When getting problems having an IP address assigned to one Windows machine but not another one, you start to check the one that is not getting it. Thinking it’s machine specific. However, when you find that particular version of Windows doesn’t get an IP address, you start to think of the DHCP server. I was running into the following situation:
\nClient with CISCO router 1800 series, another router 3500 series, switch 3500 series, and a call manager with IP telephone. The 1800 router was running the DHCP for computers, on separate VLAN. For some reason all windows VISTA computers doesn\u2019t acquire an IP address from that router.
\nAfter running a network sniffing tool, I found the request\/response going just fine, so the machine should have an IP. In fact, the DHCP server already assigned that IP in the table for the MAC address and set a lease time for it. Okay, what\u2019s wrong then? Checking the event log of VISTA found the following information:<\/p>\n
Log Name:\u00a0\u00a0\u00a0\u00a0\u00a0 System This wasn\u2019t clear enough, so back to the sniffing tool, I found one of the options passed along with the IP address (003 router) was passing two values, 192.168.xx.x and 255.255.255.0 and when checking the router DHCP configuration, found this: <\/p>\n","protected":false},"excerpt":{"rendered":" When getting problems having an IP address assigned to one Windows machine but not another one, you start to check the one that is not getting it.

\nMy guess that the CISCO guy who configured this missed the command syntax thinking he\/she should add a subnet mask to it, which for some reason doesn\u2019t affect any OS except the VISTA!!!
\nI tried my Linux version, and other XP systems in the office and all were running just fine with that ignoring the bad parameter!<\/p>\n
