Thanks Jim ... IP addresses are clean. Only one Mac so far has TCP
installed, and we can shut it down and use the exact same IPs in a Win95
client with no problem. Also, we're not subnetting, just assigning static
IPs from a pool of available addresses.
I still think it's something we're overlooking or not aware of on the Mac
OS. Had another suggestion this morning to remove MacTCP and try using the
newer Open Transport instead.
