SYMPTOMS
After you run the Windows NT repair process and choose the Verify Windows NT system files option, you may receive the following error message after you restart the computer and attempt to log on:
When you follow the steps in one of the following articles to resolve this error message
196603 Repair Windows NT after installation of Service Pack 4 and later
146887 Repairing Windows NT after the application of Service Pack 3
You replace the following files in the %SystemRoot%\System32 folder:
Samsrv.dll
Samlib.dll
Winlogon.exe
Lsasrv.dll
Services.exe
Msv1_0.dll
After you replace these files, you may receive the following error message after you restart the computer:
CAUSE
This problem occurs because the Security Rollup Package (SRP) hotfix (Q299444i.exe) does not update the CRC values in the %SystemRoot%\Repair\Setup.log file for the files that are installed. The files that are installed by the SRP must remain on the computer after you run the repair process so that you can log on to the computer.
RESOLUTION
To resolve this problem, run Q307866.exe and then run Srpfixup.exe. When you run Srpfixup.exe, the current CRC values are verified for files that are necessary to start and log on to the computer. After the values are determined, the %SystemRoot%\Repair\Setup.log file is updated. This prevents the required files from being overwritten the next time that you run a repair process and select the Verify Windows NT System Files option.
Note This patch must be applied after you install SRP and before you try to run a repair process.

WORKAROUND
To work around this problem, copy the following files from the appropriate source (from the SRP hotfix or from Microsoft Windows NT Service Pack 6a [SP6A]) to the appropriate folder.
Copy the following files from either the SRP or the SP6a folder to the appropriate location:
Copy to From source --------------------------------------------------------- %SystemRoot%\System32\Advapi32.dll SRP %SystemRoot%\System32\Crypt32.dll SRP %SystemRoot%\System32\Kernel32.dl SRP %SystemRoot%\System32\Lsasrv.dll SRP %SystemRoot%\System32\Ntoskrnl.exe SRP %SystemRoot%\System32\Ole32.dll SRP %SystemRoot%\System32\Rpclts1.dll SRP %SystemRoot%\System32\Rpcrt4.dll SRP %SystemRoot%\System32\Rpcss.exe SRP %SystemRoot%\System32\Samlib.dll SRP %SystemRoot%\System32\Samsrv.dll SRP %SystemRoot%\System32\Schannel.dll SRP %SystemRoot%\System32\Services.exe SRP %SystemRoot%\System32\Winlogon.exe SRP %SystemRoot%\System32\Wldap32.dll SRP %SystemRoot%\System32\Basesrv.dll SP6a %SystemRoot%\System32\Csrsrv.dll SP6a %SystemRoot%\System32\Csrss.exe SP6a %SystemRoot%\System32\Gdi32.dll SP6a %SystemRoot%\System32\Hal.dll SP6a %SystemRoot%\System32\Msv1_0.dll SP6a %SystemRoot%\System32\Ntdll.dll SP6a %SystemRoot%\System32\Rpcltc1.dll SP6a %SystemRoot%\System32\Rpcltscm.dll SP6a %SystemRoot%\System32\Security.dll SP6a %SystemRoot%\System32\User.exe SP6a %SystemRoot%\System32\User32.dll SP6a %SystemRoot%\System32\Userenv.dll SP6a %SystemRoot%\System32\Win32k.sys SP6a %SystemRoot%\System32\Winspool.drv SP6a %SystemRoot%\System32\Winsrv.dll SP6a %SystemRoot%\System32\Drivers\\ndis.sys SP6a %SystemRoot%\System32\Drivers\\nwlnkipx.sys SP6a %SystemRoot%\System32\Drivers\\nwlnkrip.sys SP6a
If the boot partition is using the NTFS file system, you can use this workaround if you install a parallel installation of Windows NT on a separate partition or drive, or by moving the disk to another computer to access these folders. If you cannot do this, you can use the procedure that is described in the following Microsoft Knowledge Base article to make repairs:
164471 Replacing system files using a modified Emergency Repair Disk
After you use these steps and log on to the computer, you must reapply SP6A, the SRP, and this hotfix to update the %SystemRoot%\Repair\Setup.log file. After the Setup.log file is repaired, update your Emergency Repair Disk (ERD) by using the Rdisk.exe utility.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
