    Having a strange problem which'll probly make sense to someone who knows more than me...

    I do a ping on a mail domain on one pc in the office and it pings an IP number which is the correct one

    I walk across the floor to another pc using the same internet connection and ping the same mail domain and it pings a different IP number, an old one

    Background: mail server was with a crowd in england, moved it over to an irish crowd yesterday - I understand that propogation has to occur, but don't know why two machines using same current connection show different ping results (different results happen with tracert as well)

    Is there a cache of some sort on the machine that is showing the old IP number and it'll be a while til this gets updated, or can I clear it myself?

    DNS lookups are cached locally on each machine so use "ipconfig /flushdns" to dump it and force a fresk lookup.

    thanks for tip - ipconfig /flushdns didn't work, did a bit of digging and found out a record was hard coded into my hosts file which i opened with "notepad %systemroot%\system32\drivers\etc\hosts" - deleted the reference in that and it works fine now
