What version of software are you running? I have noticed issue with ssh on version 8.2(3) and below.

You can try to remove all ssh access and then add it back. Also you can try zeroizing and regenerating the crypto key.

ntoskrnl.exe is a main file that is part of windows. if you have the windows server 2003 R2 cd you can boot up with that and there will be an option to "repair" once you get so far. I would try this first as it is your best bet and can replace missing files.

expand the missing/corrupt file from i386 on your installation media to the system32 directory on the server using the bootable OS CD, select the recovery console option, not the repair OS option.

I suggest you treat your problem as two separate issues. The first is configuring a Local Area Network (LAN) with file sharing. The second is configuring the wireless communication links.

If possible, set up a "wired" LAN that performs as desired before trying to integrate the wireless links into your LAN. Hopefully you could do this with the desktop computer, one or both of the notebooks, and the wireless router. Does the wireless router have four hard wired LAN ports that function as a switch?

While they don't address the wireless component of your problem, The following Microsoft documents (downloads) are excellent resources for understanding and troubleshooting Windows XP file and printer sharing:
File and Printer Sharing with Microsoft Windows
Troubleshooting File and Printer Sharing in Microsoft Windows XP

There's quite a bit of redundant information, so you may want to start with the second document.

Basically, I'm not a fan of "wizards". When they work, you're very happy. When they don't work, you're very unhappy (and don't have a clue how to proceed). Setup the file sharing manually. The documents above essentially provide a tutorial to do that.

When you cannot see all of the server computers on the network in My Network Places or Network Neighborhood, the solution depends on whether you have successful network connectivity.

To check whether you have basic network connectivity from the browse client to the missing server computer, do the following:

1. Click Start, and then click Run.

2. In Open, type \\ComputerName (in which ComputerName is the name of the missing server computer), and then press ENTER.

If you get a window that displays the shared resources of the missing server computer, then you have basic network connectivity to the missing server computer. If you get an error message stating that the network path was not found, then there is a problem with basic network connectivity to the missing server computer.

If you have successful network connectivity to the missing server computer but you do not see it in the workgroup window, then it could be due to one of the following:

o The missing computers are configured with different workgroup name
o The browse servers do not yet have all the computers in their browse lists
o The missing computers are not on the same physical network segment

Good luck!

1. Insert the Windows XP bootable CD into the computer.
2. When prompted to press any key to boot from the CD, press any key.
3. Once in the Windows XP setup menu press the "R" key to repair Windows.
4. Log into your Windows installation by pressing the "1" key and pressing enter.
5. You will then be prompted for your administrator password, enter that password.
6. Copy the below two files to the root directory of the primary hard disk. In the below example we are copying these files from the CD-ROM drive letter, which in this case is "e." This letter may be different on your computer.
   copy e:\i386\ntldr c:\
   copy e:\i386\ntdetect.com c:\
   
   Once both of these files have been successfully copied, remove the CD from the computer and reboot.
