Hello Everyone, I hope someone can help me with an unusual problem I'm having. I have been troubleshooting this for a few days now and can't find a solution. I can't seem to backup any files or subdirectories under C:\Windows\System32 (using a 3rd party backup utility) after I integrate any post SP2 updates into my installation files using NLite. Native NTbackup works fine, but others like Veritas and Legato do not. If I reinstall SP2 after the system is built, the backup using 3rd party clients does work, but this solution is not optimal. Here are a few specifics; I'm using Windows 2003 SP2 R2 media. 3rd party clients work fine using the same installation media and then running Windows Update. No errors after the 3rd party backup clients complete, logs says backup is successful (even though c:\windows\system32\* does not back up). Turned on auditing on c:windows\system32\*, but no errors or access denied messages generated. 3rd party backup clients run under the system account (default). All systems are standalone (not in a domain), therefore no domain policies are in effect. If I reinstall SP2 after the system is built, backups work fine. (Incidentally, if I run WU after reinstalling SP2, no further updates are necessary). Standard permissions are in effect on C:\Windows\System32 "Show Hidden Files" in selected in Explorer view. I'm using NLite 1.4.9.1, but have tried earlier versions as well with the same result.
