Are you trying to connect wired or wireless?

 

[Martyn]

Have you checked proxy re-directs or hosts file?

 

[Frank]

What exactly do you mean when you say you're unable to get a connection?

Are the connections shown as disconnected in the network connections control panel?
Are they connected but they don't get a valid IP?
Do they get a valid IP, but just cannot browse the internet?


Also, what OS are you working with?

Definitely try this. Caught me off guard once in the early days, did all the really difficult-ish stuff first only to find the proxy had been set. A lot of tools don't reset the proxy as they assume that you have it set for work/college.

i'm trying both ways and still nothing. my test pc and other wireless/wired devices all connect with no problems.

maybe you should do a malware scan as they can mess around with network settings.

maybe you can post the output of ipconfig, open cmd prompt then type

ipconfig /all >c:\ipconfig.txt

then copy and paste in a reply!

The network connection are showing as connected for both wired/wireless.
They are both getting a valid IP but cannot browes the internet.

Also it's running a custom buid win XP Pro with SP3

Have you tried pinging out to anything?

Can you ping google.com? Does it at least resolve the IP address?

If not, can you ping any of the following IP addresses?

74.125.224.49
74.125.224.50
74.125.224.52
74.125.224.48
74.125.224.51

And as the other posters have mentioned, have you checked the proxy settings?

On ANY browser, or just IE?

 

[MobileTechie]

Some basic info would help here...

What does IP config say?

What happens when you ping a known public address?..or if you ping the default gateway...or loopback. How about if you set a static IP?

 

[mortaltech]

Yes i have tried to pingout and could not get out.

 

[mortaltech]

On ANY browser, or just IE?

Just IE. I have not installes any other browers.

 

[TheTech]

can you ping you router?

I did a malware scan first.

I know this sounds a little crazy, but go into the properties for the wired adapter and change the handshake to 10-full instead of auto and try again. I have found this to work especially with some linksys adapters.

I would also reset I.E in the menu.

It is worth a try.

 

[bagellad]

remove their antivirus.

 

[Hercomputers]

H-m-m....You mentioned that it's a custom build, correct? What anti-virus program is installed on there? Did you try disabling it? Could be in conflict with the Windows Firewall.

Also, did you check under Services to make sure that Network Connections, Network Location Awareness, Windows Firewall/Internet Connection Sharing and Wireless Zero Config are all set to Automatic and are turned on? You might have done this already but just in case you haven't-

It will prob wind up being something simple...lol

I can see that your default gateway is a class A network (10.x.x.x) which means the subnet mask should be 255.0.0.0,

Do you have subnetting on your network (i.e you have logicaly divided you network into two or more networks)

If not then that could be the reason why, you need to change the subnet mask from 255.255.255.0 to 255.0.0.0
