Hi Randy, the subnet mask is used to identify which part of the IP address
is the network address and what part is the host address. When a bit is set
to one, it is considered to be part of the of the network address and when
it is set to zero it is considered to be part of the host address. The
exception to this is documented in RFC 950 which describes a standard
procedure for subnetting using unused bits that had been part of the host
address ( and were always set to zero and unused). The subnets you posted,
1111 0001 0010 0011 and 1111 0011 0010 0001 are uncommon however they
could be utilized for a specific TCP application that depends on subnetting
via the subnet mask. While I agree, the most common subnet mask is 255 255
255 0 ( or 1111 1111 1111 0000 ), one needs to ask, are you running an
application that utilizes some form of subnetting via the subnet mask? If
the answer is no, then based on your current IP network address, the most
common subnet mask would be 255 255 255 0 because the high order bits are
or'ed together to form the mask for the network address meaning it's best
to keep them contiguous.

Due to all the help and interest I'll come back to the list.
Thanks Richard for the tip on IPX and NETBIOS. I have never seen the other
computers in Network Neighborhood and now I do. IPX was already installed
but not netbios. I encountered a missing file nwnblink.vxd as I selected
the netbios on the 98 machine. I'll have to locate this file.
Also thanks to Rob and Karl for tips.
Results are still no connection. I'll summarize for all interested. (2
98 Machine IP 169.254.144.195 95 machine IP
Shows both in network neighborhhod Shows both in network
Ping to 95 machine OK Ping to 98

get dial up connection window and close it
get connect failed
hover over VNC icon and see correct IP as set Try to connect from
IE Explorer by entering 169.254.144.195
get dial up window then connect failed
I also have set subnet mask of 255.1.2.3 on 95 machine and 255.3.2.1 on 98
I think the problem is in the dial up connection always taking over any
attempt to connect.
