Since when does NT stand for NETWORK??? Huh?? If you don't know what you are talking about, then don't talk. No point giving out wrong and incorrect information to members. Don't let me catch you giving out wrong information again.
Windows NT is what XP is based on. Windows 9x was meant for home users while Windows NT was workstation class. Windows XP is Windows NT 5.1 which is why shyammo gets Win NT as the OS. It's perfectly normal.
Now, shyammo, 128MB should be enough to run FIFA 2002 but it's possible that some other applications are eating up resources that could be used by FIFA. Try freeing up some memory before you run the game and see if it works. Does it give any error or does it just crash to the XP desktop?
