Windows 7: Fixed IP - No network

Fixed IP - No network

We have a network with a number of PC's. Until recently all PC's were WinXP and all set for fixed IP. All PC's accessable over the network and Internet connections working

Now we have installed Windows 7 on one of the PC's and only when this PC is set for dynamic IP everything works as before. As soon as the Windows 7 PC is set for a fixed IP this PC becomes inaccessable on the network, however the Internet connection works.
The router is D-Link DIR-615. Fixed IP's all outside routers DHCP range and firewall off.

Sharing is on and if there was anything wrong with these settings the PC's wouldn't be accessable with a dynamic IP ?

Sometimes when I change from dynamic to fixed IP I have connection, but as soon as I reboot I am back to square one.

Have checked this forum for solutions and it seems I am not the only with this problem, but fail to find a solution.

Greatful for suggestions

Had the same problem last year and got some help at this forum and thought I solved the problem. I could get it to work by switching from dynamic to static IP inside Windows 7, however after reboot and set to fixed IP no network,

Sorry can't help you as I am still looking for a permanent solution.

There must somebody at this forum that understand what is going on. Just be patient!

Try changing NetBios over TCP/IP settings. Set it from Default (using the settings from the DHCP server) to Enable.

Have tried that setting also, but problem remains

Enclosing I few screen shots that might give some clue to what is going on

Change the PC's IP address to 192.168.0.20 and then, from another PC, do the following:
Start -> Run and type in ping 192.168.1.20. Does it work? If not, tell me the error message.
Start -> Run and type in \\192.168.0.20\ . Does it work? If not, tell me the error message.

Also, make sure that you have the sharing settings below.

Thanks your help. Have followed your suggestions. See enclosed screen shots.

As you see I can ping the other computer 192.168.0.10 (WinXP) from the Windows 7 PC but can not ping the Windows 7 PC from the WinXP PC.

Regarding the file sharing settings they are as you suggested and are not changed when I go from a dynamic IP to a fixed one. Are there any settings I should change on the WinXP PC's? Maybe I am aiming at the wrong source of the the problem. However we have also a Mac on the network and all the WinXP PC's are accessable from the Mac with present WinXP settings

Are all the computers in your network connected to the same physical network device (router/switch)
or are there 2 or more routers between the XP computers and the Windows 7 computer?

After changing the IP address of your Windows 7 PC restart the router/switch and see if that helps (save any configuration on the router/switch if you have one).

And last but not least, if the above step doesn't work, your Network Administrator should be able to successfully troubleshoot the ping issue.

LE: At the moment, the fact that one PC can ping another one but the reverse doesn't work is mind-blowing (for me).

I might have figured it out.
On your Windows 7 PC:
Go to network and sharing center, click Change adapter settings (top left), press Alt (so you can access the menu), click Advanced, Advanced settings and move Local area connection 2 to the top of the list using the up button.

There is only one Router (D-Link DIR-615). Two wired and two wireless WinXP PC's, one wired Mac and one wired Windows 7

Have restarted the router plenty of times with both the dynamic and static IP settings.
No change in network accessability.

I am the Admin but I can not figure out what is going on!

Local area connection 2 already at the top.

What kind of sorcery is this?

OK. Let's see if I got this right so far:
  1. When Windows 7 PC has 192.168.0.60 /24, everything works (file sharing, internet access, ping - all both ways)
  2. When Windows 7 PC has 192.168.0.20 /24, file sharing only works one way (can see shares but cannot share), internet access, ping only from PC7 to any PC-XP but not from any PC-XP to PC7.
  3. Basic network map looks like the picture below.
I'll have to see some configurations from your router:
  • Any Access Control Lists (ALCs)
  • All device interfaces (including WAN)
  • All firewall rules
  • DHCP server pools/settings
  • Any port forwading/virtual servers/DMZ/NAT settings
  • ARP tables (one with Windows 7 as 192.168.0.60, one with Windows 7 as 192.168.0.20 and one with Windows 7 as 192.168.0.20 after a router restart)
  • Routing tables/static routes/routing protocols.
What I don't need: passwords. Strip/blur them out.
