Microsoft apparently has a workaround which does not require enabling SMBv1, for those who rely on the ability to 'browse' the network.

https://support.microsoft.com/en-us/help/403431...

Explorer Network Browsing

The Computer Browser service relies on the SMBv1 protocol to populate the Windows Explorer Network node (also known as "Network Neighborhood"). This legacy protocol is long deprecated, doesn't route, and has limited security. Because the service cannot function without SMBv1, it is removed at the same time.

However, if you still have to use the Explorer Network in home and small business workgroup environments to locate Windows-based computers, you can follow these steps on your Windows-based computers that no longer use SMBv1:
Start the "Function Discovery Provider Host" and "Function Discovery Resource Publication" services, and then set them to Automatic (Delayed Start). When you open Explorer Network, enable network discovery when you are prompted.

All Windows devices within that subnet that have these settings will now appear in Network for browsing. This uses the WS-DISCOVERY protocol. Contact your other vendors and manufacturers if their devices still don't appear in this browse list after the Windows devices appear. It is possible they have this protocol disabled or that they support only SMBv1.

- Try browsing to some of the computers manually, press Windows key + R, type: \\computername, hit Enter
- Press Windows key + R
Type: services.msc
Hit Enter

1. Start the "Function Discovery Provider Host" and "Function Discovery Resource Publication" services, and then set them toAutomatic (Delayed Start).
2. When you open Explorer Network, enable network discovery when you are prompted.

Press Windows key + X > computer management-->shared folders--> choose the shared folder, right click it then click Properties > Share Permissions -->protection that everyone can read and execute, see folder contents and read permissions.

cara set sinkronisasi waktu di windows server 2003 dan 2008

https://timetoolsltd.com/time-sync/how-to-synchronize-microsoft-windows-to-a-ntp-server/ 

Microsoft Windows Server 2008, Server 2003

To configure a Windows PDC to synchronize with an external NTP server requires registry entry changes. When modifying registry settings, it is always a good idea to backup the current settings beforehand. Backup and modification of the registry is easily achieved using the ‘regedit’ utility, which can be run from the command line. You can revert back to previous settings if any problems occur with registry changes. Use the registry editor ‘regedit’ to change the following entries:

1. Change the server type to NTP.
Registry Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
Change value data to: NTP

2. Set announce flags.
Registry Key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags
Change value data to: 5

3. Enable NTP server
Registry Key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer
Change value data to: 1.

4. Specify the time sources.
Registry Key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
Change value data to: <peerlist>
<peerlist> is a list of space-delimited NTP peers from which time can be received. If DNS names are used, you must append ‘,0x1’ to each DNS name. Alternatively, a list of IP addresses can be specified.

5. Select poll interval.
Registry Key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient\SpecialPollInterval
Change value data to: <period>
<period> is the time in seconds between each poll. Microsoft recommends a value of 900, which equates to a polling frequency of once every 15 minutes.

6. Set the time correction settings.
These settings specify a time frame to validate time stamps received from an external reference. Only if the received timestamp falls between these registry settings will they be accepted. It provides a facility to reject timestamps that are too far away from the hosts system time. Microsoft recommends a setting of 1 hour (3600) or 30 minutes (1800).
Registry Key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\MaxPosPhaseCorrection
Change value data to: <seconds>
Where <seconds> is the maximum positive offset of the received time stamp from the system time.

Registry Key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\MaxNegPhaseCorrection
Change value data to: <seconds>
Where <seconds> is the maximum negative offset of the received time stamp from the system time.

7. Restart the windows time service.
Stop and restart the Windows Time Service using the ‘net stop’ and ‘net start’ commands:
net stop w32time && net start w32time

Problem This share requires the obsolete SMB1 protocol di windows 10

SMB 1.0/CIFS File Sharing Support Option

Merubah network category pada windows 10 menjadi domain, private atau public

 Cari network yang ingin dirubah di :
 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles

Cari profilename yang ingin dirubah, Lalu rubah nilai category berdasar nilai berikut:

Network Location	Data Value
Public	0 (zero)
Private	1
Domain	2

caranya itu, tapi nggak kelihatan efeknya

1. Open PowerShell as Administrator.
2. Type or copy-paste the following command:

   Get-NetConnectionProfile

3. In the command output, see the line "Name". It contains the name of your network which you need to use with the next command.
4. To set the network location type to Public, type or copy paste the following command:

   Set-NetConnectionProfile -Name "Your Network Name" -NetworkCategory Public

   Replace the "Your Network Name" with your actual network name you got from the previous command.

instalasi / migrasi server email dengan Ubuntu 12.04 LTS, postfix dovecot, squirrelmail

 Set network ke yang bisa internetan.

Setel /etc/apt/sources.list agar bisa update, misal ke alamat old-releases.ubuntu.com. untuk ubuntu 12.04:

deb http://old-releases.ubuntu.com/ubuntu/ precise main restricted multiverse universe

deb http://old-releases.ubuntu.com/ubuntu/ precise-updates main restricted multiverse universe

jalankan satu satu :

apt-get update

apt-get upgrade

apt-get install ssh apache2 php5

apt-get install postfix 

Perhatikan setelan dari /etc/postfix/main.cf terutama untuk (asumsi nama domain adalah bagus.com), dengan network lokalnya 192.168.xxx.xxx:

mydomain = bagus.com

myhostname = mail.bagus.com

myorigin = bagus.com

alias_maps = hash:/etc/aliases

alias_database = hash:/etc/aliases

mydestination = localhost, bagus.com

mynetworks = 127.0.0.0/8, 192.168.0.0/16

smtpd_sasl_exceptions_networks = $mynetworks

relay_domains = $mydestination

header_checks = regexp:/etc/postfix/header_checks

file /etc/postfix/header_checks contoh isinya:

/^Subject: .*been hacked/ DISCARD 550 User unknown

/^From: .*SureVoIP/ DISCARD 550 User unknown

Lalu jalankan untuk dovecot

apt-get install dovecot-core dovecot-imapd dovecot-pop3d

dil file /etc/dovecot/conf.d/10-auth.conf kalau tidak ingin pakai TLS:

disable_plaintext_auth = no

auth_mechanisms = plain login

di file /etc/dovecot/conf.d/10-master.conf, hilangkan # di contohnya IMAPS:

inet_listener imaps {

    #port = 993

    #ssl = yes

  }

di file /etc/dovecot/conf.d/10-mail.conf boleh pakai:

mail_location = mbox:~/mail:INBOX=/var/mail/%u

Jalankan perintah 

squirrelmail-configure

Terutama untuk bagian server, pilih model dovecot untuk IMAP servernya. Lalu jalankan:

cp /etc/squirrelmail/apache.conf /etc/apache2/sites-available/squirrelmail.conf

a2ensite squirrelmail.conf

service apache2 reload

Jalankan squirrelmail lewat http://alamatnya/squirrelmail

Kalau misal migrasi, bisa copykan isi /etc/passwd dan /etc/shadow ke komputer yang baru, tapi editnya pakai vi . 

Karena user baru nggak ada home, maka setel:

chmod 777 /home

chmod 777 /var/mail

kalau untuk forward port dari luar bisa pakai /etc/iptables.rules
