1
00:00:01,140 --> 00:00:04,480
In this demonstration, we'll take a look at BranchCache,

2
00:00:04,480 --> 00:00:08,060
and I will, again, come to our Server Manager dashboard,

3
00:00:08,060 --> 00:00:11,040
and let's just quickly take a look at the specific

4
00:00:11,040 --> 00:00:13,090
roles and features that we need here.

5
00:00:13,090 --> 00:00:16,310
I'm on localmem1, and if we browse the list here,

6
00:00:16,310 --> 00:00:18,770
we have under File and Storage Services,

7
00:00:18,770 --> 00:00:23,140
File and iSCSI Services, we have BranchCache for Network Files,

8
00:00:23,140 --> 00:00:27,390
and this is what you're going to need for the file server BranchCache scenario,

9
00:00:27,390 --> 00:00:29,300
That's what I definitely want to do.

10
00:00:29,300 --> 00:00:31,740
If we click Next and take a look at Features,

11
00:00:31,740 --> 00:00:35,120
this is where you have the BranchCache feature, and this is what you

12
00:00:35,120 --> 00:00:38,960
would use for either the web server or the bits context.

13
00:00:38,960 --> 00:00:42,700
I think I misspoke earlier in the slides where I said that

14
00:00:42,700 --> 00:00:45,820
you needed branch cache for files for HTTP.

15
00:00:45,820 --> 00:00:49,270
No, you do branch cache for files only for the file server,

16
00:00:49,270 --> 00:00:51,080
the hash distribution scenario,

17
00:00:51,080 --> 00:00:56,180
and then we need this guy here if we're doing bits or the HTTP web server.

18
00:00:56,180 --> 00:00:57,580
So I've got that installed.

19
00:00:57,580 --> 00:00:59,900
Now, the two ways that this is going to surface,

20
00:00:59,900 --> 00:01:02,200
like I said, is number one in Group Policy,

21
00:01:02,200 --> 00:01:04,240
so let's go into my MMC here,

22
00:01:04,240 --> 00:01:09,190
I've got a domain‑scoped policy ready to go here called BranchCache Policy.

23
00:01:09,190 --> 00:01:10,440
Let's edit this.

24
00:01:10,440 --> 00:01:14,140
And the path we're looking at here is Computer Configuration,

25
00:01:14,140 --> 00:01:17,280
Policies, Administrative Templates, Network,

26
00:01:17,280 --> 00:01:21,710
and if we go to Lanman Server, if we're going to do BranchCache for files,

27
00:01:21,710 --> 00:01:26,190
we have to enable the Hash Publication for BranchCache on your content server,

28
00:01:26,190 --> 00:01:27,700
and that's going to be enabled,

29
00:01:27,700 --> 00:01:32,140
and we can choose here Allow hash publications for all shared folders,

30
00:01:32,140 --> 00:01:36,820
Allow hash publication only for shared folders on which BranchCache is enabled,

31
00:01:36,820 --> 00:01:39,000
or Disallow hash publication.

32
00:01:39,000 --> 00:01:40,960
Well, I don't want to go crazy because this is,

33
00:01:40,960 --> 00:01:42,360
you know, CPU overhead,

34
00:01:42,360 --> 00:01:45,200
so I'm just going to do hash publication for shared

35
00:01:45,200 --> 00:01:47,340
folders that have BranchCache enabled,

36
00:01:47,340 --> 00:01:49,360
and I'll show you how to configure that as well.

37
00:01:49,360 --> 00:01:54,080
The other options are under the same path network, here, under BranchCache.

38
00:01:54,080 --> 00:01:57,550
And number one, we have Turn on BranchCache on clients.

39
00:01:57,550 --> 00:02:00,440
This would be in your GPO that's going to affect

40
00:02:00,440 --> 00:02:02,610
your client or consumer machines,

41
00:02:02,610 --> 00:02:06,190
and so we want to enable that for any domain workstations

42
00:02:06,190 --> 00:02:08,270
that'll be relevant in your branch offices.

43
00:02:08,270 --> 00:02:11,330
And then the help here tells us that we also have to

44
00:02:11,330 --> 00:02:13,930
configure what topology we're going to use.

45
00:02:13,930 --> 00:02:17,110
Are we using Distributed Cache, Hosted Cache, or what?

46
00:02:17,110 --> 00:02:18,900
Well, we've got that in here as well.

47
00:02:18,900 --> 00:02:22,430
Set BranchCache Hosted Cache mode, we enable that,

48
00:02:22,430 --> 00:02:24,830
and type the name of your hosted cache server.

49
00:02:24,830 --> 00:02:28,760
Now, presumably if you have a complex environment with multiple branch offices,

50
00:02:28,760 --> 00:02:33,240
you're going to have multiple GPO's with multiple hosted cache servers here.

51
00:02:33,240 --> 00:02:35,360
That's a single server reference here.

52
00:02:35,360 --> 00:02:39,050
And I would recommend you use a fully qualified domain name like I did.

53
00:02:39,050 --> 00:02:39,660
Lastly,

54
00:02:39,660 --> 00:02:43,260
to make sure that the BranchCache service is as easy to

55
00:02:43,260 --> 00:02:45,800
find in Active Directory as possible,

56
00:02:45,800 --> 00:02:50,220
we have Enable Automated Hosted Cache Discovery by Service Connection Point.

57
00:02:50,220 --> 00:02:54,390
This makes it easier for your client computers to determine the

58
00:02:54,390 --> 00:02:58,110
BranchCache setting of their file server in their location.

59
00:02:58,110 --> 00:02:58,270
See,

60
00:02:58,270 --> 00:03:01,250
so I wasn't kidding when I said that you configure the line

61
00:03:01,250 --> 00:03:03,990
share of your BranchCache through Group Policy.

62
00:03:03,990 --> 00:03:08,370
Lastly, we can come here in Server Manager to the File and Storage Service,

63
00:03:08,370 --> 00:03:12,640
let me focus on localmem1, and we'll go to the Shares panel here,

64
00:03:12,640 --> 00:03:16,410
and we can either create a new share directly in Server Manager,

65
00:03:16,410 --> 00:03:19,460
or we can modify the properties of an existing share.

66
00:03:19,460 --> 00:03:22,510
So here, we can browse localdc1and localmem1.

67
00:03:22,510 --> 00:03:27,100
Let me right‑click new‑hire‑paperwork, go to Properties on localdc1,

68
00:03:27,100 --> 00:03:29,090
and if we go to Settings,

69
00:03:29,090 --> 00:03:32,240
notice that we can choose to Allow caching of share and

70
00:03:32,240 --> 00:03:34,480
Enable BranchCache on the file share.

71
00:03:34,480 --> 00:03:36,300
And this is important because you'll recall I

72
00:03:36,300 --> 00:03:39,880
designated localdc1 for hash distribution.

73
00:03:39,880 --> 00:03:44,840
So that's how you can mark a shared folder as being available for BranchCache,

74
00:03:44,840 --> 00:03:46,780
and the users don't have to do anything.

75
00:03:46,780 --> 00:03:50,790
They can navigate to that share inside or outside of DFS,

76
00:03:50,790 --> 00:03:53,700
and the BranchCache policy that you've specified,

77
00:03:53,700 --> 00:04:01,000
hosted cache or distributed cache, will take effect. Let me click OK to complete that configuration.
