a CISCO router.The phenomenon is that the aplications stops to comunicate with the PDAs after 19 days.Aslo Internet Explorer doesn't seem to comunicate.

Hi,Thanks for the post.I am wondering if this database's aplication can communicate with the client machines. And what do mean that Internet Explorer does not communicate? Would you describe it in more detail? Is there any event error on the problematic server?Thanks,Miles

Hi, The database application doesn't communicate anymore with client machines such as PDAs after 19 days and a few hours.In Internet Explorer if I want to open www.google.com a receive a error of connection such as I don't have access to Internet.I checked de event error on the server but Windows Server doesn't warn anything, a warning or an error in logs.Thanks,Adis
