RFC1918 states the following blocks of IPv4 addresses that can be used in a Local Area Network. These are "private" address ranges that do not overlap with public IP addresses.
|Network/mask||Class||First usable addr.||Last usable addr.|
|172.16.0.0/12||Class B (x16)||172.16.0.1||172.31.255.254|
|192.168.0.0||Class C (x256)||192.168.0.1||192.168.255.254|
Active Directory (AD) integrated DNS zones are not replicated by the DNS server, but replicates through the Active Directory replication mechanism, and uses the same settings for AD replication.
You can trigger replication through Active Directory Sites and Services, or with repadmin.exe on command prompt:
repadmin.exe /replicate target_dc source_dc DC=DomainDnsZones,DC=domain,DC=com
Replace parameters accordingly:
A note of caution: when installing the Fortinet SSO Agent on a server, the option to secure connections from a FortiGate with a password is enabled by default, and a random password is assigned.
You have to turn off or change the password before you add the SSO agent in your Fortigate.
There's no mention of this in the manuals, so now you know...
Cisco AnyConnect VPN client may fail on Windows 7 for no apparent reason with the following error:
A possible reason may be that Internet Connection Sharing has been enabled on one or more network interfaces (e.g. used for making a hotspot out of your laptop). Try disabling ICS, then try connecting again.
If your Samsung Galaxy S5 may not find or be able to connect to a specific 5Ghz wireless network, you may want to check which channel the network is operating on. The S5 has problems when trying to connect to DFS-channels (Dynamic Frequency Selection).
DFS-channels are basically every channel from channel 52 and up. Try setting your AP to a channel between 36-48 (inc.), and then try reconnecting your S5.
I'ved noticed the Airport Configuration Utility from Apple requires "elevation" (= run as administrator) to work properly on a Windows 8/8.1.
If it still throws out an error after connecting, try disabling IPv6, then reboot.
SwitchExplorer for Brocade FC switches no longer works properly on more recent versions of Java, because of security constraints. They can, however, be relaxed so you can still access your switches.
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024
Note for Windows Vista and up: open the file elevated, or you won't be able to save it.
