Windows 7 vs Win XP

[busster]

Have an interesting problem.

A customer is upgrading to Windows 7. They are currently plugging their WinXP PC into their 9608 phone without a problem. If they plug a Window 7 PC into the same phone/port, they get a network error, "unknown network".

Customer is using static IP addresses on their PC's.

Plug the same Win7 PC directly into the wall, without changing anything, no problem. Plug the phone back in, plug a WinXP PC in, no problem. Plug the Win7 PC in, no go.

Same IP / subnet / gateway IP addresses.

Ideas?

The firewall software on the Win7 pc has been disabled, and it works when you by-pass the 9608 phone and plug directly into the wall jack.

I did not check the nic card port speed, but I assume that it would auto-negotiate the speed, (realize I just said assume).

Have you tried a different ip phone same type that you know that works in another location , swap them round and see if the fault follows the phone or pc , this could be firmware related but I cant see it, maybe even just clearing the phone back to default and starting from fresh .

Both PCs (XP and 7) are using static IPs? Are they the same IP or different IPs in the same subnet/VLAN? Do you have any products on your network that review connected equipment before allowing them on the network? Is there a possible GPO that is treating your Win7 and WinXP differently for the network connections?
