On a Windows NT 4.0 computer that previously had Service Pack 2 (SP2) installed, if you remove the TCP/IP protocol, and then later add TCP/IP to the system, when you boot the computer, you receive the following STOP error:
NOTE: The first argument may change but the STOP code (0x00000050) is the same in all error messages.
This error only occurs if Remote Access Service is installed and is configured to use the TCP/IP protocol as either a dial-in or a dial-out protocol.
To work around this problem, after adding the TCP/IP protocol back to the system, do one of the following:
- Reapply SP2 after adding the TCP/IP protocol back to the system, but before rebooting the computer. Click No when you are prompted to reboot, after adding TCP/IP.
- After adding the TCP/IP protocol, disable TCP/IP from your RAS configuration and allow the Windows NT computer to reboot. After the computer reboots, reapply SP2 and enable TCP/IP through RAS.
To recover from this error, use the method appropriate to your situation.
Method 1: Windows NT Is on a FAT Partition
If Windows NT is installed on a FAT partition, boot the computer to another operating system (such as MS-DOS, Microsoft Windows 95, or Microsoft Windows 3.x). Replace the Tcpip.sys file in the \Winnt\System32\Drivers folder with the one from Service Pack 2.
Method 2: Windows NT Is on an NTFS Partition
If Windows NT is installed on an NTFS partition, install a parallel copy of Windows NT 4.0 in a new directory. Replace the Tcpip.sys file in the \Winnt\System32\Drivers folder with the one from Service Pack 2. Reboot to the original Windows NT installation, and then reapply Service Pack 2. When you are done, delete the parallel installation of Windows NT 4.0.
Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem was corrected in the latest Windows NT 4.0 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
