Dell Optiplex 3010 Internet Issue

[jshix]

Hi forum members,

I have a Dell Optiplex 3010 desktop running Windows 7 Pro, 32Bit in my office. This morning I was unable to access the internet though I was able to print and access other network drives. I did a troubleshoot and found out that networks status changed from work to public. Error on network icon is "Unidentified network, no internet access". I did ping our router but timmed out. I can ping other servers & PC's on the same network but cannot ping the router or default gateway. I did the following

1. ipconfig /release or renew-did not work
2. ipconfig /registerdns/flushdns - did not work
3. Disabled network card or enabled it - did not work
4. Changed IP address from DHCP to Static - did not work
5. Updated, uninstalled, repaired network driver - did not work
6.Changed Speed/Duplex settings to 100Mbps, 1TB or Auto - did not work
7. Removed other networking services - did not work
8. IPReset All - did not work
9. Removed all Antivirus softwares -did not work
10. Disabled firewall

I am not sure about this issue. If anyone can assist me here. I will really appreciate him or her. I have been working on this issue for almost a day now.

Thanks in advance

Hello jshix and Welcome to the Forums, try some of the fixes in this article first. There are a couple you have not tried yet: Windows 7 DNS server not responding
If still not resolved, we can try other things. post back results please.

Thanks Yard Dog, I have tried all the threads however same issue still exists. I really need help here..

 

[Yard Dog]

Try running this to see if you have a file corrupted : option 2 : http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html?ltr=S

 

[jshix]

Hi Yard Dog, I have run the command SFC /scannow without errors. Refer log file attached. Anymore ideas

 

[Yard Dog]

K.. great.. restart computer. Retry internet access.. post back if unable please.

 

[jshix]

Hi Yard Dog,

I just restarted the computer but same issue still exists..I cannot access internet.

 

[Yard Dog]

Most odd.. but.. still things to try. Go to start button, then go to Control Panel. then Internet options, open that. Open the connections tab. press Lan Settings. , In that window. make sure auto detect is checked. and do not use proxy is showing as.. do not use proxy . press ok.. then retry to access internet..
Post back please.

 

[jshix]

Done that. It is already set to "Automatically Detect Settings". Still no internet access

 

[jshix]

Also I cannot ping the router/default gateway and DNS servers.... It is timing out..

 

[Yard Dog]

Well.. we need to try a restore pt.. do a restore to a day before this issue.. Lets see if that works.. Don't quit on this..we will get it.. you have clean registry files per SFC . so.. just a matter of sorting this out..
Post back when restore done and an attempt is made to access internet .

 

[jshix]

Hi Yard Dog,
I have restored to an earlier date however same issue still exists..Still cannot access internet.

Thanks for your time..

 

[Yard Dog]

Well.. this is only computer in the office unable to access the internet . so.. files are clean. you have done alot of fixes to put the issue to rest.. and still unable to access Internet from the one computer. Have you tried to make a new connection by using the program in windows ? start button. control panel, network and sharing center. press connect to a network ? Try that. please

 

[jshix]

Yes I can connect and ping to other computers on the network. I can print & access shared drives. It is internet access only. Other computers on same network can access internet.

 

[Yard Dog]

Start button. type device manager in search.. go to Device Manager.. and check network drivers

Run IPCONFIG from command prompt. Do it on computer that CAN access internet and the one that CANNOT. Post both results

4. Changed IP address from DHCP to Static - did not work
6.Changed Speed/Duplex settings to 100Mbps, 1TB or Auto - did not work

Set to DHCP as it should be. Put the Speed/Duplex setting back to what it was a few days ago (it was working).

Maybe you already answered it (I just joined this thread)... can other home computers ping the router?

Computer is connected WIRED to router, I assume?

 

[Kaktussoft]

I can ping other servers & PC's on the same network but cannot ping the router or default gateway.

internet Router and default gateway have the same ip-address I assume?! The computer's default gateway SHOULD be the ip address of the router which it is directly connect to. Normally you have this on your pc if using home routers:

Ip address: 192.168.x.y (y is different for each machine. DHCP gives you a free address)
subnet mask: 255.255.255.0

In windows terms it means: 192.168.x.* are all attached to same router, no further routing needed. Requests to other ip addresses are delivered to "default gateway", he knows how to route it further.

default gateway: 192.168.x.z (z is most likely 1 or 254, but can be anything in range 1 to 254).
DNS-server: can be router's ip address (it simply forwards it to ISP). Or it can be ISP's DNS servers.

All above settings are done automatically when using DHCP.

Now waiting for IPCONFIG output

I asked you:
Run IPCONFIG from command prompt. Do it on computer that CAN access internet and the one that CANNOT. Post both results

So post from a working computer as well

 

[Kaktussoft]

relevant data from not working machine:

DHCP Enabled. . . . . . . . . . . : Yes
IPv4 Address. . . . . . . . . . . : 10.46.60.46(Preferred) =>looks quite normal. Other home computers have ip address 10.46.60.* ? For example 10.46.60.51 ?
Subnet Mask . . . . . . . . . . . : 255.255.255.0 =>looks quite normal. Same subnet mask on working machine?
Default Gateway . . . . . . . . . : 10.46.60.1 =>looks quite normal. Same IP on working machine?
DHCP Server . . . . . . . . . . . : 10.46.60.1 =>same as default gateway... nice. It can find DHCP server
DNS Servers . . . . . . . . . . . : 208.67.222.222 , 208.67.220.220 =>that's opendns. It's working on other machines. It's not a dns issue anyway!
