windows VISTA not obtaining IP from router(DHCP)
DHCP is configured in the router and all the Windows XP and win98 systems are able to obtain IP from DHCP. but windows vista is unable to obtain IP from DHCP. We have tested the same Vista laptop with another Cisco 871 router and found working properly. We are experiencing the same problem with Cisco 1841 router also.

This issue occurs because of a difference in design between Windows Vista and Microsoft Windows XP Service Pack 2 (SP2). Specifically, in Windows XP SP2, the BROADCAST flag in DHCP discovery packets is set to 0 (disabled). In Windows Vista, the BROADCAST flag in DHCP discovery packets is not disabled. Therefore, some routers and some non-Microsoft DHCP servers can not process the DHCP discovery packets.

Hello Kevin,
thanks for this information.
We still have most users running Win XPs and only some testers of Win Vista.
We had already experienced problems in remote access field with Vista clients

Hello there. We are changing from XP to Vista now and we do not face many problems. Some problems were solved with SP1.
Have a nice day.
