Hi can someone help me answer some of this Networking questions. Please help me please because this question are due tommorow!

Thanks!!


Q)As a consultant for the First National Bank of Monroe, you have been asked to solve a problem on the bank’s network that began on Monday. According to the bank manager, at the beginning of each day two of the 16 tellers have been unable to log on to the network. Two other tellers occasionally experience problems at the beginning of the day, but not if they get to work before everyone else. They receive an error that says something like “another machine is using that name.” When you arrive at the bank, the college intern who has been setting up the machines tells you that he is using a program called Ghost to clone all PCs from a single disk image. In other words, an exact copy of one machine’s software, operating system, and its properties been copied to all of the computers. All of the PCs are brand new, are running Windows 98, and use the same hardware and software. First National Bank’s network consist of two Windows 2000 server and runs both TCP/IP and NetBIOS/NetBEUI protocols. It uses DHCP to allocate TCP/IP addresses. What might be preventing two tellers from logging on to the network in the morning?

Q)First Nationals Bank share the information that she’s about to make an offer to buy Monroe’s other bank Metropolitan Savings. She’s worried that the two banks’ networks won’t integrate easily. She isn’t sure what kinds of server or workstations are used by the other bank, but Metropolitan Savings’ manager mentioned something about a network that relies on the Internet. What can you tell her about integrating the two systems? What protocol would you recommend that she use or continue to use facilitate the integration process?

Q)Six months later, First National Bank has successfully consolidated the networks at its original location and at its new acquisition Business is booming, and the bank is investigating the possibility of allowing customers to check their account balances form the Web. However, the bank’s president tells you the bank doesn’t have its own connection to the Internet at this time. She understands that she needs to obtain IP addresses for all of her machines. But, she says, they are already using IP addresses internally and they work well without having to pay ICANN for new IP addresses. Would you recommend leaving the bank’s IP addressing as is or changing it? How do you suggest that the bank obtain Internet access? What concerns would you bring up with regard to allowing customers access to their account information off the Web? How might Internet access affect the bank’s internal LAN?

Hope this is not too late for your homework.

A) Quick answer: Norton Ghost. Since the college student used Ghost to duplicate machines, he also replicated network setings on each machine. The server won't allow two clients with the same name on the same network segment. Well, technically it shouldn't matter, since they are using DHCP, but when you are trying to resolve the client names (which you shouldn't anyway in an DHCP environment) it doens't know which IP to resolve to.

Q)First Nationals Bank share the information that she’s about to make an offer to buy Monroe’s other bank Metropolitan Savings. She’s worried that the two banks’ networks won’t integrate easily. She isn’t sure what kinds of server or workstations are used by the other bank, but Metropolitan Savings’ manager mentioned something about a network that relies on the Internet. What can you tell her about integrating the two systems? What protocol would you recommend that she use or continue to use facilitate the integration process?

A)Network that relies on the internet? Not sure. Perhaps this eludes to TCP/IP protocol, but also may be also VPN (virtual private network) or Tuneling network.

Would you recommend leaving the bank’s IP addressing as is or changing it? How do you suggest that the bank obtain Internet access? What concerns would you

A) There are of course two ways to do this. Get ICANN public addresses for all machines. Now that all the machines are connected to the public network. One should worry about security. Setup one firewall machine, and tunnel all traffic thru this firewall. Block un-needed ports/protocols.
OR
Use NAT (network address translation) to connect the internal network to the public network. The internal machines continue to use the internal addresses, outbound and inbound traffic are routed thru the NAT server. This way, the internal addresses are not known to the outside, minimizing the risk of security problems. I would still use a fire-wall.
In either case, lock down the fire-wall, NAT server and allow as little access as posible.
As far as recommendation, I would have to go with NAT solution. Save money, and increase security.

Hope that help.
