I have three computers running Vista. Made the mistake of looking in the event log on the one running Vista Ultimate 32-bit and noticed this ominous looking error message: http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. I tried downloading this cab file and put it in the User\AppData\Local\Temp folder. I put both the .cab and the unzipped .stl versions there. I don't think that was the correct solution?! I also turned on event recording for CAPI2 stuff trying to find out who is the bad guy but don't recognize the program or application. The other two machines are running Vista Home Premium 64-bit and do not have this error in their event log. This machine had a TV Capture card using Media Center but I removed the card and installed it on one of the other systems. Any idea on what I have to do to make this error go away. The MSFT Event help information is no help on this Event. It only occurs when the system is rebooted but the CAPI2 event log has numerous Error 82's logged but it also has a bunch of other information events that look like at least a few thing are working! This is from the CAPI2 Event log: + System - Provider [ Name] Microsoft-Windows-CAPI2 [ Guid] {5bbca4a8-b209-48dc-a8c7-b23d3e5216fb} EventID 11 Version 0 Level 2 Task 11 Opcode 2 Keywords 0x8000000000000003 - TimeCreated [ SystemTime] 2009-10-09T10:30:23.400Z EventRecordID 4824 Correlation - Execution [ ProcessID] 2672 [ ThreadID] 3168 Channel Microsoft-Windows-CAPI2/Operational Computer IP35Ultimate - Security [ UserID] S-1-5-20 - UserData - CertGetCertificateChain - Certificate [ fileRef] 28B350FA24D3296AF3B7377A1F6F60FA9579E788.cer [ subjectName] Microsoft Certificate Trust List Publisher - AdditionalStore - Certificate [ fileRef] 28B350FA24D3296AF3B7377A1F6F60FA9579E788.cer [ subjectName] Microsoft Certificate Trust List Publisher - Certificate [ fileRef] E87E7804D3749674DADDF0DB4311E022B70DFBC2.cer [ subjectName] Microsoft Certificate Trust List PCA - Certificate [ fileRef] 3EA99A60058275E0ED83B892A909449F8C33B245.cer [ subjectName] Microsoft Timestamping PCA - Certificate [ fileRef] A1DC024FC8B2A76745D4661F663B8741C3D35313.cer [ subjectName] Microsoft Timestamping Service - Certificate [ fileRef] A43489159A520F0D93D032CCAF37E7FE20A8B419.cer [ subjectName] Microsoft Root Authority - ExtendedKeyUsage - Usage [ oid] 1.3.6.1.4.1.311.10.3.9 [ name] Root List Signer - Flags [ value] 100 [ CERT_CHAIN_DISABLE_AUTH_ROOT_AUTO_UPDATE] true - ChainEngineInfo [ context] user - CertificateChain [ chainRef] {A8201937-B2BA-49D8-936D-E7AB1B818AAA} - TrustStatus - ErrorStatus [ value] 1 [ CERT_TRUST_IS_NOT_TIME_VALID] true - InfoStatus [ value] 100 [ CERT_TRUST_HAS_PREFERRED_ISSUER] true - ChainElement - Certificate [ fileRef] 28B350FA24D3296AF3B7377A1F6F60FA9579E788.cer [ subjectName] Microsoft Certificate Trust List Publisher - TrustStatus - ErrorStatus [ value] 1 [ CERT_TRUST_IS_NOT_TIME_VALID] true - InfoStatus [ value] 102 [ CERT_TRUST_HAS_KEY_MATCH_ISSUER] true [ CERT_TRUST_HAS_PREFERRED_ISSUER] true - ApplicationUsage - Usage [ oid] 1.3.6.1.4.1.311.10.3.9 [ name] Root List Signer IssuanceUsage - ChainElement - Certificate [ fileRef] E87E7804D3749674DADDF0DB4311E022B70DFBC2.cer [ subjectName] Microsoft Certificate Trust List PCA - TrustStatus - ErrorStatus [ value] 0 - InfoStatus [ value] 101 [ CERT_TRUST_HAS_EXACT_MATCH_ISSUER] true [ CERT_TRUST_HAS_PREFERRED_ISSUER] true - ApplicationUsage - Usage [ oid] 1.3.6.1.4.1.311.10.3.9 [ name] Root List Signer - Usage [ oid] 1.3.6.1.4.1.311.10.3.1 [ name] Microsoft Trust List Signing IssuanceUsage - ChainElement - Certificate [ fileRef] A43489159A520F0D93D032CCAF37E7FE20A8B419.cer [ subjectName] Microsoft Root Authority - TrustStatus - ErrorStatus [ value] 0 - InfoStatus [ value] 109 [ CERT_TRUST_HAS_EXACT_MATCH_ISSUER] true [ CERT_TRUST_IS_SELF_SIGNED] true [ CERT_TRUST_HAS_PREFERRED_ISSUER] true - ApplicationUsage [ any] true - IssuanceUsage [ any] true - EventAuxInfo [ ProcessName] wmpnetwk.exe - CorrelationAuxInfo [ TaskId] {DCC5A9AE-E7BD-4661-8F1A-38248191E2FB} [ SeqNumber] 16 - Result A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file.
