Configure F5 virtual server for use with Remote Desktop Gateway

A few key notes on this (not a complete guide)

Virtual Server Type: "Performance (Layer 4)"
Protocol Profile (Client): "FastL4"
  • This will benefit session responsiveness and eliminate key stroke lag

Persistence Profile: None (Do not use any client persistence)
  • This will load balance all new connections
  • This will assure that multiple users from one site are load balanced across all RD Gateway servers
  • TCP sessions are stateful, so this will not cause individual session packets to be load balanced (common misconception); only the initial TCP session set up is load-balanced
  • Use RD Session Broker and the Session Broker Routing Token to maintain TS session persistence

Configure Idle timeout
  • On the FastL4 protocol profile, configure an idle timeout of 14400 seconds (or configure to match the idle session timeout on the Terminal Server)
  • This prevents the accidental or premature reset of TCP sessions, which would interrupt the TS session and require the client to reconnect

Disable Resultant Set of Policy logging to improve logon performance

Resultant Set of Policy logging writes information to the WMI database for each user who logs on interactively. This causes the WMI database to grow, and can cause WMI database corruption.

Windows 2003
Computer Configuration > Administrative Templates > System > Group Policy
Turn off Resultant Set of Policy logging

Windows 2008
Computer Configuration > Policies > Administrative Templates > System > Group Policy
Turn off Resultant Set of Policy logging

Determine number of unique interactive logons and export a list of unique user IDs

Use to determine interactive logon information for any Windows computer (I use on servers running Remote Desktop Services / Terminal Services)

  • Download EventCombMT.EXE, part of the Account Lockout Tools
  • Create the PostEventCombMt.CMD script below

Perform the export
1. Run EventCombMt.EXE against the target servers. Filter for the following:
  • Windows 2003: Event ID 528
  • Windows 2008: Event ID 4648
  • Security log
  • Success audit

2. Drop the PostEventCombMt.CMD script in the folder with the .LOG files and run PostEventCombMt.CMD

3. Import / open the output file in Excel. Specify a semicolon delimited file.

4. Copy the Domain\Username column and paste into a new worksheet

5. Use Advanced filter to filter the list in place showing only unique records. This will hide rows with duplicate user names

6. Re-select the Domain\Username field, copy, then paste into a new worksheet. This should paste only unique user names

7. Result:
- List of unique logon IDs / user names
- CTRL+End takes you to the bottom of the list. The row number is the number of unique logons
- If you sort the original worksheet by date, you have an approximate timeframe
