Please help 
Two PCs one runs windows XP home the other Windows XP Pro both servicepack 1, both properly registered and activated.
Both machines have add on firewire (PCI) adapters. ( Do not want to use these for PC to PC connection, too far)
The Pro machine has Ethernet adapter on board and the Home has a 10/100 Level one PCI Ethernet card.
Pro was manually configured with IP 192.168.0.1 and mask 255.255.255.0 and a member of workgroup "MSHOME"
Home was also manually configured with IP 192.168.0.18, mask 255.255.255.0 and also a member of workgroup "MSHOME"
now trouble begins.
They refuse to see each other >Network neighborhood> etc..
The Pro pings Home but when I try to ping the Pro from Home it times out. No way to map a shared drive from either machine using IPs (\\192.168.0.18\sharedc) where sharedc is the shared as name for the C drive of machine Home. It tells me that I do not have permissions and I should seee the administrator of " MSHOME" (the Home does not even ping so no point to try and map)
This thing has ruined my weekend and It has gotten me so mad I cannot think of what may be the problem.
I thank in advance anyone that tries to Help
Thanks
