    AD Root question... possible DR issue

    Hey techies. Let me describe our scenerio, and see if my fears are solid. Toyota Canada connects to Toyota North America, which is in the states, and is the root of our forest. We connect via a T1, purely for AD replication. We've opted to add a hot DR site about an hour from our HO, and...

    Backup WAN... how did you resolve dns issue?

    Hey techies. We have an ISP that continues to let us down, so I've been asked to investigate adding a backup ISP to the mix. The issue that I forsee is that we host our own sites. So picture this... ISP A drops the ball again, and our sites disappear to the public. The border router detects...

    Device package/diagrams?

    Subnetting a Class A addy

    All the user vlans are using the same mask, while the router/switch interfaces are using 255.255.255.248. Does that help? Mike

    Subnetting a Class A addy

    Need some help with this one, folks. My LAN has a mask of 255.255.252.0. I am using an IP of 10.22.201.30... a class A address. Based on the breakdown of the 252 portion of the NetID (11111111.11111111.11111100.00000000), with the last used subnet bit falling on '4', I'd expect an increment...
