i am using a leased line connection …and through a d-link router my 3 servers r connected and while all r working fine suddenly i had seen that the from oracle server i cant ping to any other computer and vice versa i repaired the connection.. disable it .remove both end and put nothing works. .finally i had removed the utp cable and plug into the spare network card on it and change the settings to that card then the connections r found to be ok..then the next day i change back to the previous card it was working fine…why it happened so..
