I am having trouble with the dns address on several computers that are on our network. They keep changing at will. If I do an ipconfig /renew it reverts back to the two addresses that are ment to be on the computers. I have found the computer that was causing the IP Spoof issue and removed it from the network. The Malformed issue is from the computers that have changed their ip addresses. I will post a hijack this log from the server along with the sonicwall log if anyone can be of help I would greatly apprectiate it. Thanks in advance.
