Fixed IP - No network

Dear ZyanWu,

First of all. Thank you very much for your help. Much appreciated.

Just a reminder. When I change from dynamic IP to static IP that is ALL I do.
No changes in router, network, firewall, etc settings.

When Win7 PC has 192.168.0.60 /24, everything works (file sharing, internet access, ping - all both ways)

As the DHCP range starts with 192.168.0.60 that is what I get when dynamic IP is choosen. When I use 192.168.0.60 as a FIXED IP no network but internet.

When Win7 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.

FIXED IP set. Can not see shares, filesharing not working, Internet access OK.

Basic network map looks like the picture below.

Yes. However don't know about god's gift! If I manage to solve this problem we might install and use Win7 on all our PC's

I know I can circumvent the problem as you describe. However I am still puzzeled by the behaviour of Windows 7 on this item.
Using a dynamic preferred! IP and set it to fixed just doesn't work! How strange is that?

The WinXP PC's or the Mac has no reserved IP's on the router and I can set any fixed IP both inside and outside the DHCP range and the full network is accessable by all work stations.

So no solution so far. I was hoping we could install Windows 7 on the other work stations but for the moment we will stick with WinXP and Mac. We need to have fixed IP's on all PC'c so that portforwarding can be applied without hickups.

If you set the IP manually, that code doesn't get set

Is this a bug in Windows 7?

As I said I can work around the problem, but had hoped it had worked as expected (WinXP and Mac)

Two wired PC's: 192.168.0.10 and 192.168.0.20
Third PC/Mac (Dual boot) 192.168.0.30
Two wireless PC's : 192.168.0.40 and 192.168.0.50
All fixed IP

LE: Wait a second. You're not trying to set the same IP address (192.168.0.20) for 2 different PCs, are you?
As I can see from your post, 192.168.0.20 already exists on your network on a WinXP PC

Of course it is not the same IP on any of the PC's. I think you getting confused.
I tried Win7 on a spare HDD and put it into the PC that is normally WinXP 192.168.0.20

One wired PC's WinXP: 192.168.0.10
Second wired PC WinXP/Win7 tryout 192.168.0.20
Third PC WinXP/Mac (Dual boot) 192.168.0.30
Two wireless PC's WinXP : 192.168.0.40 and 192.168.0.50
With fixed IP at WinXP/Mac configuration. Network/internet accessability.
With fixed IP at WinXP/Mac/Win7 configuration. Network accessability on WinXP/Mac part. No network access to Windows 7. Internet on all WinXP/Mac/Win7

It's not a bug, you just have to set it manually via registry. I don't know which one though.

Who knows about this setting?

Basically, if your wired lan and wireless lan are bridged then your network is fine and everything else's fine. I can't pinpoint the problem.

I've forwarded your question to Microsoft's Technet forums.

Still waiting for a solution to this problem, but it looks we are still stuck.

If this is the solution how come nobody comes forward?

ZyanWu....I was having a smiliar problem where a static IP wouldn't work on my Win 7 Pro machine. You're tip to enable NetBios fixed it.

Thank you.
