my domain server last night got messed up after a power failure. originally, the dhcp service quit working, but in the process of fixing that, i seem to have broken the ability to resolve dns names. everything else works ok and i can ping out to IP addresses. i tried to manually reinstall tcp/ip, but that didnt help. does anyone have any ideas?
oh, by the way, the dns server works ok too.

BTW, 'like your description of your computer with the "circus lights"...
yea, i meant the dhcp server. sry. i wrote that on 1 hour of sleep. this particular server runs dhcp, wins, dns, ad, and several other things. all those server services are running and working properly, but the outbound dns requests to my router (which does a dns pass through thing), arent getting through. for example if i do a nslookup on google's ip, it times out after 2 seconds saying it connected to 192.168.xxx.1. it works on all the other computers tho. ipconfig /flushdns didnt fix it.
nope. that too is set right. ive checked all of the obvious configuration related stuff. im thinking its something in the deepest darkest depths of windows that is screwing it up. i tried to run a tcp/ip fix tool that i saw was recommended in a couple other forums, and i think that may be what broke it. dns resolution was working while the dhcp server was down.
The DC is the DHCP server and the DNS server for your internal network right?
Do you have forwarding setup so that requests that the DNS server can't resolve (like web addresses) it goes out and asks an internet DNS server?
If I read you right...you can't type "ping computerxyz" and have it resolve, where computerxyz resides on your internal network.
all the internal stuff works. just cant do external dns resolution on the dc. yes, forwarding was enabled. but i also has the router set as the secondary dns server on all the client computers.
i think i may be experiencing a hardware failure tho. im going to run dft and ill post back with the results. some other problems with ad popped up today. missing file related stuff.
I had that happen once. It's good to know ISP's in MI are as bad as they are here.
Please, visit THIS thread for important information re: power protection.
i used to have an apc 1500 backup running everything. was great till it blew. then i got a warranty replacement, then a month after the warranty expired, it blew again. yes, i had allot of load on it, but by no means was it maxed out. i really need to get a new one. i saved the battery tho, and i plan on adding it to the new one via the extra battery port on the back.
You can also put a quality (high joule rating) power surge protector between the UPS and the power source (e.g. wall outlet) to protect the UPS. Just be sure to monitor the LED on the power surge protector and replace it as soon as it's failed. (Power surge protectors are designed to sacrifice themselves between the power event and your equipment. Eventually, depending upon the number and severity of the hits, they will fail and have to be replaced.)
APC has a 600VA (for a 10A line) voltage regulator you might be interested in.
They also have Data Line protection equipment as well as Residential Surge Protection installed at the junction box. (I don't know if you're set up is in a residence or a commercial building.)
You might want to contact APC. Tell them your situation and get their recommendations. That'd probably be the best way to go.
If you're looking to save $ but still protect your equipment, you could install a $30 APC BACKUPS UPS on ea. computer/monitor combination. I don't know how good an idea that is. Again, you might want to discuss this w/ an APC rep. who could help you find the least expensive solution. In the end, you don't have to go w/ APC, of course. Just use the information you get from them and their UPS selector when choosing a power protection solution for your set up.
