Unlike Apache's built-in log rotation, IIS 6.0 requires manual configuration or scripting for proper log management. Here are the native options available:

1. IIS Manager -> Website Properties -> Website tab -> Enable logging
2. Select "W3C Extended Log File Format"
3. Under "Properties", configure:
   - New log schedule (hourly/daily/weekly/monthly)
   - Log file directory
   - File naming convention

The built-in rotation only creates new files - it doesn't automatically delete old logs. For proper log rotation including deletion, you'll need additional solutions.

Here's a robust PowerShell script that handles both rotation and deletion:

# IIS Log Rotation and Cleanup Script
$logPath = "C:\inetpub\logs\LogFiles"
$retentionDays = 30

Get-ChildItem -Path $logPath -Recurse -File | Where-Object {
    $_.LastWriteTime -lt (Get-Date).AddDays(-$retentionDays)
} | Remove-Item -Force

# Compress logs older than 7 days
Get-ChildItem -Path $logPath -Recurse -File | Where-Object {
    $_.LastWriteTime -lt (Get-Date).AddDays(-7) -and $_.Extension -ne ".zip"
} | ForEach-Object {
    Compress-Archive -Path $_.FullName -DestinationPath "$($_.DirectoryName)\$($_.BaseName).zip"
    Remove-Item -Path $_.FullName
}

For larger Windows environments, consider these commercial tools:

• SolarWinds Log & Event Manager
• ManageEngine EventLog Analyzer
• Paessler PRTG Network Monitor

To automate the PowerShell script:

1. Open Task Scheduler
2. Create Basic Task
3. Set trigger to "Daily"
4. Action: "Start a program"
5. Program: powershell.exe
6. Arguments: -ExecutionPolicy Bypass -File "C:\scripts\iis_log_rotation.ps1"
7. Run with highest privileges

Microsoft's LogParser tool can help analyze and rotate logs:

LogParser.exe -i:IISW3C -o:IISW3C 
"SELECT * INTO 'C:\logs\archive\ex%YY%%MM%%DD%.log' 
FROM 'C:\inetpub\logs\LogFiles\W3SVC1\ex*.log' 
WHERE TO_DATE(date) < SUB(SYSTEM_DATE(), 30)"

Unlike Apache's built-in log rotation, IIS 6.0 requires explicit configuration for log management. The W3C Extended Log File Format is IIS's default, storing logs in %SystemDrive%\inetpub\logs\LogFiles by default.

IIS 6.0 offers basic rotation through the IIS Manager:

1. Open IIS Manager
2. Right-click the website → Properties
3. Under Web Site tab → Enable logging
4. Click Properties → New Log Time Period

Available rotation intervals: Hourly, Daily, Weekly, Monthly. For example, to set daily rotation:

adsutil.vbs SET W3SVC/LogType 1
adsutil.vbs SET W3SVC/LogFilePeriod 1  # 0=Never, 1=Daily, 2=Weekly, 3=Monthly

For automatic deletion of old logs, create a scheduled task with this VBScript (save as PurgeIISLogs.vbs):

Const LOG_DIR = "C:\inetpub\logs\LogFiles"
Const DAYS_TO_KEEP = 30

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set folder = objFSO.GetFolder(LOG_DIR)

For Each file In folder.Files
    If DateDiff("d", file.DateCreated, Now) > DAYS_TO_KEEP Then
        If LCase(objFSO.GetExtensionName(file.Name)) = "log" Then
            file.Delete(True)
        End If
    End If
Next

Windows shops typically use:

• Microsoft Log Parser: Powerful query-based log analysis
• LogRhythm: SIEM with log rotation capabilities
• Splunk: Enterprise log management with retention policies

Though you're on Server 2003, this PowerShell snippet works on newer versions:

Get-ChildItem "C:\inetpub\logs\LogFiles\*.log" | 
Where-Object {$_.LastWriteTime -lt (Get-Date).AddDays(-30)} | 
Remove-Item -Force

• Store logs on separate physical disks from OS
• Compress old logs before deletion (use WinRAR command line)
• Consider centralizing logs with Windows Event Collector
• Document rotation schedule in change management systems
