I'm having trouble doing so. I basically want to transfer files between two PCs and also share the internet connection from one. As you may know Windows XP supports FireWire Network Adapters. What I've done so far:
I've tried setting up "office or home network" without any significant result.
I've tried assigning IPs to the 1394 adapters on both PCs (different of-course) but for some reason I can only ping from PC2 to PC1 (and not the other way around).
I've also tried enabling internet sharing on the 1394 on PC1 (where I have internet connection).
Also for some reason running "ipconfig /all" doesn't show my 1394 connection ips (on both PCs). The same goes if I try looking at the 1394 Connection Status->Support tab. That is strange.
And if I try to repair the connection on PC1 it tells me that "TCP/IP is not enabled for this connection" but I've surely seen it enabled in properties. On the other hand on PC2 when I try the same - the error message is different: "failed to query tcp/ip settings of the connection".
And the strange thing I also mentioned in the comments is that removing/inserting the FireWire cable doesn't affect anything on the OS (no message that there was something connected, no nothing). But the 1394 connection status is always connected.
However as I mentioned earlier I was sure at a moment that PC1 was pingable from PC2 (no longer I think).
Any ideas?
PC1 as connected to internet was updated to its latest version shortly after installation. PC2 on the other hand have never been connected to the internet and so it have never been updated after its initial installation. Though both PCs have the same SP2 (which is the last one for the x64 version of XP).
I tried installing some of the "offline updates" from msdn to PC2 but without much success. However I think they are all secure and not functional patches.
My 1394 adapter seems to be recognized and working fine by what Windows shows. Its exact name is "VIA OHCI Compilant IEEE 1394 Host Controller". I bought the exact same controllers for both of my PCs. Though now I can't exactly tell their model but I will if it could be important.
EDIT: OK - I think I partially fixed the problem. Maybe it was the driver, maybe my 1394 controller - i don't know but I connected to PC2 using the card internal port (inside the box) and now both PCs are recognizable one another and so pingable. However right now I'm struggling to share my internet connection from PC1 to PC2.
