I am working on a Vista Home Premium system that is fully patched and yesterday it would not longer get an IP Address from the cable modem. I did some checking with my laptop and I was able to get an IP Address from the modem. I dropped a different NIC in to the system and same thing – no IP Address from the Modem – just the APIPA address.
I decided to take the system with me for additional tests, I can have it get a valid IP Address when I attach it to my network but when I try to go direct to my cable modem – same thing APIPA adresss.
I used MSCONFIG to turn off all non MS service and stop all the startup stuff – still no IP when attached directly to the cable modem.
Any ideas beside throwing a router in the connection sequence?
