TCP/IP removal

I am trying to remove TCPIP from a hp vectra PC running WinNT 4 with a 3com905 fast ethernet Card.

when i go to remove TCPIP i get the error ‘Unable to remove Name Space Provider’.
if i go to look up the properties of TCPIP i get the following error ‘external library procedure SetupChangeServiceStart reported the following error: Bad or Invalid parameters passed to open service call’

Anyone out there got a solution to this?
