2 computers hooked up on wireless local lan. (Home) , I have the host puter on wireless d-link with my dad's in another house. I received an error last weekend that my wndws media player had a PROBLEM and needed to empty the DNS Cache ?  I searched DNS Cache and found many, and started deleting files , I received  a couple don't delete warnings and SKIPPED those deletions. I had no problem connecting online after that but noticed my media player still won't work-online, it will play local music and stuff but won't play mpegs, and video.... Yesterday while at work , I tried to send an email to the 2nd computer in my dad's house and received this  delivery status notification....to my email ACCOUNT at work......

unlovedwarriorThe DNS cache has nothing to do with Media Player of any sort other than allowing thos e programs to access info over the web.
The 2 things are not related.
In future when you feel the need to flush..... open a command prompt window and type "ipconfig /flushdns"

patio.    8-)patio is there a way to see how full your dns cache is?thanks  both of you for the  HELP
