No internet access when PDC is down

Hi all -

this is more of a discussion point than a question - whenever I restart my Primary Domain Controller, I (and all my users) loose internet access. I am just wondering why this is when I have a BDC that also has DHCP and DNS on it...

Thanks for the info,
K

it sounds like you have your clients pointed to the PDC for DNS & when it is down no resolution is taking place. Or it could also work as a proxy server??

I have no proxy set up, and DNS is set up through DHCP, not statically

If you need end users to be able to web browse while the PDC is down the you need to add the BDC as a second DNS in the DHCP options, you could also add the router IP as well

I echo what karllangston said...

if you loose Internet while the PDC is rebooted then the client arte pointed to the PDC somehow. One test would be try to PING yahoo.com while the PDC is up. Write down the IP address then you a ping -a while the PDC is rebooting

Hm. I posted this question because every time that I had restarted my PDC, I lost internet connection. I've since made a few changed in my network (my BDC died and I replaced it) and I just rebooted my PDC and didn't loose network connectivity! I guess that it was probably an error in my previous BDC. Thanks guys!

Be sure in DHCP that you have server options configured for DNS with BDC entry, and that DNS is running on BDC
