DNS Cache needing frequent flushing
Posted on 2011-03-09
We have a SBS 2003 Domain with approx 55 computers. I am finding that the workstations are requiring me to run 'ipconfig /flushdns' frequently in order to allow for connection to a small SQL based time and billing software database. General slowness often is associated as well. Every few days or so, users will lose the ability to connect to the database through the software and their general network access becomes somewhat sluggish. When this happens, i simply run 'ipconfig /flushdns' from the command prompt and all returns to normal. I have gone through the DNS server configuration on the server, and everyhing seems ok.
Anyone have any idea what I might be missing that would clear this up on an ongoing basis?
