Please help. I have had a Dell Windows 2008 Server for 3 years and today when logging in the system shows this error: 0xC004D401 - The security processor reported a system file mismatch error. I run my companies accounting and file sharing from this server and it's critical. The desk top only allows access to internet explorer. I found a link to a diagnostic utility and the out put is pasted below: Please help - James Diagnostic Report (1.9.0019.0): ----------------------------------------- WGA Data--> Validation Status: Invalid License Validation Code: 50 Cached Validation Code: N/A, hr = 0xc004d401 Windows Product Key: *****-*****-F9KJX-3W2R7-BB2FH Windows Product Key Hash: vblTkUu7x2n3LSpr7YBWaWFDJJc= Windows Product ID: 92573-OEM-7502905-27565 Windows Product ID Type: 2 Windows License Type: OEM SLP Windows OS version: 6.0.6001.2.00020110.1.0.000 ID: {C9E9F987-77C3-4B9A-A227-716B8B54D057}(3) Is Admin: Yes TestCab: 0x0 WGA Version: Registered, 1.9.42.0 Signed By: Microsoft Product Name: Windows Server (R) 2008 Standard Architecture: 0x00000000 Build lab: 6001.vistasp1_ldr.101014-0432 TTS Error: K:20111217133359598-M:20111213075409765- Validation Diagnostic: Resolution Status: N/A WgaER Data--> ThreatID(s): N/A, hr = 0x80070002 Version: N/A, hr = 0x80070002 WGA Notifications Data--> Cached Result: N/A, hr = 0x80070002 File Exists: No Version: N/A, hr = 0x80070002 WgaTray.exe Signed By: N/A, hr = 0x80070002 WgaLogon.dll Signed By: N/A, hr = 0x80070002 OGA Notifications Data--> Cached Result: N/A, hr = 0x80070002 Version: N/A, hr = 0x80070002 OGAExec.exe Signed By: N/A, hr = 0x80070002 OGAAddin.dll Signed By: N/A, hr = 0x80070002 OGA Data--> Office Status: 100 Genuine Microsoft Office Outlook 2007 - 100 Genuine Microsoft Office Small Business 2007 - 100 Genuine OGA Version: N/A, 0x80070002 Signed By: N/A, hr = 0x80070002 Office Diagnostics: B4D0AA8B-604-645_025D1FF3-364-80041010_025D1FF3-229-80041010_025D1FF3-230-1_025D1FF3-517-80040154_025D1FF3-237-80040154_025D1FF3-238-2_025D1FF3-244-80070002_025D1FF3-258-3 Browser Data--> Proxy settings: N/A User Agent: Mozilla/4.0 (compatible;

Thanks that worked. My Server 2008R2 Enterprise started getting the error message: "windows activation: the security processor reported a sytem file mismatch error" for no apparent reason. It would not let me log into Windows and kick be back out when it would get to "Loading user Desktop" screen. I might have been able to run the above through Safe Mode but I was able to do it through "Windows Help and Support" window which came up right after the error message. From this window i was able to launch command prompt and followed the above instructions. Mike

After several reboots the error came back... Any other ideas?

After several reboots the error came back... Any other ideas? Maybe Bruce-Liu is still monitoring this thread and will reply after all this time. I won't be holding my breath. UTC/GMT is 20:41 on Wednesday, May 30, 2012
