Hi everyone, I'm having a bit of trouble with my home network. My local DNS server (dnsmasq) is assigning an entry for each host, but Windows 7 seems to be unable to use them. For example: C:\>nslookup xbox Server: DD-WRT Address: 192.168.1.1 Name: xbox Address: 192.168.1.115 C:\>ping xbox Ping request could not find host xbox. Please check the name and try again. It's clear that the server is returning the proper response if it's queried, it's just that Windows isn't sending queries. Here's a copy of my ipconfig /all: Windows IP Configuration Host Name . . . . . . . . . . . . : MyPC Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Wireless LAN adapter Wireless Network Connection 3: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Linksys WMP600N Wireless-N PCI Adapter with Dual-Band Physical Address. . . . . . . . . : 00-25-9C-07-98-F1 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IPv6 Address. . . . . . . . . . . : 2001:470:1f07:13b:225:9cff:fe07:98f1(Preferred) Link-local IPv6 Address . . . . . : fe80::225:9cff:fe07:98f1%26(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.1.149(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : Sunday, October 30, 2011 8:03:31 AM Lease Expires . . . . . . . . . . : Monday, December 11, 2147 4:51:11 AM Default Gateway . . . . . . . . . : fe80::2ff:ffff:fe00:1%26 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DNS Servers . . . . . . . . . . . : 192.168.1.1 NetBIOS over Tcpip. . . . . . . . : Enabled As you can see, Windows is configured to use the correct DNS server, it's just not sending the queries for some reason. Other non-Windows machines on the network can both resolve and connect to hosts by name. I've searched the forum and found issues where people want unqualified names to be expanded, but not a case like mine where the unqualified names should work as-is. This isn't the end of the world, but any help would be greatly appreciated. Thanks! Edited for additional info: This problem occurs with all applications, not just ping.

As you don't use DNS prefixes, uncheck the "Append primary and connection specific DNS suffixes" under "Advanced TCP/IP settings" / "DNS tab" of the properties of TCP/IPv4 of your "Wireless LAN adapter Wireless Network Connection 3" . Wolfgang Unfortunately, that option is a radio button and not a checkbox; the only alternative is to append suffixes from the list below, and an error message is generated if the box is closed with that list empty. There doesn't seem to be a "Resolve unqualified names as-is" setting.

Hi, Please use Network Monitor to capture the package for the nslookup and Ping individually, then upload the log to Skydrive and post the link here.

Thanks for the link; I'll run that as soon as I get home today and post the results.

I can't remember where I came across this solution, but I do believe it will "resolve" your problem. It worked for me with the exact same scenario. The answer provided by Wolfgang is nearly there. Under the DNS tab of the properties of TCP/IPv4 you need to change the radio button to "Append these DNS Suffixes in order" AND THEN click "Add" and for the suffix just enter a period. "." (without the quotes of course). "Works for me." :) Good luck.

Worked for me also. thanks.

Worked for me also. thanks.

What worked for me: Under the "Append primary and connection specific DNS suffixes" I UNchecked the box for "Append parent suffixes of the primary DNS suffix". So...now to find out how to set this with a GPO. Thanks for the tips.
