1/13 I need help fixing someone's Win2K box. Setup: Win2K box -> D-Link
router -> DSL modem. The Win2K box cannot obtain a DHCP address
(other computers can). So, I assign a static IP, and set the default
gateway and DNS server to be the D-Link router. After this, the Win2K
box can access web pages on the Internet as long as you specify the
web site IP address directly -- but DNS doesn't work. Computer used
to work fine, something about installing Windows updates hosed it
(they are on SP4). To summarize, the following is broken: can't
obtain DHCP-assigned IP address; when setting static IPs for host and
gateway/DNS, DNS doesn't work. Other computers on router are fine.
Thanks!
\_ Sounds like TCP/IP stack is broken. I've seen this happen
before. The only solution I've found to work reliably is
to unfortunately do a repair/reinstall off of the Win2k CD.
\_ Yeah, I kind of agree. A full re-install will be the last
option. I did try sticking in a new network card -- all drivers
installed fine, but same DNS/DHCP issues. I will try to Add/
Remove Windows components and try to take out networking. -op
\_ I assume you can't ping by name either? Did you go from SP3 to SP4?
I would look to see if the address that the machine used to have
isn't reserved on the router.
\_ We used 192.168.0.99 for static. That might be it, since
DHCP-assigned IPs are all .100 or higher. Don't know about
ping by name, but nslookup definitely didn't work for
http://www.yahoo.com or soda. I'll try everything suggested this
weekend.
\_ Are you connecting via wireless or with a wire? My
roomie "upgraded" to XP SP2 and now WEP security does
not work. I had to turn it off for wireless to work
for her.
\_ wired. fyi, encrypted wireless to the same router works
fine too. I use both that and 100BaseT when I'm over.
\_ As noted above, try "ping http://yahoo.com"; if you get no response, try
setting the DNS servers manually (I'm a fan of 206.13.28.12, myself)
If you're using IE, go to Connections->LAN and make sure the
"Automatically detect settings" box is unchecked. Also, can you
ping the router?
\_ I set the DNS server to 192.168.0.1 (the router), didn't work.
I'll try the IP you provided. pinging yahoo and soda's IP
address worked fine. I'll uncheck that box too.
\_ If you can ping Yahoo's IP address but not the name http://yahoo.com,
it's almost certainly a DNS issue. The quick fix is to set
the DNS server to the address above. Please post how this
works out, and good luck.
\_ Did he use Adaware recently? That can hose your registry where tcp
settings are. At least on XP. The fix I found for XP was WinSock
XP Fix. Don't know if there are easy win2k solutions.
\_ I'm going to try Ad-aware this weekend.
\_ Just to clarify, Ad-aware can damage your tcp stack and
produce exactly these symptoms.
\_ Wow, I didn't know that. Thanks.
\_ It can? I run AdAware and Spybot every month or so on my
Win2K machine, and I've never seen this happen. |
