We did just do it. The problem is that there is NO consistancy as to
what part of the network works when.

What do you mean by "part" of the network? If these are separate
BROADCAST domains then they need to be separate SUBNETS.

Show me the IPConfig /all from a machine that is having trouble AND
the IPCOnfig /all from a working machine on the same "part" of the
network.

Somtimes, we'll be able to get
out onto the internet from a new range without any problems,

What do you mean by "new range"? With that mask you have only
ONE RANGE or subnet.

Does your router have multiple network interfaces (NICs) so that
machines plugged into different ports are separated by a router?

Who manages your routers?

others we
can't access it at all. Same with accessing the domain and workgroups.
Some computers we can access, others we can't and that doesn't even
stay the same. Later in the same day we may be able to access a
previously inaccesable machine, and not reach ones we could before.
Does that make sense? We can not get the networking to work on a
regular basis ,and that's a huge problem for us.

Only if you have the router BETWEEN areas/stations which are
(incorrectly)
set
to be on your single subnet.

Sorry I'm having a terminology misscommunication.

The machines with the IP 190.10.10 addresses work fine amongst each
other (190.10.10 to 190.10.10).
When we give an IP of 190.10.11.x (or anything other than 190.10.10)
to a machine, it will lose the ability to reach the internet (router)
and a random selection of the 190.10.10 machines, but not always all
of the machines with an IP of 190.10.10.

But you are using a mask of 255.255.0.0 on ALL machines?
That would be correct if they are on the same physical network,
i.e., same broadcast domain, not separated by a ROUTER (layer3)
device.

A machine of 190.10.11 can see another machine with the IP of
190.10.11 regularly.
Does that make more sense?

Sounds like you router might separating the machines.

We presenlty don't have any managing much of anything. I would imagine
they'll be putting me in charge of the routers eventually (after I've
read up on them). Our comapny has a grand total of two IP folks and
me. The two of them are busy enough keeping the system in working
order that some things get neglected...

Here's the ipconfig from my test IP machine. I've tried a number of
combinatiosn with the DNS servers, but I'm not sure it would make much
difference. Thanks for the patience and the help.
Windows IP Configuration
Host Name . . . . . . . . . . . . : test-dc2
Primary Dns Suffix . . . . . . . :
IP Address. . . . . . . . . . . . : 190.10.11.56
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . : 190.10.10.12
DNS Servers . . . . . . . . . . . : 190.10.10.25
190.10.10.16

Is the above a working or non-working machine?

Show me the equivalent from the Cisco routers for each
interface? Who manages your Cisco router for you?

Give me the model number for the Cisco and describe its
hardware and configuration (NIC interfaces routing, bridging,
or switching WITH type: layer 2/layer 3).
