Change MAC address of Ethernet adapter

Under Windows XP, the MAC address can be changed in the Ethernet adapter's Properties menu, in the Advanced tab, as "MAC Address", "Locally Administered Address", "Ethernet Address" or "Network Address". The exact name depends on the Ethernet driver used; not all drivers support changing the MAC address in this way.


 to check your MAC address easily on a Windows XP box, go to Run, type CMD, then type "ipconfig /all" without quotation in the command prompt. The number under physical address is the MAC address. If multiple IP are displayed, you should look under the label "Ethernet adapter x", where x is the name of your connection (which is Local Area Connection by default)

Lookup a user name and machine name using an IP address ?

 

If you need to find a username but only have an ip address,

At the command prompt enter the following command:
nbtstat –a xxx.xxx.xxx.xxx
This will list the machine name using that ip address.

 

MS-DOS-based Printouts thru USB Printer in Windows XP

How to print MS-DOS-based Printouts thru USB Printer in Windows XP

 

By default, most MS-DOS-based programs print directly to LPT1 or LPT2 port using parallel port. What do you do if your PC comes without Parallel Port?

 

if you are not using a net work please install loopback adaptor. If you don't know how to install loopback adaptor, please check my previous post Install a Loopback Adapter 
Connect USB Printer and install it on usb port. share it

 

Assume your machine as 192.168.1.10 and printer share name as PRINTER

 

Create a bat file as netprint.bat including following statements
 

-------------------------------------

NET USE LPT1 /DELETE

 

NET USE LPT1 \\192.168.1.10\PRINTER

 

-------------------------------------

Run  netprint.bat

What's the difference between .COM and .EXE formats?

- What's the difference between .COM and .EXE formats?

 

 To oversimplify: a .COM file is a direct image of how the program will
 look in main memory, and a .EXE file will undergo some further
 relocation when it is run (and so it begins with a relocation header). A
 .COM file is limited to 64K for all segments combined, but a .EXE file
 can have as many segments as your linker will handle and be as large as
 RAM can take.

 

 The actual file extension doesn't matter. DOS knows that a file being
 loaded is in .EXE format if its first two bytes are MZ or ZM; otherwise
 it is assumed to be in .COM format. For instance, DR-DOS 6.0's
 COMMAND.COM is in .EXE format as is COMMAND.COM in recent versions of
 MS-DOS.
