critters,
00:12
just a discussion of printers here.
00:14
If I go to add a printer,
00:20
I have two choices. The local printer or a network printer.
00:24
And there's some discussion about what a network printer is.
00:41
If I have a laptop over here,
00:47
I have a server over here
00:54
with the printer are hanging off of it,
00:59
and I have another printer down here
01:07
that stand alone and has its own I P address on it.
01:11
And if these were all connected together
01:19
so everybody can see everybody
01:23
if I want to install
01:26
this printer over here,
01:30
this is a never surrender.
01:34
The reasons in our printer is that the printer itself, the print device
01:41
is which is Microsoft's term for it.
01:44
The print device with Ian cartridges and everything is controlled by some
01:52
server or is tell me
01:53
system on the network.
01:57
However, this printer down here, the bottom,
02:00
even those on the network.
02:02
If I go to install it on my system, it's a local printer,
02:07
and the reason is there's no control device
02:09
between this printer
02:13
in my laptop
02:15
and without a control device. When I print to it, my laptops talking directly to the printer.
02:22
So it's local to that printer in terms of who's got the control
02:25
the local laptop has to control.
02:29
Over here,
02:31
my laptop talks to the server
02:37
and the server talks to the printer.
02:38
That's what creates it as a network device.
02:43
So if we go back and take a look at
02:45
my system again,
02:51
no.
02:52
If I go to add a network printer
02:54
and a hit network,
03:00
it's going to come up. And it's going to be in looking for
03:08
printers that it confined
03:10
and the server they're connected. Thio.
03:16
And if I browse for a printer,
03:21
it's looking for a computer name.
03:30
But if I go back and do and a printer at a local friend, er
03:35
and I tell it that I want to create a new port,
03:39
I created T C P I. P Port,
03:43
and that's when I'm gonna go directly to the I. P address of the print device,
03:46
and I'm gonna talk to if he's there
03:50
to the print device
03:51
and because my laptop is controlling the printing to that device.
03:55
And there's nobody else in between me and the printer. It's a local printer because control was handled locally on my laptop,
04:03
so it's not whether it's plugged in directly to you or where there's down. An Ethernet cable is who's controlling sending the printing to the printer.
04:14
If our servers doing it, then it's a network function, and I'm talking to the server in the server. Talk to the
04:19
praetor.
04:23
If my laptop's talking directly to the printer,
04:26
then I'm in control and it's local to me for control,
04:31
just something that comes up
04:36
and the way you can tell
04:40
ISS.
04:47
I go to this device, for instance,
04:50
and I would pull up the properties.
05:00
I don't get the port
05:02
I'm sending directly to an I P address here
05:11
1 81 61 to 51.
05:15
So to me, that's a local printer.
05:31
So Windows firewall
05:35
control panel
05:39
and in Control Panel, you can see a whole bunch of things to look at
05:44
again. It's good to go in
05:46
and just kind of poke around. Here's another way to get the device manager
05:51
Same device manager.
06:01
Internet options.
06:06
This is the actual the options for a new next four.
06:11
That's how you can get to them
06:16
pro programs and features.
06:21
This is what in Windows X P was add remove programs.
06:27
It is good to go in here times and say, Why do I have this happen here?
06:31
Why do I have that happen here?
06:34
Did I just quick on this one day and accidentally get it
06:38
like Google toolbar for Internet Explorer?
06:41
If you don't want that,
06:44
then right click and hit on install.
06:51
So now it's saying there's another user log into this computer and I'm saying Continue anyway.
07:04
Yep.
07:05
And Google doesn't want to uninstall until it can talk to itself.
07:10
So we'll bypass that
07:26
and down here, the bottom Windows firewall.
07:32
And you can see it's not just that the fire walking we turned on or off
07:38
is that the firewall can be turned on or off
07:42
for he to those three options.
07:48
So do I want it on for domain settings,
07:51
homer work settings or public network locations.
07:56
So public network location would be something like, um, accessing
08:01
Internet, an airport er in Starbucks.
08:03
Well, you have absolutely
08:05
no knowledge of who else is on the network or what threats might exist
08:11
in a home or private network setting.
08:15
You can be a little more free because you're a little more likely to want to access a printer or share a printer. Or let somebody else come on your machine and get a file.
08:24
And if you're in the domain setting you, the main idea here is that in the domain network setting have probably the most trusted setting because it's a Maness environment
08:35
with other people whom you trust,
08:37
or at least other people who are managed.
08:41
So you can. When you want to turn off the firewall, you can turn it off for one or all of these settings.
08:48
And with the domain, home or public
08:52
is actually related. Thio
08:56
Oh, and sorry. You can also go in here,
08:58
and
09:03
there's a button here to restore defaults.
09:05
The reason you need a button to restore default is because there's a button here for advanced settings,
09:11
or you can go in right inbound and outbound rules.
09:13
And if you happen to break one of these connections,
09:18
then I'm taking you back to the defaults
09:22
and what we're looking at here are different traffics that allowed in and out
09:26
file transfer program hates peewee
09:30
printer install wizard Internet Explorer.
09:33
So it's not just does the system works is that there are a lot of things here that it has specifically allowed to communicate one direction or another.
09:48
And if you find something is blocked by your firewall or you think it's blocked by your firewall, one way to deal with that
09:54
is temporarily going here
09:56
and
10:05
just open the firewall of everything.
10:09
Turn the fire off.
10:18
So say off.
10:20
Uh uh,
10:22
once you've done that, if your application or whatever your troubleshooting works
10:28
and then you turn these back on and it breaks again,
10:31
then you're pretty sure that you determine the firewall is the issue.
10:35
You could then go into the logs
10:37
or going to net stat
10:39
and see what traffic actually is.
10:43
And that's a point where you can come back here into advanced settings
10:46
and this created new rule.
10:54
And with the new rule,
10:56
then you can
10:58
create another
11:01
instance
11:03
or another Apple case and that you're running her out.
11:13
So here's where you can create rules.
11:16
So the idea is, go ahead and use the on off
11:20
on firewalls headings to test
11:24
to make sure that the firewalls the problem. Once you know the fire Walter problem, don't just leave it off. Actually configure it to allow the permitted traffic through, and then turn it back on.
11:35
So I'm gonna go
11:37
back to the first set of rules here
11:43
and take a look at this one last time.
11:46
Mmm.
11:48
All of these items you should have some familiar
11:52
familiarity with
11:54
how would recommend you go into each one of them
11:56
and at least poke around to see what the settings are
12:00
and then used the Internet to use Windows, help
12:05
use Microsoft documentation upon their sight
12:07
and get some feel for what each one of these processes runs
12:20
and then some of them. You also need to remember our platform specific
12:24
and the ones that platform specific you should remember their part for specific
12:31
in case
12:33
it matters to you why you can't find something out one system and you can on another,
12:48
especially looking at things like Home Group will talk about home group.
12:52
Home group is a special setting, the kind of replaces the workgroup function
12:58
and in laws used to create a interconnected home network,
13:16
they were sure mapping.
13:18
I'm going to
13:26
I wouldn't convert this back for a minute
13:33
right now. I'm gonna let you see that
13:46
I was long gone as two different people right now. One session
13:50
for the administrator.
13:52
One session for J. Mays.
13:54
I'm gonna go back into the game a session.
14:16
J. Mays is connected to
14:18
a wireless network,
14:26
and
14:33
if I do this because I know the
14:37
address of a particular server,
14:43
I'm getting challenged now. But if I know the right commands to put into this,
15:30
I can now see some shares.
15:33
These shares are from a server running on running in this environment.
15:39
If
15:39
I want to take this share
15:43
called Resource Is
15:43
and let's say I want to make it a permanent Dr Water so I don't have to go through this every time I want to find it.
15:50
Then I can map a network drive
15:54
and let's say I want to call this one
16:00
just for final call. Q.
16:07
Now that I've done that, if I go back to
16:18
computer,
16:22
I know I have a new drive called the Q Dr
16:25
and the Cook On the cue. Dr. Notice it's got a
16:27
wire connected to a hard drive that's hard drive over wire or network storage,
16:37
and now I'm pulling
16:40
items from a server not on my computer.
16:45
So those air shares
16:47
and that is a shared Dr
16:48
and had a map, a shared drive to
16:51
Dr
