Our company uses ISA2004 to manage Internet access and local area networks

Yes, dual network cards are required, one to connect to the external network and one to the internal network; Set the external network to the common IP, and set the gateway address of your internal LAN to the internal network.

Have you installed DNS Internet access rules or not, whether the ISA host is definitely able to access the Internet!

Two steps: 1. Rejoin the server where the ISA is located to the domain. The fastest way to change the domain name to netbios in the computer properties is to re-add it without exiting the domain. Or vice versa.

2. After the above operation, the client still needs to authenticate. You'll have to add this machine to the domain.

--Here are some empirical judgments:

This has happened before. That is, there are some problems with the domain, which depends on the replication log of the domain control, and the reason is that the domain is upgraded from the old system. In particular, the NT was upgraded to 2000, and then to 2003.

The second is DC, which is deleted abnormally. Residual Information.

The second is that there are too many ghosts on the client, and there is no re-SID closure.

There is no necessary connection between the two, what needs to be done is to clear the temporary password on the user's computer, which can be found from the control panel.

Right!!! You go to the IE on the user's computer that prompts you to enter the password, and you can clear all the saved passwords.

I know how to do it, click QQ login-advanced settings-network settings-type-address-port.

You can find these data to get the data, and then you can enter it when you log in, and that's it, and that's the case with our unit.

No, you need to change the ULR.

You're the one who goes to work.

The company restricts you from going on.

You and my answers, I will teach you how not to be hungry and let him limit your door.

can penetrate the firewall.

Piaoyun QQ seems to have this function.

Try to restore a one-poop computer, and reinstall one-poop QQ

QQ can be logged in via UDP and HTTP.

You can try to allow http mode.

I don't know how you network, 1) Extranet --- server -- switch -- LAN 2) Extranet --- switch --- server and LAN If it is 1, you can establish an intranet (internal) DNS server on the system and set the rules for LAN clients to access DNS. If it is 2, you need to bind the MAC address of the network card directly on the switch or router, and then you can take turns to assign different permissions to access the Internet according to the MAC address, and you don't know what brand of route you have.

ISA server.

Add protocol 123 to make all the protocols for different network segments, and you can access each other.

Company**:

。。。I've only tried one way. It's just that there is no other way to change the mac.

Because the ISA controls the MAC and the IP address binding. Unless you ask you to make the cloned machine not turn on. You need his MAC and IP address to access the Internet.

Otherwise you simply won't be able to do it.

Can't do it.

The principle is there. If you can break through, the ISA will be a garbage of garbage.

It is enough to let the network administrator make the corresponding strategy.

ISA does the strategy, you have no way to break through!! Because it's too powerful (I'm using it).

If ISA+VLAN, there is really nothing to break through!

You can also go to the Internet, my company can't connect to the Internet at all,
