What DHCP server is running? Is it on the same IP subnet / vlan? Are there any log entries or either the client or the server to indicate attempts to communicate? Are these new machines or existing machines which suddently stopped getting an IP? -- There are 10 kinds of people in the world... those who understand binary and those who don't.

They are unable to obtain an IP from the DHCP server and the only solution is to set a static IP which of course works. I cannot understand why this is happening to just a few. The others work fine. Could this be due to some system corruption? I’ve tried resetting the TCP/IP network stack and the Winsock all to no avail. Has anyone encountered this issue before? Any help would be much appreciated. Thanks Pierre Pierre-Marie Camilleri B.Sc.
