VM Ware can it be the cause for this? Really I am unable to connect in any way. If anybody knows it please help me.
And one more thing when I am starting the VM it giving the message
"Host USB device connections disabled. The connection to the VMware USB Arbitration Service was unsuccessful. Please check the status of this service in the Microsoft Management Console."
I googled for it, according to few links,
1. I need disconnect the USB from host machine
2. I need to delete some registry entry in regedit
3. Disable the other drivers if it has
4. Check for the AMD USB drive, delete it and install the Microsoft USB driver. But in my VM all USB drivers stated as MIcrosoft, so this also didnt work for me.
I tried all of them but didnt work. If anybody has any Idea please help me, I need some help. Any help in this would be greatly appreciated.
Thanks in advance.

Check:
1. Network configuration on the virtual machine.
2. Ensure that the IP addresses are in the same range.
3. The kind of connection you've chosen... Bridged works well for me...
4. Activate the virtual network card.
5. Put the two computers in the same group.
6. Permissions.
7. Install the vmware tools.
8. Burn incense, sacrifice a goat and pray to the moon.
* With vmware tools you can drag and drop files from one place to the other one making not a must to share something.

I dont know anything about networking. Is there any way that I can do the things. Its making me very upset. I have data that I want to use in VM. Unfortunately not allowing me.
Should I create a new VM by selecting all the above options. Please give me some easy solution pls.

vmware:
1. VMWARE workstation or player: bottom right of the vm, ensure the ethernet card is on.
2. main pc: control panel => network settings => write the ip, subnet mask and gate.
3. VMWARE => go to the same place and write the same values.
4. if there is an error message then we are on the right path.
5. change the last number of the IP address in one of the computers.
6. go to the VM and create a folder (the one you want to share).
7. right click the folder and select sharing...
8. share the folder, give maximum permissions to everyone.
9. depending on your configuration it is possible that you would need to create the same user that you are using in the main pc into the VM.
10. you should be able to see the two computers and copy files or whatever.
anyway, if you want to copy files to a vm it is much easier to install vmware tools and then simply drag and drop files from one machine to the other one...
Good luck.

Hi,
Yes I am able to copy the files and folders by using drag and drop after installing the VM Tools thats really appreciable and easy instead of getting in to all these networking details.
Thanks buddy, thanks a lot.

You are welcome!
At the beginning the magic behind the VM's can be somehow strange, but you'll get use to them soon...
Glad to have been helpful!

Remote Desktop - still susceptible to Man in Middle attack?
For Windows 2008, I presume the vulnerability has been patched? (REF 2)
"In Windows Server 2008, Network Level Authentication (NLA) is designed to be secure against MITM, and it supports the ability to authenticate the server with either a SSL/TLS server certificate or Kerberos."
But it sounds like one need to be very careful with configuration ... for instance NLA don't work for scenario where connection is initiated over internet. And REF 2 doesn't discuss connection from Windows 7 or Android clients (using for example Splashtop.com). Or a service such as "www.Logmein.com"
REF 1: From 2005[^]

Hello,
First of all let me specify the
SETTINGS:
RED HAT computer:
-- 1gbps ethernet card (going from 20% to 60% and getting really small peaks of 100%).
-- 1gb RAM (using a 20% max.).
-- XEON processor (don''t know which one but it is going at a 20% as much).
- XP computer:
-- 1gbps ethernet card (going at a 2% +/-).
-- 4 gb ram (xp 32 bits, using a maximum of 1gb).
-- Core 2 duo (at 20% at much).
ISSUE:
It takes from 8 to 20 minutes to copy 1.55gb of data from the REDHAT to the XP (the XP machine is the one that started the file transmission).
I'd like to get a better file sending result in terms of time/speed...
QUESTION:
Could you give me some ideas or point me to somewhere (apart of a handkerchief to cry) in order to get some ideas/advice to improve this?
Thank you in advance!

Have you made sure it's not a local problem on one of the computers? Copy a large file (Quite a bit larger than the RAM) locally and check the speed on both computers.
Download Microsofts network monitor[^] or a similar tool and check the communication, if you have a lot of packet loss.

1.55GB in 12 minutes would be 2MB/s, that is way too low.
How are the two computers linked? are there slower devices on the same network?
How many files are involved in those 1.55GB? is it one huge file, or thousands of small ones?
What do you do to describe the copy job? Dragging in Windows Explorer? Executing your own copy code?
Is one or the other disk using automatic compression/encryption?

Thank you for your comments Luc,
- The two computers are linked using one 1gb switch. There are slower devices on the network like the router at 10mb.
- The 1,55GB are spreaded in 3138 files and 114 folders.
- I've dragged the files in Windows Explorer.
- No, not any of the disks are working in this kind of ways: no compression and no encryption.

I think there is the problem.
As an experiment: run WinZip or some other packaging utility on the one computer (locally, not across the network!), turn it all into a single, big file. Then transfer that file. Finally unpack on the other computer. And time each of these three steps. The transfer will be much quicker, possibly but not necessarily the overall process will be faster too.

You didn't mention the most important thing: what drives are you using? That's the bottleneck in these things.
Yesterday I moved a 60GB file across the network and it took 12 mins between two reasonably well-spec'd machine. I then copied across to a SAN with the fastest bits we could buy and it took 25s. Doing the same across to my portable USB drive I use for backups can take forever.

Copy
from: disk[^]
to: disk[^]
Full specs now... 
Thank you in advance for taking a look at it!

Specs seem fine. Are you RAIDing or mirroring the target drive? Do you have a lot of other network congestion going through whatever switch/router you're using? Do you have any kinks or knots in the cables? (OK, I'm kidding...)

No, no and no...
It is as if the pc's were configured to go slow... 
Cabling Cat5e...

OK, what colour are the cables? Have you tried moving the servers closer together, or placing the source server slightly higher than the target server. Electrons do have mass, after all...
Does the issue happen only between the current source and target? Do you get any speed difference to or from different boxes?

I've even shaked them a little bit to avoid that the shy electrons would not want to go through that strange/unknown cable...
It happens with all the computers... I guess this must be something with the source computer then...

My domain controller running windows server 2003 enterprise, my client running windows xp pro. I apply the GPO to enable allow incoming echo request. I found that all client are apply this setting, but when i try to ping to some client, it still request time out since i found the remote machine is up and running as normal. Any idea?

No, it is not a firewall configuration. It is within my internal LAN. It should be working since some machine are work but some are not. Any idea?

I'm not talking about your corporate firewall. Every machine runs its own Windows Firewall. Start->Run->Services.msc-> Windows Firewall. Or some other package, possibly bundled with anti-virus software.
Also, your corporate routers/switches may be filtering ICMP packets on interfaces or even down to port-level.
