Copy and paste is fine, screenshot too. Does her machine have an IP assigned from DHCP? ipconfig tells you this. Can she ping her own IP. CAn she ping the gateway IP? Can she ping an IP beyond the gateway? Can she ping via FQDN (servername)? Does the servername at least resolve to an IP?

DHCP generation? NEver heard this term before.... is it a DHCP server and you can disable it?

It should be 2 way traffic.

Was the file on a network server? IF yes, the file may be shadowed and versioned so that you can recover different versions from the file properties.

So in that Adapter page, there is a tab for DHCP. Make sure the settings here are correct.

If everything worked, the guest OS gets an IP address from this pool. The Host OS also has a host only adapter with an address int he same range. Use IPCONFIG from a command prompt to check IPs.

IF they have IPs in the same range, PING the IP of the other host.

With a Virtual box 'host only' interface assigned to the Guest VM, you would receive an IP address from the HOST ONLY ADAPTER that you configured in virtual box on the HOst OS. To Check this, Open up Virtual Box, Goto FILE -> PREFERENCES -> NETWORK. Do you have a Host-only adapater listed here? If you don't, you need to create one. When you do, you can pick the subnet and DHCP server options. With that, when you boot a VM with host only adapter, it will dhcp from the settings you just defined.

What do you mean by inducing filters? Excel will read in a text file and give you options on separating items into cells using delimeters (i.e. CSV). What are you trying to do here?

Maybe he means something along the lines of how a Linux server would do this, where the network resource would be mounted to the server, then the mounted filesystem could be shared from the server? Don't think you can do that with windows server. RRAS as JorgeM mentioned would be the solution there.

Use a live CD, mount the drive, and inventigate.

IS this some kind of homework assignment?

Google "how to use postfix"...

Any router you buy today will be able to handle your 6mb ISP connection. Don't worry about that. Concentrate on the other router features you would want. Such as # of LAN ports, QoS, VPN, etc...

I think maybe he's asking for the details on how to become a CCIE while in Dubai?

1st thing is to get the latest drivers for your wifi adapter. Usually had from the manufacturer's website.

Who is your email provider? Gmail? Somebody else? The info you need should be easily had from the host's website or forums. Also, as a side note, most hose ISPs block outbound port 25. So you probably need to and should use SMTP over 587.

Well, then I guess verify the account that the backup is running with, and test it manually during that time window. That would be my next step.

MAC addresses do not change on on physical hardware. Nor should they change on the fly with DHCP.

How about any event log entries at or about 2 AM? It's an odd issue...

Check the routing on both the IPsec client and the anyconnect client. It's easy to see if split tunnels are used. A route of 0.0.0.0 means tunnel everything, any other route would only tunnel the matching traffic.

Also "I lose internet and dns" do you mean that you can send traffic out to the internet like a 'ping 4.2.2.2' or that you just can't browse websites indicating that DNS is not working. Cisco VPNs allow the admin to override your DNS settings such as pushing the company DNS while you are connected. While on VPN, run an nslookup. Do you get a dns server? is it internal or external? Enter www.google.com or something and does it resolve? If it is internal, switch to external with 'SERVER 8.8.8.8' and run the same lookup. What do you get here?

Ok weird... During the backup window, can you sign into the host and access e:?

Any other tasks on this host that might 'shuffle' drive letters?

Actually, in Windows 7, the administrator account is disabled by default. During the initial setup, the end user must pick a username with password. That username is granted administrative rights. Now, you can certainly go in and re-enable the administrator account if you wish, but it is not automatic.

So, if you don't have the account and password, you can try the recovery tools JorgeM mentioned, or do a clean installation.

What is the E drive then? iSCSI, local disk, other?

Are there time restrictions on these accounts that allow logons during the work week, but no access during off hours?

You can't 'bridge' a modem, it's already passing through the connection.

What I keep mentioning is that if a PC plugged into the modem (no router) works, then the PC must have some settings configured. All you need to do if find and copy the important information to the router.

It seems the host and guest have the same Mac Address

Ya that's going to be a problem... Normal flow for this is to ARP for the MAC belonging to an IP address via broadcast. Owner of the IP will respond back and the local ARP table will be updated. If 2 IPs share a mac, I'm not sure how the traffic will react to that.

However in this case, I only see the following:
16:43:31.834932 ARP, Ethernet (len 6), IPv4 (len 4), Request who-has 192.168.1.110 tell 192.168.1.1, length 46
16:43:31.834970 ARP, Ethernet (len 6), IPv4 (len 4), Reply 192.168.1.110 is-at 52:54:00:fa:74:0e (oui Unknown), length 28

I never see an ARP request for 192.168.1.119 for the HOST OS IP. Was this tcpdump taken from the guest? If yes, can we get the same thing done from the host OS.

Can you have each host ping the other host while TCPDUMP is running on each. Then print the arp tables from each.

Bottom line, if both hosts share a MAC, then you need to correct that somehow.

Can each machine ping itself at their own addresses (192.168.1.119 and .110)?

Can each machine ping the gateway at 192.168.1.1?

Can you show the arp table from each host after the ping attempt?

On the guest, run a tcpdump -v and then ping it from the host. The tcpdump should show the inbound packets at least. I'd like to see that as well.

Agree with you there.... this is an odd odd odd request.

To block just the google images web site, it would be easy enough to block the dns lookup with a hosts file entry or a simple URL block on the perimeter router. Blocking all images from all sites seems crazy to me.

Sooo..... you good then?

Cat-5e/Cat-6 have a maximum distance of 100m or about 325 ft. IF you need to go that far, you need to think of fiber or using repeaters.

To you have the script language defined in the 1st line to be php? From command line, do you just run './SSC.php' and it runs or do you pass it into the scripting language module? Does the script have new external commands that require permissions that the id running this cron doesn't have?

Alright then. Lets start with the host OS.

Is there a firewall enabled on either host? If yes, disable for a test.
Can host OS ping the guest OS using that bridged IP?
Can we see ipconfig /all or ifconfig for each host...
Can we also get a route list for the host os.

On a computer that worked, look in networking, the conenction type that is in use for the internet is what we want to look at. If the connection is PPPoE, the computer should reflect that.

Here's the guide for you unit:

IT says:
You will need the following data from your ISP (Internet Service Provider) to
install the Cable/DSL Router:
•Your broadband-configured PCs’ Computer Name and Workgroup Name
•Your broadband-configured PCs’ fixedInternet IP Address
•Your Subnet Mask
•Your Default Gateway
•Your Primary DNS Server IP address(es)

The installation technician from your ISP should have left this information with
you after installating your broadband connection. If not, you can call your ISP
to request the data

http://lmgtfy.com/?q=How+to+setup+windows+2008+IIS+for+web+hosting

We need lots more info on your setup and what other tests you've run before I can even wager a guess.

JorgeM is correct, That is the MS Textbook way of handling that scenario.

YOu would need to boot with Windows 7 media and run a repair on the win7 installation.

Well, the drive can be identified, but the boot partition or MBR could be hosed making it unbootable. Have you tried the disk in another machine? Can you boot with a live CD and check that the disk is readable? How about a Windows install media and run a repair (won't hurt anything).

Don't listen to the tech, he's an idiot.

You need the modem. The modem must have rj11 on one side to the wall for service, and a single RJ45 ethernet port on the other side for you LAN. From the Modem, you plug into the router's WAN port, everything else goes into LAN. I think you have this setup already.

Without router, a PC can use the modem perfectly to get outbound. How is the PC configured? DO you just plug it in and it works? Do you need to run a PPPoE client? Is there software. How you setup a PC will determine how you setup the router. Both will use the same method to authenticate to the DSL service. This is the info you need for the router.

If the router is completely hosed, you can always opt to reset the router and start over. Only do this if you can't access the router's web interface from the LAN.

If you have trouble, you can find me in the daniweb chat room.

Maybe he means Create the Scope and then add in exclusion of ranges within the scope?

1) Do you ping by name or by full fqdn. In MS, serve1 is different than server1.domain.com.
2) Do you have WINS enabled on any host(s)?
3) HAve you checked local hosts file?
4) Have you checked lnhosts file?

Run nslookup and ping the name what do you get?
Netbios had its own command line lookup which I can't remember right now, something like NBTSTAT.
Trying to isolate DNS vs NetBios resolution here.

Strange sounds from a hard drive are never good. HArd clicking = dead drive. Did the disk show in dmesg?

Like what, 2 factor authentication? Rfid and a passcode? CAn you imagine the line of students to get into a lecture hall when 1 forgets his pin and needs a reset?

You can try "sfc /scannow" from administrative command line, or just run a repair from the install media as indicated above.

I dont think you get that level detail.

Also, to restrict what users can sign into what machines, you use the PC's local security policy in:
Local Policies -> User Rights Assignment -> Allow log on Locally.

You'll want to leave administrators on there, and remove Users and guests, and then add in the domain\username for those allowed.

I've done this for C-level Execs in the past and it works well even if it is a an administrative headache.

IF this were me, i would remove the hard drive from the laptop. I have a USB to sata/ide adapter so I can plug in any hard drive to another computer and have it show up like a USB disk. The adapters are like $15 and a needed tool nowadays. Plug it in to another PC and see if it spins up and is recognized. Does it spin? Does it click loudly? Does it show in Disk manager in win or dmesg in linux?

If the disk is unreadable, you need to get a new disk and reinstall the OS then restore your data from backup.

Duplicity seems to be a popular solution for this. I've not used it personally, but the docs claim it can backup directories and encrypt with GPG key or passphrase.

http://manpages.ubuntu.com/manpages/hardy/man1/duplicity.1.html

Well, first off, never listen to ATT tech support. They are 1st level technicians who read triage.

Let's start with your type of service, model of modem? Is modem in bridge or router mode? PAste the config of the router here (removing personal details).

Well, before you can troubleshoot the connectivity, you need to fix the networking and get an IP assigned to that virtual host.

I don't follow that last post....

Without an IP on the bridged interface, how would this work? It won't.
