  1. SESSION CODE: VIR321 Effectively Debugging Complex Application Sequencings Karan Dhillon Senior Test Lead Microsoft Corporation

  2. Session Objectives And Takeaways • What will not be covered • How to Sequence an application • What will be covered • How to diagnose and repair common sequencing challenges • Learn how to use procmon for troubleshooting Sequencings • Most apps can be sequenced successfully

  3. Best Practices • Know how to install and run the application • Create a recipe • Start from a clean VM or system image • Revert to clean baseline before sequencing • Enterprise image for client • Create a Q:\ drive • Use 8.3 name for package root • Configure and test the app in the Install Phase

  4. Best Practices • Reserve free space (3x Application size) • Adding memory can also help improve sequencing times • Disable Virus Scanners, Defender, Indexing, Microsoft Update during sequencing • Create a dummy ODBC entry • Create a dummy printer entry

  5. Common Sequencing Challenges • Missing files • Unsupported subsystems • Interaction between virtual and native apps • SxS • Dynamic Suite Composition (DSC)

  6. Process Monitor Learning The Tool

  7. Process Monitor • What is it? • An advanced monitoring tool for Windows • File system • Registry • Network • Process and thread • Where do I get it? • Windows Sysinternals on Microsoft TechNet • Bing “procmon” • Learn more at Mark Russinovich’stechnet blog

  8. Operating System Virtual Environment Architecture

  9. Process MonitorApp-V Integration Works with App-V 4.5 and 4.6 procmon /ExternalCapture/NoConnect /BackingFileinstall.pml Interface with App-V virtual environment Do not monitor events on startup Save events to the PML file

  10. Process MonitorWorkflow

  11. Process Monitor – Gotcha

  12. Process Monitor – Gotcha Click Unblock

  13. Missing FilesUnsupported Subsystems Troubleshooting Netmon Sequencing

  14. Sequencing Netmon Karan DhillonTest LeadMicrosoft DEMO

  15. Missing Files • Example • VFS Exclusion results in application failure on client • Detection • Dialogs from the application • Procmon analysis • Repair • Modify VFS Exclusion list and re-sequence

  16. Sequencing ProcessExclusion Items Monitored Data SFT Parser Excluder Classifier Demo-PC→ %COMPUTERNAME% C:\Windows → %CSIDL_WINDOWS% Q:\LiveMtg\→ %SFT_MNT%\LiveMtg\ C:\Users\Demo\ → %USERPROFILE% … %CSIDL_INTERNET_CACHE% %CSIDL_LOCAL_APPDATA% C:\$Recycle.Bin\ … %COMPUTERNAME% → App %CSIDL_WINDOWS% → App %SFT_MNT%\LiveMtg\→ App %USERPROFILE% → User …

  17. Unsupported Subsystems • Example • Netmon installs NM3.sys • COM+ • DCOM • Detection • Dialogs from the application • Application knowledge • Procmon analysis • Repair • Deploy subsystem out of band on client machines • Guidance for .NET on TechNet

  18. Sequencing ProcessOpacity Reg/File Opacity Did registry key or file path already exist? No Yes Opaque (Override, Pure Virtual) Mask Local Data Translucent (Merge, Virtual) Merge with Local Data End

  19. Interaction Between Virtual and Native Apps Troubleshooting PuTTY Web Site Shortcut

  20. Troubleshooting PuTTY Karan DhillonTest LeadMicrosoft DEMO

  21. Interaction Between Virtual and Native Apps • Example • Launch of PuTTY website URL launches and exits on client • Existing IE process does not have access to Q: drive • Detection • Procmon analysis • Virtual environment policies • Repair • Modify OSD to launch separate IE process

  22. Putty Website Shortcut • Original OSD <CODEBASE HREF="FILE://C:\PUTTY\PUTTY_2.sft" GUID="36C0C5C3-D0BD-4C1E-A918-2684BBD5963B" PARAMETERS="" FILENAME="%SFT_MNT%\PTTY\website.url" SYSGUARDFILE="PTTY\osguard.cp" SIZE="3575538"/> • Modified OSD <CODEBASE HREF="FILE://C:\PUTTY\PUTTY_2.sft" GUID="36C0C5C3-D0BD-4C1E-A918-2684BBD5963B" PARAMETERS="%SFT_MNT%\PTTY\website.url" FILENAME="%PROGRAMFILES%\Internet Explorer\iexplore.exe" SYSGUARDFILE="PTTY\osguard.cp" SIZE="3575538"/>

  23. Virtual Environment Policies

  24. Exploring SxS Troubleshooting Visual Studio SxS

  25. Troubleshooting Visual Studio SxS Karan DhillonTest LeadMicrosoft DEMO

  26. Exploring SxS • Trying to run a simple program from streamed Visual Studio 2008

  27. Exploring SxS • Detection • Application error message • Event logs • sxstrace • Repair • Local install of runtimes

  28. SxSTrace • Available starting on Vista • From an elevated command prompt: • start sxstrace trace –logfile:vs.etl • Run app that uses sxs • Hit Enter in sxstrace window to stop • sxstraceparse -logfile:vs.etl-outfile:vs.txt

  29. SxSTrace Results • Need to install VC library locally INFO: Resolving reference Microsoft.VC90.DebugCRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8". … INFO: Resolving reference for ProcessorArchitecture WOW64. … ERROR: Cannot resolve reference Microsoft.VC90.DebugCRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8". ERROR: Activation Context generation failed.

  30. Dynamic Suite Composition (DSC) Word Fails to Launch

  31. Word Fails to Launch • DSC Scenario

  32. Word Fails to Launch • Launches on Sequencer • Fails to launch on App-V Client

  33. Procmon Analysis

  34. Procmon Analysis • Procmon Forensic Evidence

  35. Word Fails to Launch • Creating the virtual environment

  36. Word Fails to Launch • Workaround • Update • HKCR\CLSID\{46D1D082-1C4A-11D4-B46D-0060089D5D78}\InProcServer32\(Default) • With • %CSIDL_PROGRAM_FILES_COMMON%\Imagic Shared\WordControlDeu.dll

  37. DSC • Examples • App fails to launch • Detection • Procmon analysis • Repair • Remove short path names from secondary packages • Copy environment variables and scripts to primary package
